How to download free maps to your Garmin Edge 520/705/800/810/1000 & Touring

IMG_6259-2

The Garmin Edge series of cycling computers is roughly split into two categories: Those that have a mapping function, and those that don’t.  Mapping in this case means that the units also have routable navigation – just like your car GPS does.  Whereas the cycling GPS units without mapping may be able to follow a breadcrumb trail, but can’t route you on actual streets or provide visual maps.  They’re more like an Etch-a-Sketch than a phone with useful maps.

The challenge though with the higher end mapping units (Garmin Edge 705/Edge 800/Edge 810/Edge 1000) is that as expensive as they are, they don’t actually include any maps.  Well, ok, I’ll be fair. They technically do include what’s known as a ‘basemap’.  However said basemap believes there are (for example) only three streets in New York City, and two in Paris.  Obviously with such completely useless maps, you’re not going to be able to navigate very far – or very accurately.

So instead you need to purchase more detailed maps, typically at a cost of $70-$110 per region/area.  The definition of a region varies – both in size as well as the type of map.  No matter the case, you’re spending more money on top of what you already spent.

Now there’s always been a free mapping option, but it hasn’t been until semi-recently that the process of getting these maps has been made really easy.  I outlined this within the Edge 810 review, but I wanted to call it out and make it more accessible – especially to all those owners of Edge 520/705/800/810/1000 units (also useful if you want to add maps for a region other than you’ve already bought).  Additionally, I’ve simplified those instructions some.

So here’s step-by-step instructions for how to get the free Openstreet maps onto your Garmin Edge device.

Requirements:

IMG_6312

Despite how long all these screenshotted steps may look, the whole process is actually really quick and super easy.  It’s just that I was probably overly thorough in the screenshots.

Active time: 5-8 minutes
’Baking’ Time: A number of hours
Device: Garmin Edge 520, 705, 800, 810, 1000
Storage: A $12 Micro-SD card to put the maps on (omit for Edge 520)

The step-by-step pieces only take a few minutes.  There’s a tiny bit of work to get the maps requested, which then puts you into a queue where your map request is processed and ultimately a link e-mailed to you a few hours later.  Thus the ‘baking’ time.  Then there’s a few more minutes to copy the maps to your expansion card.  Of course, there’s no reason you need to sit there and watch paint dry.  Just like you wouldn’t sit and watch dough rise.

You can get any size of Micro-SD card.  I’ve tested all three Edge units using a variety of cards from 4GB to a highest capacity 32GB cards.  I had no issues there with the latest firmware on any of them.  Most of the maps you’ll create are less than 1GB in size, so a 16GB card is more than sufficient.

Note that these steps require the Garmin Edge 520, 705, 800, 810, or 1000.  All three of these units have mapping capabilities.  This won’t work on the Garmin Edge 20, 25, 200, 500, or 510.  Those units don’t support the mapping function.  Nor will it work on any other 3rd party units.  Sorry!

Part I: Downloading the maps

This entire post is ‘made possible by’ OpenStreet maps, which are free community driven maps.  Openstreet maps have become in many areas just as good as maps from traditional providers.  And best of all, they’re free.  The below site simply does all the hard-work that you used to have to do manually a few years ago if you wanted to use OpenStreet maps.  Now, it’s literally as easy as 1.2.3.

First up, going to the site.  Which, will bring you here:

image

(Note: There are a few other free sites out there, but none offer as simple an interface, nor as widespread a geographic mapset to download)

You’ll want to then choose ‘Routable Bicycle’ as the map type.

Choose Routable Bicycle:

image

Now you’ll select which maps you want.  Because highly detailed maps like these can be somewhat large, you’ll likely need to pickup a cheap Micro-SD card.  Some smaller maps may fit directly on your Edge device, but only if you’re talking a fairly small area.  For me, I like to load up maps for anywhere nearby I might ride.

In any case, you’ll start by choosing your continent, then country.  In some areas (such as the US and Canada), you’ll also choose the state/province.

image

In my case, I went ahead and selected North America, then United States, then Washington State.  You’ll see how the map then will zoom in and show me the ‘tiles’ that represent Washington State.  Tiles are ways that the entire world can be broken down into consumable map chunks.  Tiles don’t usually map directly to states, but rather to large swaths of land – ideally designed to keep tile sizes somewhat consistent.

You can see below that it’s highlighted all tiles that ‘cover’ Washington State.

image

Now, if you plan to venture outside your selected area – or if you want to choose a smaller area, simply enable ‘Manual tile selection’, which allows you to just pick and choose exactly which areas you need.

image

For my trip to Seattle, I did just this.  I narrowed it down to just the local area that I was likely to ride in.  This would reduce my download time, as well as my transfer times later on to my device.  But, if you plan to have the maps around for a while on your device, choose a larger set so you always have coverage.

image

Once that’s done you’ll go ahead and enter in your e-mail address to build the map.  I’ll explain this in a second.

image

The service works by generating the maps for you based on your specifications.  This means it takes a bit of time, sorta like putting in an order at a restaurant.  To do this it places you into a queue, and your e-mail address is simply used to notify you when your maps are ready.

image

You’ll get an e-mail a couple seconds later with a link that you can go to and check the status of your map creation:

image

The delay may range from a few minutes to a few hours.  No worries, when it’s done it’ll send you another e-mail and you can go pickup your files then:

image

With that, click on the link to be taken to download the maps.  Once there, you’ll see you have a few options.  The only one we’re going to pay attention to is the one ending with ‘gmapsupp.zip’.  This is essentially a self-contained map file ready to drop right onto your Garmin.

image

With that, download the file someplace handy (like your desktop or downloads folder), and we’ll come back to it in a second.

I should point out that there’s a ‘Donate’ button on that site (I have no affiliation with it, nor do I even know them or ever contacted them).  Obviously, good karma dictates that if you find their (free/community hosted) service valuable, sending a couple bucks their way is probably wise – especially given how much money you’re saving.

Part II: Installing the maps

Note: For the Edge 520, see the next section for the Part II applicable to the Edge 520.

Next comes the easy part.  The file you downloaded is a standard Zip file, which means the actual map file is inside it.  Just like a package from FedEx.  So you’ll go ahead and open up the Zip file to access the map file inside (gmapsupp.img).

image

Now take your Micro-SD card and insert it into your computer via the Micro-SD card adapter that likely came with it, or stick it into the Edge unit and plug that into your computer and access it via that way.  Note, on the Edge 520, you’ll just connect your Edge 520 directly to your computer and it’ll show as a USB drive.  Follow the below instructions as normal from there.

When you do so you’ll now have a blank card ready to dump some files on…err, a single file.  First you’ll create a directory on it called GARMIN .

image

Then, simply copy/move the gmapsupp.img file right inside the GARMIN directory on your Micro-SD card.

image

And just like that, you’re done.  Well, do remember to put the Micro-SD card in the slot if you haven’t done so yet.

IMG_6318

Ok, now we’re done – for real this time.

Part II: Edge 520-specific instructions:

IMG_6013

Now, the Edge 520 is slightly different than all other Garmin units.  The reason being that the other units have a micro-SD card slot that you stick the maps on, whereas the Edge 520 doesn’t.  Instead it has internal storage (105MB total,~49MB free on a default unit).  What you’ll be doing is replacing the ‘Global Basemap’ with one local to your area of riding that’s far more detailed.  Note however that you’ve only got about 98MB of space to play with once you remove the 49MB default basemap file.  And of course you want to leave some space for your actual activity files, Strava segments, courses, and workouts (all of which are tiny, a few megabytes in total).  Simple math is 100KB (.1MB) per hour of GPS activity files.

For the most part, the steps are identical to above, so instead of re-writing them, I’ll just tell you what to do differently.  Let’s dive right in!

1) Download the map section of interest per the ‘Part 1: Downloading the Maps’ section (again for the Edge 520, remember to keep it small*: See note at end of this section!).
2) Plug-in your Garmin Edge 520 to your computer.
3) Within the \Garmin folder on the Edge 520, you’ll find the gmapbmap.img file (Disc Image File).  Make a backup copy of this on your computer for long-term safe keeping.
4) Within the \Garmin folder on the Edge 520, delete the gmapbmap.img file (after you’ve copied it elsewhere). Note: If on a Mac, you must now empty your Trash bin, otherwise you won’t reclaim the free space.  This is not required on Windows.
5) Copy the gmapsupp.img map file you downloaded into the \Garmin folder on your Edge 520.
6) On the Edge 520, rename that map file gmapsupp.img to gmapbmap.img – don’t worry if you can’t see the .IMG extension, just rename it to gmapbmap, like below.

image

image

7) There is nothing extra you need to do on the Edge 520 itself as far as configuring maps – it’ll happen automatically, so you can ignore Part 3 of the instructions.
8) Done, go outside and ride!

If you travel elsewhere, you’ll want to either copy back the backup file to the Edge 520 (overwriting your detailed maps), or just download detailed maps for the region you’re travelling to.

*When looking at the size and picking tiles on the site using manual tile selection, you can see the size on the left side.  The original map file you’ll delete will be 49MB (gmapsupp.img).  After that, you’ve still got another roughly 49MB of default free space to work with (for a total of ~98MB).  Again I’d leave at least 5-10MB for activity/segment/workout/course files though – so aim for less than 90MB for your map site.

image

Part III: Enabling and using the maps

IMG_6185

When you first turn on the Edge for the first time with the new maps, it’ll inventory the maps and then make them available to you.  Depending on how big a mapset you created, this may take a few seconds – or a few minutes.  Don’t worry, just let it complete.

Once that’s done, the map should be ready to use.  In the unlikely event your new mapset isn’t enabled, you can do so manually.  It’s pretty quick and easy.

IMG_6228

Here’s how to manually enable the map layer (again, only if for some reason it’s not enabled), on each of the units out there today (side note: fiets simply means ‘bike’ in Dutch – thus OpenBikeMap):

Edge 705: Menu > Settings > Map > Next to “Openfietsmap Lite” select the checkbox under ‘Show’

Edge 800: Menu > Wrench Icon > System > Map > Map Information/Select Map > Select “Openfietsmap Lite” and choose Enable

Edge 810: Wrench Icon > Activity Profiles > Your activity profile name > Navigation > Map > Map Information/Select Map > Select “Openfietsmap Lite” and choose Enable

Once you’ve got the maps enabled (if that didn’t happen), then you’re ready to use them.

It should be noted that these maps are fully routable, and also include plenty of POI’s (Points of Interest).

IMG_6199

To demonstrate this, you can see how I can search for various nearby eateries and find results:

IMG_6221

IMG_6202

IMG_6210

And then you’ll see how it provides routable directions on streets or even paths in this case.  For each step along the way it’ll provide ‘Turn left on Maple Street’ type directions:

IMG_6225

IMG_6205

IMG_6216

You can of course always enter in a specific address or other destination, and it’ll route to that.  And if you simply have created a course online (you can do that free on Garmin Connect and transfer it to your Edge), then it’ll provide the map information for that course as it routes.

With that, you’re ready to roll (quite literally).  Go forth and enjoy!

As always, thanks for reading!

  1. I came acrosss the site link to raumbezug.eu a few years ago. They also produce free maps based on OpenStreetMap. They have the files rebuild by country it might be easier to get the maps from here (replacing the Part I of the article). The install procedure is the same.

    Reply
    • i tried using raumbezug as I could not open the maps on OSM (I have an iMac using Max OS X 10.6.8 v1.1); i have the same problem with these maps – it says I have ‘no mountable file systems’. what does this mean??

      I am very dissapointed. Your write ups are usually very detailed. This one is very vague and poor. The part that you call easy is not easy. Your instructions that you simply rename the folder and copy are piss poor. Why don’t you actually explain how you do that. You literally showed the dimensions of every garmin side by side at every angle the fact that you would choose to leave out so many details is shocking. I have got the email and downloaded the link to osm2.pleiades.uni-wuppertal.de. I cant figure out how to open the damn thing and how to get it on my sd card. Instead of saying how it easy is and you just “copy” it why dont you actually try explaining it and show the screen shots. Then it would a useful tutuorial.

    • Hi Eric-

      I’m sorry that thousands of others haven’t had a problem with the piss-poor instructions that save folks hundreds of dollars on maps.

      To right click a folder, you simply right click it and click ‘Rename’. To copy, you right click and select copy. To open a Zip file you simply double-click it, like any other file on your computer. In this day and age, those are kinda computing basics.

      Sorry.

      Thank you for your precious instructions. I got the ZIP file openfietsmap_lite_gmapsupp.zip ok. Then I double click and I see on my screen gmapsupp.img. But when I double click on this, I am beeing offered to burn it to either disk F or G !!!. Since it makes no sense (and no action can actually happen). When I then copy gmapsupp.img to the SD card and activate it from my 800, the map screen remain blank. I have the strange feeling this is not unzipped. Please help. Thanks. Benoit

    • After you’ve copied the .IMG file itself to the /Garmin folder within the SD card (be sure it’s in teh folder, and not at the top level), validate you see the file there with that name. Then, look in the maps option on the Edge 800 and see if a map is listed there.

      Thank you for your prompt answer. I did exactly that and yet the mad that is activable from the SD card in the map sub menu of setup is blank. I have the strange feeling this is still unziped even though I did do the double click unziping procedure. But when I did it windows prompted a “disk burn” message offering to burn into a DVD drive. makes no sense to me. Have you seen this before ? Any advise ?

      The extension .img is used for a lot of different file formats. Windows assumes this is a CD or DVD disc image that can be burned onto a physical disc (like an ISO file if you’ve heard of those). You shouldn’t need to double-click the .img file inside the ZIP, just drag it out of the ZIP window and into the Garmin folder on your SD card. Also, make sure your micro SD card is formatted as FAT or FAT32 and not NTFS. Most cards 32GB or smaller should be fine straight out of the box.

      Thank you Gerard, very useful and clear comment. I did all that (also reformatd SD card) and failed again. Map page remains blank when I activate the new map on SD card. Maybe the file I received is corrupted. I shall now request a new one. In any case, thank you again for your support.

      Once again thank you Gerard. Your comments were the most useful. I have made a fresh request for a new map and followed your path (not trying to unzip) and it worked perfectly. Now there is also the possibility that something was wrong with the initial file. its size was only 15k where the second requested is 95k for the same region (unless I made a mistake of course). Anyway, ready to ride.

      As technology changes and times turn one thing that remains constant is an idiot 100 years ago is no different than an idiot today. Eric Scharlow, instead of wasting virtual real estate and attacking someone who has been a tremendous help, why not do something productive and actually try helping yourself? There is this wondering thing called Google, you should give it a try sometime.

      Anyways, this is beyond a helpful guide and literally just saved me $100. Thank you!

    • Thank you Gerard for your advice to format SD card. I spent a lot of time (several days) “to call into being” LATVIA map, downloaded from OSM, in my Edge 800 but unsuccessfully. As soon as I read out your advice I re formatted SD card at FAT 32 (card capacity 32 GB) and reloaded once more. Now it works.

      However I should acknowledge the downloaded LATVIA map is of very old version (very scanty of objects and roads). So such a map is of little use. After that I bought LATVIA map here in Riga maps shop “Jana seta”. This is excellent (very plenty of paths, roads, dwelling houses with their names and so on). I’m ready to pay but I must get guaranteed quality product. Please (it regards all Garmin Edge maps users (cyclists) from other Europa’s countries) let me know ( gunars.silins@gmail.com ): what about maps (downloaded from OSM) quality of your countries? Where do I can buy (get) quality maps of Europa countries? Thank you to all for advice. Gunars, LATVIA

      I’d recommend Velomaps. Their maps are updated weekly .
      Some maps are free, some require an annual donation allowing regular downloads of the updated versions.
      Special ‘mtb’ versions are available for mountainbikers.
      Have a look at all the information on their site link to velomap.org
      Be sure to read the Beginners Starting Guide in the Tutorials section.

      Sometimes of course, the lack of detail on any map may be due to the information not being on the OSM database. The answer to that is to become a map contributor – have a look at link to openstreetmap.org and find out more about it.

      The failure of the Mac to open these files comes about because Garmin use the same file extension .img for their map files as Apple does for disk images that can be opened by Disk Utility. If you simply click on a file with the extension .img the Mac will try to open it with Disk Utility which does not understand the Garmin files.
      Don’t worry about this, Garmin GPS units and their software Base Camp does understand these files. I got caught be this first time round as well!

      Hi Rainmaker, Thanks for the instructions/guide on the mapping thing, I am in the Netherlands and tried to use your process for the Zuid and North Holland provinces (several blocks). The Website indeed created the map and I managed to download and put it on my micro SD card on the E800 (using Finder MAC OSX) while I had Basecamp open and watching it for the change.

      All seemed to go well, but when I loaded the map, the top half seemed to be completely missing (hashed out). I retried to transfers but got the same result. I have just loaded another map to see if I get the same problem. Do you know if I need to do something to avoid this or when this might happen? Any words of wisdom would be highly appreciated. Thank you! Also for this excellent guide… Very good, would be lost without it….

      Having just received the 520 your reviews and instructions were invaluable and very much appreciated. As are the many detailed reviews you’ve done. One might say that if you were to add more detail to your reviews, that could be excessive. One thing I’ve noticed with the map feature is that while you may zoom +/- you can’t scroll away from your fixed position to try and locate a detailed route off screen. A small quibble (and not with your review). Thanks again for your help.

      Your instructions are pretty detailed and worked well for me. A small change on the http://garmin.openstreetmap.nl website, is that you don’t need to enter an email. A directory browser pops up with the files you need.

      I’m also unhappy. At no point in your instructions did you tell me I had to breathe while carrying out the actions. Hence I only got as far as step two before keeling over and fainting. Had you made the instructions less detailed I may have got to the end before collapsing from oxygen starvation. As it is now I can only ride to the corner shop and back, a route I am already familiar with. I will never ever ever use your money saving free advice ever again.

      Heads up people,

      I just went through this process last night. Grabbed the micro SD card out of my old phone (new phone does NOT have a slot) and ended up here down in the comments to figure out why it was not working in my two year old Garmin 810.

      That SD card is a 128 GB card. No joy.

      Luckily I had another 8 GB micro SD card. Worked perfectly.

      When I bought the 810 I seem to remember that the max size card it will recognize is 32 GB.

      Regardless, I downloaded most of New England, and the areas around Asheville, NC. The file for all that? 323 MB. I’m guessing I can fit pretty much everything east of the Mississippi, if not the whole of the U.S. France and Spain on 8 GB. If not I am sure the 32 would do.

      Good luck!

      I have an Edge 800, and I do have the entire USA (well, the 48 contiguous states to be accurate) on my Micro SD card. The card is 16GB, and shows 4.0GB used, 10.8GB free space. So adding Europe should be possible….

    Have you tried http://velomap.org and link to openmtbmap.org ? I have used these maps for the two latest years, and I’m really impressed by the quality of the maps – and also the web site(s).

    Very nice write-up, very useful for many.
    I have never tried the Openfietsmap Lite, only the full one, on this website you can download the pre-compiled files (link to openfietsmap.nl). There is also a hiking layer for people who would like to walk with their GPS.
    In combination with the free to download Garmin Basecamp you can make nice routes (use automobile autorouting, trust me this works best, as highways are forbidden) on your PC and transfer those to your garmin GPS. I’ve been using this for the last 3 years. The good thing is that these maps also have a DEM (digital elevation map) which enables to calculate the altitude profile of the route on forehand on the pc (or in GPS with the 62s, I do not know for the higher edge series).

    Reply
    • The full version does not contain DEM data, only contour lines. It’s possible to calculate an altitude profile on your pc but not on the GPS (for this you need a Garmin topo map with DEM data, like the recreational map Europe that is included in the T versions of the Garmin units)

    Thank you, Ray! Great explanation as usual. I have followed your steps and added a second map to my Garmin 810. I also have the Garmin North America map that I paid for. Since I am new to the 810, I am hoping you (or someone) can tell me if having two maps for the same area will be confusing to the unit and could cause issues. While they are both “active” on my device, I am wondering how I know which one is being used predominantly. If I have the North American maps from Garmin, do I even need the Open Streetmap version?

    For as much information as I can find about the ability to have more than one map on the 810, I can unable to determine how multiple maps work on the device and what I need to know to take advantage of both of them.

      You can turn off and on maps individually, I always leave the basemap switched on. This is necessary for zooming out. Then switch on the map you want to leave on for that moment. Most likely you can also rename the gmapsupp.img filename to CN-USA.img and Bikemap.img (this is for the garmin 62s), if that does not work name name one map gmapsupp.img and the other gmapsup1.img (this is the method for Nuvi devices).

      Thank you, RV. To you or anyone else, is there any point in having the Open Streetmaps and the Garmin North American maps together on the same device if the Open Streetmaps cover the same region? Do the Open Streetmaps provide better accuracy in general? I may just remove it and trust I understand the process of adding others.

      I switch back and fourth between the Garmin map and the openstreetmap. The Garmin map is less busy and more readable in dense urban areas. Off road, the openstreetmap is by far the best for trails. In rural areas both are fine.

    Question: what are the resolution (amount of details) and accuracy (difference from reality) of these maps? How are they obtained? Cartography is a tricky business, are we sure these maps are good and reliable?

      Alberto,

      I’m a longtime openstreetmap user and a small contributor. The accuracy of the maps depends on the region, but is getting better every day. And I confirm that for certain parts it is even more detailed, and updated a lot faster then commercial maps.

      As a user the only ‘problem’ I’ve had is that not all trails are on the map. Since I love walking and trail running, I’m talking mostly about really small trails lost in a forest. Most of the normal ways and roads are on the map. at least where I used it (mostly Belgium).

      But that is also easy to fix (hence the contributor part) and if you don’t want to update the maps yourself it is also possible to just upload your gps traces, or log bugs on the map so that the other contributors can update the map.

      regards

      From my experience most roads are accurate. Still need to be careful when your garmin says you are off course but only cause the road on the map is not really following the road in reality. Happened over the weekend, now to figure out if its already been fixed, if my GPS recording was correct, or if it needs fixing.

      Reply
    • Nick

      The resolution is excellent.

      In my experience (in Australia) the accuracy is slightly better than Google Maps (especially for off-road trails).

      The cycling specific maps are quite a bit better than Google Maps because they tend to update quicker. That means when the legal status of a trail changes (eg, are bikes allowed on it or not) Open Street Maps tends to be updated quicker.

      (Of course, you’ll need to download the latest version yourself manually, but that is the same in any case).

      Matt,

      I don’t if it’s legal to move the Garmin map from the 2GB micro SD card to a larger-capacity micro SD card even if you have purchased it from Garmin. Garmin has installed an anti-piracy mechanism that prevents the Edge 800 from reading any map that has been moved/copied to a different micro SD card. You will see a “cannot authenticate maps” error message.

      There are ways to break this anti-piracy mechanism but i’m not going to describe it here. You can google for it.

      Yes, it will work fine for the Oregon 450 (or the Etrex 20/30 or Dakota or Montana etc).
      The Oregon has 850MB of internal memory, so you can just copy the maps to that. You don’t need a memory card unless you want maps for a large area. Just so long as you copy the img file to a directory named ‘Garmin’ in the internal memory.

    Edge 705 units only support the singular gmapsupp.img file. Edge 8×0 units can support multiple img files so they don’t need to be named gmapsupp.img

    There are multiple OSM maps that work on the Edge units. While they all use the same base OSM data they do render the maps differently (prioritizing certain streets over others, what details are shown, making the roads look different enough from the purple line garmin drawls the course with to make it easy to follow the line, etc)

    Some are just changed around by using a different TYP file:
    link to avdweb.nl

    Some are more involved then just the TYP file:
    link to velomap.org
    They have two different map layouts: link to velomap.org

    One of these days I’ll figure out which I like more.

    In addition to the OSM maps mentioned here, you can get extremely detailed trail maps. In the case of the pacific North West (Washington, Oregon, Idaho, British Columbia), there is a great set of free maps available at http://switchbacks.com. Amazingly detailed trail maps of pretty much every trail in the region, big or small, paved or dirt. They will overlay on top of any other maps you have but are not route-able. Even better, if you come across a trail that isn’t listed, ride the trail and send them the track. They’ll add it into the next update.

    Haha, you must be sending a huge amount of traffic to them because there are 88 requests and an 8.8 hour queue right now. Last time I pulled a test map from them it was like 20 minutes for the same map (lost the file somewhere).

    Reply
    • Eli

      Short answer, garmins will be more consistent quality for all areas of the map while OSM can be much better for some and worse for others

      The free ones are mostly all based on OSM (see my comment a few up from here) As to the differences between OSM and Garmin. OSM depends on volunteers to make, fix and update the maps. So if you bike in an area with OSM contributors then the maps will be very good and will have updates as soon as a change happens but there is also the chance that OSM volunteers don’t care about a certain area.

      Garmin makes a commercial map so when that data is being compiled they mostly don’t play favorites so all areas get the same treatment so everything will be covered and updates take longer.

      Yup, I’d agree with exactly what Eli says.

      The OSM maps do have a lot of details that are not in any of the Garmin maps, eg footpaths, cycleways etc. So they can be very useful for walking and off-road cycling.

      OSM maps are available in a variety of styles. Some use the standard Garmin style, so look much the same as Garmin maps, others are designed with better colours and icons, to highlight particular things. eg the Openfietsmap highlights cycle routes. Though it does depend on what Garmin device you are using, some maps may look better than others. Its worth trying a few different OSM maps, to see what you prefer.

      I primarily use my Garmin Edge 800 in around the Seattle area so i’ll just comment on my experience with the Garmin maps versus the ones from OSM.

      The Garmin map that came with my Edge 800 bundle is version CN North America NT 2012.20. It does a pretty decent job on routing on city streets. However, for whatever reason, a huge portion of the well-known Burke Gilman Trail (a paved multi-use trail) is missing. Also, it has no information on the newer Centennial Trial. For the portion of BGT it is aware of, it would does route you to use it.

      For the OSM created using Ray’s suggested option Routable Bicycle (Openfietsmap Lite), both the Burke Gilman Trail and the Centennial Trail show up. Even though this is supposed to create a more cyclist-friendly map, no matter what i do, the Edge 800 just refuses to route me onto bike trails. Instead, it would put me on city streets even though the bike trail is close to them.

      Just like the map created using the Openfietsmap Lite option, the OSM created using the Generic Routable option included the BGT and Centennial Trail. My Edge 800, however, is able to route me onto bike trails most of the time.

    I have the 705 and spent a weekend recently trying to get open maps on my device until I saw this site. Very grateful for that and now the open maps are installed.
    I purchased the Garmin maps some 4 years ago with my unit but Garmin will not upgrade the card, only sell a new one and for Australia they are somewhere in the order of $185. Not only that, due to the ever expanding urban sprawl, a lot of new suburbs with streets are not on the maps but, they are with the Opensteet maps.
    So, in short it was worth the trouble. DC’s tutorial was inspirational and informative but, after all that I see Garmin has an 800 at an unbelievable price, unfortunately, for US and Canada only (groan).
    DC, thank you for your writings.

    I am about to purchase the Edge 810. Is there any reason to purchase the bundle for $200 more that has City Navigator on an SD card? I already have the HR strap and speed/cadence sensor. If I get the package with City Navigator, can I add the free maps to the same sd card? Do the two play well together?

    Reply
    • Changren Yong

      On my Edge 800, i can enable multiple maps at the same time but if the Garmin City Navigator map is also enabled, it will take precedence over other maps. The SD card that came with the Edge 800 is 2 GB. It only had a few hundred MB of free space available. To give you an example of the size of an OSM. An OSM including the whole state of Washington, plus portions of Oregon and British Columbia is about 160 MB. Personally, i don’t think it’s necessary to pay $200 more for the City Navigator map since the free OSM is quite good.

    • Changren Yong

      That said, with maps created using garmin.openstreetmap.nl, i do have problems with the turn-by-turn directions on some pre-defined courses (uploaded to the Garmin as a TCX file) if the starting and end points are the same or very close to one another. Instead of giving me the actual turn-by-turn directions for the entire course, my Edge 800 would produce the directions to get to the end point, not realizing that i have not actually started. The Garmin City Navigator map seems to be better in this regard. This problem does not happen to all the courses with the same starting/end points so at this moment i’m at loss as to why it works for some courses but not others. My solution for problematic courses is to move the end point further away from the starting point.

  22. Not sure if the Edge 800 already has the latest “active routing” navgation that is implemented in Basecamp.
    If that is the case, you better use Car Navigation instead of bicycle. If you have an older firmware or older models like the Etrex 700 series or the old Etrex, you can use bicycle.

    Guidance Method = On Road for Time – will prefer bicycle routes, distance will seek the shortest route

    Lock on Road = No

    Aviodance Setup Toll Roads, U-Turns…

    U-Turns = Do Not Avoid – Avoid if you want to continue and not turn back

    Toll Roads = Do Not Avoid (avoidance will route on bike routes only (“NOT available in the cycling activitiy modes!”), but this last point confuses me)

    This means you have the latest “active routing”; In this case toll road avoidance is only available in the car or motorcycle navigation. Garmin doesn’t understand I’m misusing this feature and deleted this option in their latest firmwares :( They also made carpool avoidance default in all bicycle profiles, which means unpaved roads are often avoided, see below.

    You can use motorcycle profile for instance to use a nice route with detours over bicycle routes, and car profile for more direct routes.

    Highways = Do Not Avoid (cycleroutes and cycleways are the main highways)

    Unpaved Roads = Avoid (no routing on tracks, steps and unpaved (foot) paths, except gravel bike path. Also roads paved with cobblestones are avoided.) – MTB’s should not use this option obviously 😉

    Carpool Lanes = Avoid (avoids unpaved roads, footways and steps) – same as above, recommended for a racing biker to have this selected

      The routing programming that is in the Edge 800, will not be the same as what is used in BaseCamp. You will see a closer resemblance of routing between Garmin Connect, and the Edge 800. This is due to these products being a fitness specific area. While BaseCamp is designed for our outdoor products. If you have any further questions, please contact us.

  24. Ray, thanks for the nice article. The quality of OSM data really depends if we have contributors that are interested in the area in question. In places that nobody cares about you wont see the incredible level of detail that we have in our core areas..

    To all: we have recently launched both a simplified way to report issues with the data link to blog.openstreetmap.org and a HTML5 based “beginners” editor: link to blog.openstreetmap.org

    Please if you notice an issue report it it via the “notes” function or, even better, fix the problem itself. If you don’t jump in at the deep end, adding to OSM data is easy and you can gradualy progress to more difficult things with time.

      You don’t see any maps? At the minimal, you should see the base map (this map is actually stored within the Edge 800, not the micro SD card). Is the SD card that one that came with your Garmin? If it is, you may have accidentally overwritten Garmin’s City Navigator map because that file is also named gmapsupp.img. That may explain why you can’t see the map you downloaded on the phone. Why don’t you try renaming it from gmapsupp.img to something else, like omapsupp.img. When i was using Garmin’s micro SD card (which contained City Navigator), i would rename the OSM maps to something other than gmapsupp.img so that i could choose which map to enable.

      Ok, if I’m reading you correctly, I think you did not create a “Garmin” folder on your micro SD card. You need to create this folder in the card while it’s connected to your computer. Then transfer the gmapsupp.img to that folder.

    I’m new to the Edge GPSs. In the past I have used a Nuvi for both car and bike but the newer Nuvi changes routes without announcing it even when I am not off course [No option to prevent recalculation]. Following the excellent directions I was able to download and install OSM maps. I then tried to create a track using BaseCamp (with the Garmin maps). I put it in the appropriate directory and was able to select it under courses. It displays properly on the Edge 800 but does not give me directions as I follow it. Is this what is meant by “active routing” above? Is there something wrong with my configuration or should I have created the track specifying motorcyle? I didn’t understand the comments in #51.

  33. Hello, great review, just what I was looking for before buying an Edge 810. So I did and it arrived a couple of days ago. However I have been trying to put maps on it unsuccessfully for the same past days (everything else works fine). Here is my situation in hopes that someone might be able to solve it:

    I downloaded and installed two maps from garmin.openstreetmap.nl
    I then renamed both the maps using JaVaWa GMTK
    The maps show up correctly in BootCamp and I can seitch between them using the drop down menu
    I then transfered the files to the memory card in the Edge using the “Send map to device (or something like that)” function. This took a long time, almost an hour.
    I have a 64 GB micro SD card where I have put the maps.
    When I go to: “navigation > map >map information select map” I only see the “INTL Standard Basemap, NR” enabled. There are no other maps on the list.

    I have also tried to transfer a BirdsEye demo map to the device (not to the memory card, but to the internal storage) and this doesn’t show up either.

    When I access the memory card I can see a couple of .img files in a folder named “Garmin”

    Would appreciate any help as I am getting quite frustrated since I bought this mainly for the routing features.

    • I have now successfully loaded a map, this time I put it on the internal memory and it worked. It doesn’t solve my problem however as I need to put the map on a micro SD card.
      Could it be that my 64 GB card is not supported?

      According to Garmin, the largest micro SD card supported is 32GB:

    From the Garmin site;

    What is the largest size microSD card I can use with my Edge 810, 800, 705 and 605?

    The Edge 810, 800, 705 and 605 have an expandable memory slot into which a microSD* card can be inserted. This card provides the ability to install detailed mapping to enhance the device’s internal basemap.

    It is recommended a standard speed card, no larger than 32 GB, be used in order to get the best performance from the device. Class 4 to Class 10 is considered standard speed.

  35. A couple of pointers:

    – general OSM related questions can be asked on help.openstreetmap.org (please search for an answer first)

    – coverage: I would recommend checking the map on http://www.openstreetmap.org (note: the default map is designed to give mappers fast feedback on their contributions, not to look good), if you are expecting lots of trails and tracks and don’t see any, then you might have to consider using something else. However in most of western Europe the coverage is very good.

    Besides use on Garmin devices there is a OSM plugin for SportTracks, Garmin Connect offers it as an alternative map source and there are a number of (non-sports) navigation apps for Android and iOS based devices.

    I hope this question hasn’t already been asked and answered and my apologies if it has. I can’t see OpenBikeMap as an option to enable. I followed the directions, which as usual were excellent – you can never have too many screen shots for us non-techy types. The gmapsupp, disc image file transferred to the SD and is in a folder Garmin. The SD card is installed in the Garmin slot (BTW, it is a 32 GM Card). The problem is that when I follow Ray’s steps to manually enable the map OpenBikeMap isn’t an option. The only option is the AMR Standard Basemap, NR. Do I need to disable the ANR Standard before the OpenBikeMap option becomes available? Any suggestions would be greatly appreciated. Thank you. Regards, Bruce

      How was the micro SD formatted? I have a Mac so the first time i formatted the micro SD card as exFAT, my Edge 800 was not able to read anything off it. After i reformatted it as FAT32, the problem went away.

    After downloading the map, I have created a course to follow on my ride using connect.garmin.com. While accessing the course on my Garmin 800, is there a way to still see POI’s, or do I have to exit the course?

    I am new to the area I am riding in and want to be able to see if there are any convenience stores that are either on my route ahead or how far off my route they may be.

    Thanks for any help.

      On the OSM created using Ray’s instructions, i can see icon for gas station if i zoom in on the map to the 300ft level after loading a course. You just have to make sure the Map Detail Level (on Edge 800) is at least at “Less”. If it’s set to “Least”, you won’t see any POI unless the map view level is 120ft.

      In comparison, POIs can be seen at the 300ft level using Garmin City Navigator map even when the Map Detail Level is set to “Least”.

    I got a 810 yesterday for fathers day. I like to do a mix of gravel/ road/ trail on the CX bike, especially in places without cell service. Ideally, I’d like to download a route from map my ride or google earth into the 810, and then get turn by turn directions.
    Do you have a article for “your garmin for dummies” that might help me (and others in similar siuations out)?
    I think I’ll need to begin by getting a card and downloading these openstreet maps, but I’m not even sure they willinclude the mix of trails?

    Ray are you aware of any limitations such as “the bigger the card the slower the Edge is at accessing maps off it when it gets close to full?” I am actually asking about the Edge 800 that I got during the Memorial Day sale (thanks for the link to the maps instructions here! I hope this works well on a Mac too). I’d probably look at an 8 Gb or 16 Gb card at most (finding a 4 Gb might be tough nowadays…). Is there a good rule of thumb to estimate the size of a region (e.g. Europe 4 Gb, Western America blah blah)?

    Reply
    • I’m not aware of any such issues with sizing.

      For reference, this weekend I downloaded all of France + a chunk of Spain + a chunk of UK. All in about maybe 15% of Europe from a land standpoint. It as just under 1GB.

    Thanks Ray. And all classes (4 to 10) are equally as good in the Edge? I don’t care that much about transfer time to the card that much… I figure that’s the small part of the time it takes to get maps, even though I plan to download my routes from the RideWithGPS site too. I care about how fast the Edge needs to/can read the data.

    Reply
    • Hmm, I haven’t tested to check any differences there, but I can’t imagine it would make any difference to the Edge, as it wouldn’t come anywhere near those speeds.

      Transferring data directly to the Edge 800 (i assume it’s the same for 810) takes a very long time. It’s significantly faster if you transfer the map to the micro SD card connected directly to your computer.

    Coming back to my original question, if I may, please. The SD card shows that maps were successfully downloaded to the card. The card is in my 800. The computer recognizes the card and when I click on the card the maps are in a folder named Garmin. My problem, however, is that when I try to enable the maps, the 800 dorsn’t show the map set. I am sure I missed one of Ray’s excellent steps, but I can’t figure out what it is. Any help would be appreciated. Thank you,

      Makes no difference if you have a PC or a Mac. I don’t know how to check the format of the SD card on a PC but on a Mac, you use a program called Disk Utility. In any case, even if you have to reformat it, i don’t think it’s that big of a deal. Just make sure you choose FAT32 when you reformat it. After that create a “garmin” folder (i don’t think the case letter matters) and copy the map to that folder.

      Reply
    • On a PC, you can right click the drive (assuming it’s put in an SD card reader) and then click ‘Properties’. It’ll say ‘File System:’ about 1/3rd the way down.

      Also as noted above validate that you placed the IMG file, not the .ZIP file into the Garmin folder.

    Hmmm… I call a fail in the Seattle area, and even a bigger fail than Changren Yong reported, at least with the maps in MapSource (activity: Bicycling or Tour Cycling). Look at those screenshots: link to i41.tinypic.com show two routes from Village Wines to the Fremont Troll. The closest one to the Burke Gilman trail is from the routable cycling, the other one is from the generic routing (really bad!). But as link to i44.tinypic.com show, even the less bizarre route goes to length to AVOID the bike trails.

    I sent an email to the Openfietsmap guy (girl?) after seeing Changren Yong’s post but haven’t gotten an answer. I’ll be happy to contribute some changes to OSM but am not sure which ones. For now, those maps certainly do not do a good job for bicycling around our trails… If it’s that bad in Basecamp, should I expect even worse on the device which has less CPU to compute the best route?

      Did you have avoid highway enabled? If so, that may be the reason Garmin is not routing it on bike trails as Openfietsmap considers bike trails as highway.

    • We have a fairly active US community see link to openstreetmap.us I’m sure you can find somebody there that will show you the ropes (if necessary).

      As I pointed out earlier there are a number of different producers of GARMIN maps from OSM data, typically catering for different audiences both visually and for routing. You should probably give link to openmtbmap.org a try and see if that works better for your use.

      @Changren know it must have been an “avoid highway” thing. While there is no setting for it in Basecamp, if I redo the route using “Drive” as the activity I get a route on the trails. So I am assuming this is indeed what happened there. Great! I just received my micro SD card so I can try now on the Edge 800 itself.

      @Simon, thanks for the links. I know about openmtbmap.org (and velomap.org) but like the look of Openfietsmap a lot better than theirs, and wanted a way to get started quickly to try without getting into their premium content buy (I have a Mac).

      Is openstreetmap.us a good place to ask about things comparing both (for example it seems that Velomap may have global DEM while Openfietsmap does not in the lite version but I am not sure)?

      @Changren do you still see your issue with “routable bicycle” with the latest maps from Openfietsmap? On the desktop at least now that I picked Drive to have highways the trails are hit… I may not be able to get close to the Burke Gilman trail for a while to test with the Edge.

    Ray, How do you add more than one state or country to the SD chip in the Edge? I downloaded Colorado and once it appeared as a 97.8MB file called “gmapsupp.img” I drug it into my Garmin folder and the maps were enabled on the Edge. But when I tried to add a second set of maps, of France where we’re going this fall, the same file name appeared, this time a 742MB file, which would not load when i drug it to the folder. I tried renaming the file “gmapsupp1.img” and then it would load in the folder but no France maps appear when I go to enable the maps, nor can I find any French locations such as cities etc. when i search. Thx.

    • You’ll need to use the procedures I outlined within the Edge 810 review (around Basecamp to combine them, applicable to older Edges as well). That said, I thought someone said that you can now put multiple .IMG files named separately onto the Edge 810 with a more recent firmware. I just need to try it out.

      It sounds like you downloaded the wrong file. You need to download the file named “openfietsmap_lite_gmapsupp.zip”. Then when you unzip that, it will contain a file named “gmapsupp.img”. So just copy that onto a memory card in the Edge, in a folder named “Garmn”.

      1- On Mac platform when you download the Openfeitsmap.zip file it downloads as “disk image” with extension .img (gmapsupp.img) in your downloads or documents folder (based on ur settings)
      2- IMPORTANT: Insert MicroSD card, it will show on you Mac desktop, click it, create a “folder” named “Garmin”
      3- Now drag the gmapsupp.img file into the “Garmin” folder in the MicroSD card
      4- Eject both Garmin and MicroSD
      5- Your maps on!!!

      I was simply dragging it on the MICROSD card and it was not showing, you got to create a FOLDER!

  55. I’ve hit a bit of a snag while trying to add a second map and am hoping you guys might know what I’m doing wrong. I’m currently getting the error message, “Cannot Authenticate Maps”.

    I’m interested in having three maps on my 800 – the AMR Standard base map (on the internal drive), the OEM CN North American NT (gmapsupp.img map 1.4mb), and an added Open file for North America, which I’ve named openmap.img (3.9mb).

    I’m using the 16mb card recommended in the article above and had the maps independently working when replaced the default map with the larger Open Map – then named gmapsupp.img. Since trying to run multiple maps, I’m hitting the snag. It appears that when I try to load everything to the SD card, the Garmin will be able to find only the AMR and Open maps – not the OEM “CN America NT”.

    Here’s what I currently have on my 16mb SD card when I access it via my computers SD slot (I get a lot more when I plug my Garmin unit it via USB).

    /Removable Disk
    GARMIN (folder contents listed below)
    pmp_usb config file
    winamp_metadata dat file
    winamp_metadata.idx

    /Removable Disk/GARMIN
    /Activities (empty folder)
    /Courses (empty folder)
    /NewFiles (empty folder)
    /Workouts (empty folder)
    gmapsupp.img (1.4mb default map)
    openmap.img (3.9mb Open map I created)
    grmn0.gma
    Gmapsupp.unl

    Any ideas what I’m doing wrong? Does it matter if I load the maps via SD port or via the 800 plugged in?

    Thanks,
    Matt

      Matt S:

      I think you got your unit wrong. The Garmin City Navigator map is about 1.4 GB (not MB). I don’t know the legality of moving the Garmin City Navigator map from the micro SD card that it originally came with to another micro SD card with larger capacity. But the reason why you are seeing the “Cannot authenticate map” message is because the Garmin map is hard-coded to that specific micro SD card. When you copy that map file to another micro SD card, your Edge 800 realize the map is not on the correct valid micro SD card. I believe Garmin did this to prevent piracy of its maps but it is a pain in the ass for people who legitimately own it and wants to move it to a micro SD card with larger capacity.

      There are ways to get round this but i am not going to post it here. You can google for it.

    I’ve ordered an 810 with City Nav Europe and the 1:50 UK Discoverer bundle. (not yet arrived).

    Will I be able to load OSM maps also?
    Will these have to be put on a separate card (not ideal to have to change cards if you want a different map)?
    Can the OSM maps be loaded onto the 810’s card? If so, is there any chance I could overwrite the City Nav EU or 1:50 Discoverer maps by accident??
    If not enough space on the 810’s card can I transfer the City Nav EU and 1:50 Discoverer maps onto a larger card and add on the OSM maps to the same card?

    • You can mix maps, but you’ll need to use the steps outlined within the Edge 810 In-Depth review to dive into how to merge the two.

    Has Garmin Connect essentially replaced Basecamp if you use an 810?
    Is “Courses” in Connect the same/better/worse than Basecamp?

    Reply
    • Yes and no. It’s complex.

      Basecamp is definitely the core product for transferring maps to the unit (as opposed to Garmin Connect, which today can’t transfer maps). It’s also the product if you’re going to do any transferring of complex navigational waypoints – another area that Garmin Connect can’t do.

      For me, if it’s just a route, I prefer Garmin Connect – and especially with the Edge 810 because you’d be able to access those and transfer them from the web. Also, snap-to-road functionality is within the site and definitely better there.

      Did you download the file openfietsmap_lite_gmapsupp.zip? It does not matter if you are following Ray’s instructions or Haroon’s, this is the file you should be downloading. Depending on the browser and the setting of in your browser, it may unzip it automatically for you. I’ve configured Safari not to extract/open files automatically after being downloaded so any zipped file will remain compressed in the Download folder. If you situation is similar to mine, then you have to double-click on openfietsmap_lite_gmapsupp.zip to uncompress it. The resulting file should be called gmapsupp.img.

      Again, DO NOT download the file from Openfietsmap that says for MAC OSX. This file requires a couple of Garmin apps on the Mac in order to transfer the map to your Edge 810. This process is a lot more complicated than the instructions described in this post.

    Love the site, thanks! Two questions (for now). Just got a Garmin 800. If I want to have maps for two areas, say my home base and a vacation map would you just swap out the map file on the Garmin or can one of the maps be renamed as the maps have the same name. Or can you create a map with two separate areas. We vacation in the same spot. Secondly how often do update the map of your home base?

    Reply
    • Yes, you could swap out maps (simply have them handy on your computer). Or, you could go ahead and use the site above to build a big custom map set with your vacation spot and your home spot. Then you’d just have one map set.

    A big thanks to Ray for these great instructions on the map download! I`ve got the Edge 810 now for about a week, and since I got a little bit of time on my hands I started to play around with a lot of different maps to see the differences.
    First of course, I followed Rays instructions and downloaded the routable bicycle map from the suggested link. Everything works fine, but the thing that annoyed me (as a hiker AND biker) is, that there are no elevation lines included on these maps. (or did I miss anything?) I don`t know why, but I just love these lines…they let me easily spot a nasty hill in the area to circumvent :-) So, next I downloaded the maps from openfiestmap.nl, and these maps are great – they include elevation lines (I think this is how you call them, right?) and show great detail. However, the routing is not that great when compared with the original Garmin maps (even though mine are from 2009 and have never been updated…for obvious reasons…). In this case, I particularly compared the topo Austria (Garmin) with the Topos from the above mentioned pages.
    This is really my only complaint…the routing function (on the GPS device itself) is somehow weird, which I guess has to do with the attribution of certain trails. I don`t know if anyone has made the same observation, but when I use different modes (e.g. Hiking vs. Mountainbiking vs. roadcycling) the device selects sometimes forest trails with roadcycling or roads with the Hiking mode. It works so-lala, but not as good as with the original Garmin maps.
    I also downloaded the maps (both, velomap as well as mtbmaps) from openmtbmap.org after donating some money. Here my experience was even worse – the routing function does not differentiate between the various modi at all – even though all these maps are based on the OSM maps. So here goes my confusion.

    I now wonder, any suggestions out there in terms of really good, routable maps (for all uses, roadcycling, mountainbiking and hiking) including elevation lines? The openfiestmaps are already pretty good, but not amazing (instead of hiking I have to for instance use the “by foot” mode in order to walk on small trails). Also, very often I am getting routed along main roads instead of cycling tracks which are running parallel.

    Any help or suggestion is appreciated.

    Help! I am new to loading maps on my Garmin 810. I downloaded the map for France onto my Mac and transferred the map gmapsupp.img into new files on my 16 gb micro SD card. The file shows up as being on the card when it is plugged in to my Mac but it does not appear on the Garmin 810 when I unplug from the computer and boot the Garmin. I only see AMR Standard Basemap, NR. What am I doing wrong? Thanks.

    You are putting it in the wrong folder on the micro SD card. It should be the “Garmin” folder, not the “new files” folder.

  77. According to Highly Tuned Athletes owner Mr Rob Grinter all the problems I had with my Garmin Oregon 600 recently occurred because I was using OpenStreetMapping. The maps caused the following problems which I raised with Garmin International (ignored) and Highly Tuned Athletes. Apparently my use of <a href="link to openstreetmap.org was irresponsible and the cause of these issues as it seems it works fine for them at their store … (with those same maps installed BTW). I experienced all of the below whilst riding in the South-west of WA. It seems that the disclaimer at link to garmin.openstreetmap.nl where I download the maps from explains these issues.

    I have found Mr Grinter’s comments rather interesting given that these same maps worked fine initially, work fine in my Garmin Edge 810 and seemed to work fine at Highly Tuned Athletes store.

    Anyway just putting out there what I experienced and if you have a Garmin product and use Openstreetmaps and experience any issues you might want to remove the maps before returning the unit for investigation.

    The following is taken from my letter to Highly Tuned Atheletes.

    1. My Garmin Oregon 600 not synchronise with either of my Garmin GSC-10 sensors despite both advertising material and the manual indicating otherwise. Those same GSC-10 sensors synchronise with Garmin Edge 810 and previously with my Garmin Edge 800 so I know the issue is not with the sensor. Interesting the Oregon 600 will synchronise with my Adidas HRM strap. I consider this critical failure as it was one the features I lead to my purchase of the unit. Any replacement or repair must have this functionality working correctly please or there is little point in replacing or repairing the unit.
    2. The Oregon 600 has been inconsistent with its auto-pause function. Sometimes it will auto-pause sometimes it will not. The amount of tree coverage appears to have no influence on this. I have found that on more than one day, a day of riding could be recorded with approximately 60% being added to the day’s distance when compared to the map. I didn’t deviate from my planned route at all and hence this sort of error level is extremely concerning, more so if one is navigating and using distances as a critical navigation tool. I found the only solution to this was to physically turn off the unit whenever I stopped.
    3. In contrast to the issues raised in dot point 2, I found I could be riding along when the Oregon 600 would simply go into auto-pause mode. This was a known fault in early firmware updates of the Garmin Edge 800 and which was fixed so it is staggering to see it happening again now with a much more modern unit in the Garmin range
    4. I found the Oregon 600 showings speeds up to 30 to 40 km/h when I am doing 10 km/h or less and again in situations where often there was little to no tree coverage. On one day it recorded a maximum speed of 90 km/h! I was riding a loaded mountain bike on dirt trails where my average speed would have been around 10 km/h over the day.
    5. The Garmin Oregon 600 route tracking gets confused following a turn in the road or trail and often then heads off showing me going well off-track and adding considerable distances to the day’s ride distance.
    6. On more than one occasion it would simply just recorded me heading off into the wilds for no apparent reason;
    7. My Oregon 600 regularly looses satellites even in clear tree coverage (e.g., riding in farming country). When this occurs I have to use the auto locate satellites feature to re-locate the satellites. When I do this the Oregon 600 finds the satellites within seconds. On some days this was happening up to 15 times over a six to eight hour ride. In my view this is a very serious concern as surly a company such as Garmin Limited with a history of GPS development should have such a fundamental functionality working correctly.
    8. If I switch to external power source (e.g., USB battery supply) it causes the Oregon 600’s screen to change to a different display and at times simply changes the chosen the profile! It simply seems to have a mind of its own.
    9. I found that a set of Duracell Ultra alkaline batteries I tried (fresh purchase) lasted no more eight hours which is well short of the claimed battery life. I was getting similar battery life times from a rechargeable batteries as well;
    10. My Oregon 600 will at least once a day randomly turn off;
    11. My Oregon 600 will lock up requiring the removal of the batteries to force it to restart again seemly on a random basis;
    12. Tones continue to sound even though they have been turned off in the settings
    13. Updating to firmware 2.8 resulted in the lost of the geocaching profile as per our email discussions.

    Regards
    Andrew

  78. This is excellent!

    I have a 800 and travel a lot. I have a mac and just have a folder on my desktop with various maps from around the world. Found that my 800 doesnt like 2 maps at a time so I just delete any off the card Im not using and have them backed up on my desktop folder.

    Example: Yesterday was in Thailand so I had the thai maps and nothing else. Today in NYC and have the NYC maps and nothing else. All my maps are on my mac so can delete and add anything to my micro SD card ‘garmin’ folder anytime.

    Im pretty computer illiterate but found the support in this thread very helpful. Especially Mr Yong.

    Thanks for this great help. On my new Edge 800, I find no problem downloading multiple map files to the SD card. To do this, you have to give each file a different name, but the 800 seems only to use one file named GMAPSUPP to do routing. So I give the files I am not using temporary other names, such as GMAPSITUPP for Italy and rename the file I want to us as GMAPSUPP. This lets me store my files on the SD card in the Garmin, and just takes a minute on a computer to change the map file names when I change locations. This seems easier than creating the “one big map” each time I want to add something, but keeps the files handy and ready to go. Is there an easier way to do this?

    I had thought it would help the Edge 800 to run faster if I had separate smaller files for each area I wanted to cycle in. I created two small files, renamed them and uploaded them to the SD card. Garmin calls them both Openfietsmap and seems to load them both.
    How can I identify them as separate files so I can select them individually? Does it make any difference to the speed of operation?

    Reply
    • davep

      The name the Garmin displays is from inside the file. It might be possible to change it but not very easily. Anyway, I doubt it matters for speed: the Garmin isn’t doing anything with the name beyond displaying it.

      By the way, from my investigation, the “openfiets/bicycling” versions do not produce very good routing if you are in the US. (That is, when you use the Garmin like a car nav unit to compute a route to a destination).

      If you use the Garmin to compute routes, you might consider using the normal (non openfiets/bicycling) versions of the OSM and use “avoid highway”.

    Hello there,

    I am in a bit of a blind panic. I am not the most technical person in the world but I bought an Edge 800 expecting it to have routable maps on it. After forking out a fortune i realised it has none and I am currently t-2 days away from a bike ride from London to Berlin, where we were expecting to load the routes on to the Garmin. A few questions, do I need to have the SD card, can i just download on to my MacBook Pro and then transfer over? I have asked for whole of the UK, parts of Holland and Germany. When do you reckon i can get it all done by.

    I’ve struggled with doing turn by turn ride with my 705 even after buying the east and west north American maps from RWGPS. I’ll upload the ride, get going then it’s telling me to make a u-turn or make a wrong turn then there a map lines all over the screen. Garmin support sux and RWGPS has been tough as well.

    Any advice, forums I can go to? Could it be the maps, the 705? feel as if I’m missing something simple. Any help would greatly appreciated.

    Reply
    • Yeah, I don’t have really any experience with RWGPS. But, there tends to be a fair bit of folks willing to help out in the Garmin forums – forums.garmin.com, which may be a good option to try and troubleshoot.

      Typically speaking, if you’re getting wonky directions, then the base mapset may be a problem. The good news is that trying the free solution above doesn’t cost anything (maybe $10 if you don’t have a spare MicroSD card around), but may be a quick way to eliminate one of the two items as the core issue.

    If you would like free topo maps for your 800/810 you should check out link to gpsfiledepot.com . You will need to download install each state individually into Garmin basecamp and then generate a file to upload to your gps. There is a bug with installing in windows7-64 bit which requires downloading and installing a small trail map such as link to gpsfiledepot.com first. Enjoy and happy cycling!

    Hi there,

    I successfully downloaded the UK earlier in the year, but has since returned by broken 705 and received a reconditioned 705 from Garmin. I bought a new SD card but since downloading the maps, I can no longer view the maps when I open the Garmin 705. I’ve copied the gmapsupp file onto the SD card and even the actual device, but I can only see the basemap – anyone out there know why?

    I’m real close to throwing my 705 in the trash. I bought a eastern North America map from ‘Ride with GPS’ and it sucks. I’ll map a ride then take off and with in just a few minutes it starts telling me to make a u turn or deviates way off course. Garmin has ZERO customer service and these instructions seem to go over my head.

    Really, REALLY frustrating. This thing was supposed to take stress out of long rides not make them a hassle.

      See if there is a setting about navigate to start. I had similar issue with my 800. I was on the route but it wanted me to go to the start of the route and I had jumped on in the middle. Also if it asks you to allow re-calibration say yes. I used a route for the first time last week and it worked great. Try setting up something around your house or neighborhood till you get it figured out. Good Luck.

      I’ll give the instructions provided by DC Rainmaker one more go than I’m back to the old Map My Ride app on my ‘smartphone’ which as of last time I checked they didn’t have turn by turn available which is what led me to the Garmin.

      It tracks me perfectly but that’s not what I bought the Edge for or the maps from RWG. Part of me wonders if I’m not going to the wrong place on the Edge to retrieve and do the routes I create. I’ve NEVER seen worse owners manuals and customer service than Garmin’s but when you’re the biggest and baddest on the block thumbing your nose is pretty easy…..

      When I attempted to load the Open Streets map this is the error message I got “The Finder can’t complete the operation because some data in “63440393.RGN” can’t be read or written.
      (Error code -36)”

      I’m about over this whole thing. I spent quite a few dollars on all this and so far it’s a waste. If all I wanted to do was track mileage I’d have just kept using my Forerunner 305.

    You mentioned in your – excellent – article that it is possible to place maps directly onto the Garmin (not on a MicroSD card), but didn’t explain any details. Since I have just received my Garmin Edge 810, I thought I would comment that this is trivially simple.

    Connect your Garmin via USB.
    Copy map file into the Garmin directory.
    On Linux this will be /MOUNT_POINT/Garmin
    On Windows this will be REMOVABLE_DRIVE:\Garmin

    You can try this simply with a single map tile from OpenStreetMaps as discussed in your article

    The Edge 810 that I received presents one storage device which reports 110260224 bytes in size. Just under half of that is already used by default data files on the device. That means you have a mere 5 6Megabytes remaining. Assuming you want the Garmin to track, and store data about your activities, this will be further reduced, I would imagine it is reasonable to expect that you could load a map of 35-40 Megabytes and still have enough space for the other stuff.

    So, how big geographically is a map 35-40 Megabytes ? That’s not so easy to say because it depends upon the information density within the map. For example, Half of the North Atlantic Ocean and southern tip of Greenland (link to osm.pleiades.uni-wuppertal.de) is only 5 Mbytes, whereas the City of Munich Germany (link to osm.pleiades.uni-wuppertal.de) from is about 7 Mbytes. The entire state of New York would require approx. 75 Mbytes. Still, having four or five tiles composed into one map image is perfectly reasonable, especially if you are using the device for sporting activities, since you are unlikely to require more than 2 or 3 tiles per day, unless your sport is something to do with a motorized vehicle (IOW – not really a sport)

    Forgot to mention. You can also free up additional disk space on the Garmin by deleting unnecessary foreign language files.

    There are 2 locations:

    GARMIN_DEVICE/Documents/Files/pdf
    Contains the same document in multiple languages.

    GARMIN_DEVICE/Garmin/Text
    No idea what these are, but clearly they are the same information in multiple languages as well.

    I deleted everything not English, and now have 94 Mbytes free space. That’s more than enough for the entire map of New York State previously mentioned.

    When I put the card into the 810 and follow the instructions all the unit shows is AMR standard base map NR.

    Between downloading the OSM, then deleting them from the card and the open stream email request route I’m about 24 hours into this process and about to throw it out the window. Please help!

    I followed the instructions and loaded the map to my 3 year old Edge 800. The map loaded on the MicroSD card and I enabled it in the Edge 800 but I cannot see it in the display. I have the Garmin/Navtec North American maps on an MicroSD card but wanted something more up to date and detailed.

    This is what I did. First I renamed the existing gmapsupp.img file on the card and realised the card was too small for the OSM file I had created. I tried renaming the existing file back to gmapupp.img and enabled it. No maps appeared on the GPS. No problem since I now know how to load the new file, I purchased a new MicroSD card and transferred the OSM maps as indicated in the newly created Garmin folder and as indicated above, the maps do not load on the GPS. I checked back in the menu, it identifies the file, it shows enabled but the maps fail to appear. I’m sick of this GPS, it give me all kinds of grief (losing satellite reception, corrupted files, HR, speed and cadence spikes). I recently perform a reset but satellite reception goes away at times in the middle of fields. Now I have no maps, this is not an improvement!

    At this point I’m not sure if I should buy a new Edge 1000; will they be more reliable? Has anyone have any idea how to fix this?

    Reply
    • It’s hard to say where the error is occurring with respect to your current Edge 800. I’d agree that the new card route sounds like that should have worked, so I suspect it may just be some sort of issue within the steps.

      That said, the other issues aren’t normal (GPS/corruption/etc…), and definitely not anything I see on my Edge 800’s (which I use weekly for testing of power meters).

      As for the Edge 1000 – it’s far too soon to know where it stands, since it won’t be available till June.

      It was an interesting problem, I went riding with the GPS and while I could not see the map, and I was still getting info like riding on route 5 or approaching main street.

      I downloaded a new OSM map from the server with a smaller area (Quebec and Ontario) and after putting it on the card, I disabled and re-enabled the OSM on the GPS and the map finally appeared! I did not do anything different but it now works. I will be able to use it until I pull the trigger and buy a new one, probably an Edge 1000. The OSM maps appear to be lot more detailed than the Navtec maps I used to have.

    Hi Ray,

    Thanks for this post! I’m considering getting the 810 as the 1000 has caused them to drop to a suitable price! However, I’m looking to get all of Europe on to the 810 as I’m doing a bit of touring over summer, would that be possible with an 8gb sd card do you reckon, or would it need to be bigger?

    Also can you charge the 810 whilst on the go? I’ve heard the 810 usually has about 14 hours battery life but some days I may be out longer so it’d be awesome if it was chargeable on the go!

    Thanks

    • You can indeed charge the Edge 810 on the go, no problem there.

      8GB might be enough, assuming you know where you’re going and can load smaller map sets (versus trying to load all of Europe). Otherwise, it may be worth it to get a slightly bigger card, since they literally only cost a few dollars extra.

    After three days of using all my free time to upload the maps and all the associated software to use the Garmin site and map streamers I was still no nearer getting the 810 to see the maps which my MacBook showed as loaded on my sd card, I decided that I should just get out and ride.

      Hey Julian, check out what I did. Believe me I know as I went through something similar.

      Do you see the map on the list in the Garmin? If yes did you enable it? If is shows enabled, ensure that you zoom-in as you may be too far to see the map. If you still can’t see the map try disabling then re-enabling and zooming. If this does not work, I suggest you try loading a smaller map area. I suspect the larger file may sometimes have difficulty loading properly for some reason this is why I made my map smaller. I hope this works for you.

    I just made an OpenStreetMap of the contiguous 48 United States, using the instructions here. The only way I could find to do It was to select a state, then add tiles to include the other 47 states. Is there another way?

    Is there a place I can make a suggestion to allow mapping the entire country? This seems like a simple enough idea….

    By the way, the map I created is about 3.25GB in size, so it fits comfortably on just about any microSD card you can buy these days. I bought two 8GB cards so that I could give the maps to friends who have Edge 705 or 800 units, but did not buy maps.

    • I’m not seeing an option either for the whole US. I’d agree though, it’d certainly make sense and likely be a reduction on their server processing workload (albeit potentially not bandwidth).

That confused me at first as I thought I had placed the map files in the wrong folder but I realized quickly that the card and the unit are shown separately.

    Hi all,

    Question on new Edge 1000.

    About the new Garmin Edge 1000. Any idea if the new coumputer allow to upload free maps just like the previous Edge 705/801/800 etc?

    Firstly, thanks so much for these instructions, incredibly useful.

    I’ve been using the UK maps for nearly a year now with no problems, and I now want to use over in France this July.
    I’ve downloaded the map for France, but I’m concerned that as the file names for all maps are the same (gmapsupp) that it will replace my UK maps.

    Any advice would be great

    Thanks

    Hi Ray,

    Is there anyway to download all of Europe at once, or do you have to download it country by country – as you can’t highlight the whole of Europe (I presume you can install multiple countries separately)?

    Thank you for your generosity, time, and patience! Your directions and information is one of the clearest and most easily understood device updates I’ve seen, definitely beats some of the phone customer service out there!

    Although I just bought an Edge 1000 to replace a perfectly functioning Edge 705 I find the information you’ve provided to be invaluable on both platforms. My only complaint is with myself for not having found this resource sooner!

    Thank you greatly and happy riding!

    I have tried to go through this process twice now but when I try and unzip the file I always get the following error message:

    Cannot open file: it does not appear to be a valid archive
    If you downloaded the file, try downloading the file again

    Any suggestions. I am leaving for the US on Friday (from the UK) to do a 2500 mile trip and really need these maps!!

    Many thanks in advance

    • Definitely sounds like a download issue where the file may have had a problem on the download and thus got corrupted (not uncommon). I’d try downloading again from the link you have (no need to re-start the entire process, just re-download the files).

    I can confirm it I had that problem. I requested the map again and it all went well. One way of confirming it, is by comparing the relative size of the 2 maps.

    great comments and thank you for the all the informaiton. I am going to northern italy next week and downloaded a map accordingly. I own a mac and it looks like the file gets unzipped during the download, rather than me opening it. Than I transferred the file to the garmin drive on the micro chip, that looks like it worked. I inserted the chip into the garmin 810 and activated the unit, further I enabled the map. I was able to see italy and larger cities, but not streets or POI, so I am not sure if it works. I than re-inserted the north american map and went riding, but noticed that grades were not being captured correctly and streets were not being displayed.

    Any suggestions.

    • It sounds like the map isn’t correctly being pulled up (just the default basemap). Be sure that you actually did unzip the file and place the inside file within the Garmin folder, as it sounds like that may be your issue.

    Looks like I had either a faulty card or the Garmin doesn’t like 32GB. Got a new 8GB card and every map I wanted downloaded as described above, talky toaster for UK and the routable bicycle route maps for Spain, France, Italy and Switzerland. All seem to work fine and in great detail, down to 20 feet.

    Great work! I bought an Edge 1000 with EU maps for a trip to France and added a Singapore map (I live in Singapore) in microSD – all worked fine. I have now added a Sydney, Australia map on the same SD card. To keep the maps separate I have added “sin” and syd” to the end of the gmapsupp filenames. I can see both maps are enabled (with the same name) but neither seems to work.Will find a recent found location but no maps shows. Is it possible to have more than 1 map in the Garmin directory on the microSD card?

    Hi everyone and thank you very much DR Rainmaker for all your awesome articles, including this one :)

    I followed every step on your tutorial, I am sure the custom map is inside my microSD card and the microSD card is well installed in the Edge 800, but when I turn it on it doesn’t recognize any maps from the microSD card, nothing shows up in the map selection area except for the base map. The microSD card is 64GB, could this be the issue? Should I get a smaller card?

    Thanks,

      Hi, I don’t know the specs of your Garmin Edge unit but I suspect that a 64GB card may not work. Here is answer for a similar problem with an Etrex 20 unit:- “The problem is solved. Finally. The problem was the SD card (16GB). I replaced it with a different brand and smaller size (8GB) and everything worked fine.”
      That answer came from this thread link to help.openstreetmap.org on the OpenStreetMap help site forum.
      Hope this helps.

      Thank you very much, NZGraham!!! I’ll try to do that, get a smaller card and see if it works. I tried my Garmin Edge 800 today for the first time and the basemap is really worth close to nothing, hehe :)

      Thanks!

      I had / have the same problem…
      If you repartition the SD card to 16GB formatted as FAT32 (I’m not going to explain how to do that beyond saying that there are free partition manager apps out there that will handle USB devices – if you don’t understand then please just go and buy a smaller card – you’ll save yourself pain) then it works for an Edge 800 at least.

  134. I recently purchased a Refurbished 705 (without maps) because I couldn’t justify the cost of getting a brand new Garmin Edge (and then buying maps).

    I “more or less” followed your instructions (great for getting me started down the right path, but then I explored other options at different decision points :-) ).

    I have BaseCamp and when I saw there was a “Windows BaseCamp Map Installer” [openfietsmap_lite_windows.exe] I went that route. Once installed into BaseCamp, one can use BaseCamp to install the maps onto your device.

    I ran into some issues that I want to note here for those going this route:

    If you select a predesignated region (state of Massachusetts), the map will install on BaseCamp with a unique name, That makes it easy to download and install different regional maps into BaseCamp.

    However, if you create and download a custom set, the custom set will always have the same generic name. This means that you cannot install multiple “custom sets” into BaseCamp because one generically names install will overwrite any other generically names install.

    So if you are going to create a custom set of maps (spanning different regions), it is best to do it all as one download.

    Thanks DCRainmaker for saving me at least $100 in map purchases!

    Hi, Thanks for your instructions for downloading Open street maps onto my new garmin 800. I eventually downloaded the UK maps. I am now trying to add a second country to the sd card, but it does not show up at “show map information”. Do I just need to try wiping the second map off the sd card and trying again (for the 4th time) Or give up and put the second map on a new sd card?

    Thanks for the advice.

  139. Hi Ray,

    thank you for writing this post. I have been coming back to your article whenever I had a problem with my Edge 800. I have installed the Openfiets map as you described but unfortunately did encounter some problems with it. When creating a route in Basecamp, it seems that some roads are obstructed or unfinished, although on the map visually everything looks fine. Pointing out the course points, Basecamp will create huge detours and doesn’t follow the track I’ve intended to follow. Last time I create a tour of 100 km and when I started it, it suddenly was a tour of 2647 km. It was not the first time I created a tour on Basecamp and I do know that you have to pin down the course points very carefully.

    I just downloaded the latest version of the Openfietsmap. Maybe that will help?

    The second problem is something I noticed after my 100 km course got messed up. I typed in the address and the edge was calculating the route. Then a straight purple line appeared, starting from my current position straight to the address. Like the Edge was suggesting to take an airplane :). I didn’t get any turn by turn directions, I just tried to stay as close to this purple line as possible. Although I did enjoy the ride, stopping every 5 km to check out the map is not something you would like to do with a digital navigation system.

    Do you have any idea on how to solve these little hiccups?

    Reply
  140. I found the solution for problem number two: not showing any turn by turn directions when navigating to a certain address. It just comes down to one setting really. Go to your settings – System – Routing – Guidance Method should be ‘On Road for Distance’.

    I am having difficulty getting nice looking maps for my 810. I would like to have my map look same as the 3rd last photo in your post. It would be the photos just before the comments.

    I have the Openfietsmap Lite loaded for my area. I have also loaded some cycle osm’s in order to have those as well. However I still do not seem to get the simplified looking map as I mentioned above.

    I am creating my routes on RidewithGPS as it seems to be the easiest to include cue points(turns, etc). I am not creating them with OSM but rather with Google maps since it has all cycle paths and main roads for my area.

    And I just followed a route this morning(in the car) and I did not get warnings for upcoming turns or a large arrow pointing in the direction of the turn.

    So in summary my biggest issue is the map. Which to have on 810 and which to enable. And the turns. By default should they not show up given the defined cue points I have in the map?

    Thanks in advance to all.

    Download times – If anyone is having an issue with when you map request will be ready e.g. “This request is #1606 in the queue. The delay is approximately 6.7 days.” I believe this is in only in relation to a custom map request. If you just ask for a pre-defined area / country without clicking ‘enable manual tile selection’ then you should be taken to a webpage where you can download the maps.

    I hope this helps.

    Has someone figured out if it’s better to have many small maps and only activate those you know cover you at a given time (e.g. for me I’d have the Pacific Northwest, then CA+UT+CO+MT to ride there, then France, etc.) or are big maps just fine? Does the size of a map influence boot time?

    Also when doing multiple maps of adjacent areas it is easy to get duplicate segments/tiles across maps. JaVaWa tools complain about that, but will an Edge 800 actually be bothered by it and botch navigation?

    I used your instructions and put a map on my Garmin Edge 800 a three years ago when I purchased. I made a new map and put that map on my Edge, which has since been updated to sw ver2.7. The new map does not come up. I reload the old map, and again with no problem the map displays. I downloaded a map made by a different source (collection of map files made 2013-11-02 titled gmapsupp.img from a usa_east folder. The map does not come up in the Edge.

    I followed all the steps, Garmin Edge 705 automatically (enabled) checked Openfietsmap Lite. I am still seeing only my local area on the Map, the map I loaded on the Micro SD card doesn’t appear at all. I even changed the name of the file as some suggested but 705 doesn’t see the file in Map at all. Card is formatted Fat32. The downloaded map is the only file on the SD card, I purchased a new card to load file on, didn’t use CNav North America NT that came with the unit.

    What am I missing? Leaving soon for Spain, I was hoping not to have to buy expensive pre-loaded SD card.

  157. Ray, your blog is now my go to for all things cycling GPS. In fact my decision last week to get the Garmin 810 was due entirely to your review and overall info about Garmin units. Of course I went through your link to Clever Training to purchase, no brainer for me and the coupon code was icing on the cake. I make my living on the interwebs and do a lot of how to videos and articles for my own branded product…I know and appreciate how much time it takes to create the content you put up on your blog.

    I am one of the “1000’s” that truly appreciates your effort to deliver top notch content…FREE. Thank-you.

    Maybe for PC illiterates you can find someone on fivver (why waste your time) do screen capture of PC file basics and hell…charge $10 for it … I think there are a lot of people getting GPS units for cycling that dont understand basic file management for PCs and with firmware updates, downloading OSMs, backing up ride date and settings from the unit etc its pretty important to get the most out of their Garmin.

    one last thing…you are one lucky dude to be married to a woman that makes insane cupcakes and is a athlete … that shop of hers looks awesome!

    I might have to put that on my bucket list… find and marry a woman that owns a store that makes gourmet cupcakes and is also a athlete…I could then die and be a happy man.

    Thanks for this clear and simple step-by-step. It literally took minutes to set up.

    I use a Garmin Edge 800 and was wondering, what are the differences between the ”Generic Routable (new style)” and the ”Routable bicycle” maps? Before stumbling on your article, I had already sent my request for the ”Generic Routable (new style)” thinking it would contain the most details/POI/streets/bike paths and have a bigger zooming and turn-by-turn navigation. After reading your write-up, i noticed that you suggest generating a ”Routable bicycle” map type. Does this mean the ”Generic Routable (new style)” map type actually contains less information/details and is less suitable for cycling?

    When I turn on the Edge Touring, I cannot access the new map nor can I see how to navigate to it from the “Tools” option.

    Great download instructions, I reviewed ALL the above posts and did not see any relating to the Edge Touring model. Thank you for your suggestions.

    Thanks Rainmaker, saved a whole heap of money and not only have UK maps but Northern France as well as I ride of there a fair bit. Instructions were easy to follow, my first two attempts failed due to the files not downloading correctly but I persisted and it worked perfectly as per your instructions on the third attempt. Thanks.

    Thanks DCR! Just got an Edge 1000 for xmas that was pre-loaded with EU maps and I’m in WA state. Instructions are flawless. Now I can stop at breweries using POI during my rides!

    Thanks for the great instructions – I couldn’t believe that Garmin would sell me an expensive GPS box and didn’t include a functional map! About as useful as a brick.
    The only point to add to your instructions is to make sure the SD card is formatted for MS-DOS. I had a 2GB card that was formatted for the Mac OS, but couldn’t get the unit to read the card. When I reformatted it for the PC, voila! Now I can ride anywhere without getting lost.

    Hi Ray! Thanks for the awesome article. I was able to follow your instructions and have come up with a set of maps that I intend to use over the next few weeks (singapore and philippines). I have a garmin edge touring unit. on inspecting the unit, it seems that no map is actually stored in the actual device. i think the NA maps are in the micro sd card. So is the process to get new maps into the device to load as simple as getting new micro SD cards, creating a garmin subdirectory and transferring the files to it; then loading the card into the Edge and turning it on? Thanks again and happy new year.

    Ray –

    Thanks as always. I also travel internationally/intercontinentally, and have found the Garmin only reads the “gmapsupp” file in its original name, regardless of what I try to enable. Rather than moving any of my maps off my SD card, I keep them named with the region on the card. When I need to enable a new map, I swap file names. I recognize this isn’t the easiest thing for everyone, but I do not always travel with my “base” computer, but can use just about any computer with a USB connection to manipulate the files on my Garmin.

    I find I probably feel the same as many of your readers with regard to my love-hate relationship with Garmin. Their hardware is probably the best out there (my 800 still works perfectly after being run over following an “incident” that dislodged it from my bike…), but the software and “user experience” can be infuriating. It would be nice if you could store a selection of maps and simply enable the ones you need vice manipulating file names… though if anyone has found an easier way to do this, I am all ears.

    The free maps stored on my Nokia phones have allowed me to find my way, especially when having to reroute because of unexpected gates. Can these be copied and transferred unto a Garmin 705?
    Failing that, can I copy My Nuvi’s (dated) USA mapping onto the 705?
    Thanks

    Reply
    • No, neither of those unfortunately. But, the Openstreet maps noted here cover the entire world (and are up to date)…and are free. So you’re still good with using Openstreet on the 705.

    Hi
    Thanks for the detailed tutorial, I’ve managed to download the Openfiettsmap Lite to an SD card no problem.
    The problem comes when I try to load a course. Previously I used a Garmin Edge Touring, and I’ve been using the same process to create courses. I create them on Garmin Connect and then send them over to the device. Once the course is loaded onto the 810, I tap on the little magnifying glass to search a destination, I select courses and choose the course I want to ride. The purple route of the course is placed as an overlay on top of the map, and the Garmin will alert when off course however it doesn’t display turn-by-turn directions. I have to keep the mapping page up to ensure I don’t go off the course. When I click on the “riding on xxxxx road” at the top to try and view the cue sheet, the message “currently no route is active” is displayed. Yet, if I go to select another course it displays “would you like to end the current course?”.

    Any ideas for a solution to this problem?

    Thanks in advance.

    after my trip, i am happy to say that the instructions worked like a charm! was able to get maps of my ride in singapore, manila and even boracay island in the philippines. i guess the only hiccup was the fact that when i synced my device to garmin connect, it only recorded activities for the last map installed. i thought it would keep the data from the previous rides but it only stored the rides/maps for the most recent map data used.

    Thanks for the clear instruction!
    I’ve bought a edge 810 last week and this weekend I wanted to go for a ride. I’ve downloaded some maps, put it on microSD card and put it in the device. At startup I stayed on “loading maps” for more then 30min without going further. Because I made a manual selection that was quite big (3giga), I downloaded a new map (only belgium). When trying with this much more smaller map, it also took a lot of time. Because I had to start with my ride, I removed the SD card and continued without it. So my questions, is this normal? How long does it take? i’ve used an microSD card of 4 Giga.

      Try creating a much much smaller map and upload that. The whole of Australia is only a couple of hundred meg – 4 gig is huge! Are you trying to upload the entire universe’s map? Keep in mind, the bigger the maps, the slower your unit will function as it has to trawl through so much information. Keep them small and you won’t have an issue.

    Awesome post, really helpful info – had a great ride through London on this!

    One quick question – is there any way of loading multiple maps on the device (i.e. for other countries, France, Italy etc.) as I am planning on doing some riding through Europe? I was wondering if you can just change the file name s and whether Garmin would pick this up, or whether you actually needed to create a custom map of Europe?

    Thanks,

    I used these instructions in 2013 when I first bought my Garmin 800, and it worked great. Recently I’ve tried to add maps for HI and CA, and both times it has not worked at all. The download and unzipping process went fine, the .img file went into the Garmin file on the SD card (right next to the successfully loaded map from 2013), but when I look for the map in settings, it only shows the original base map and the first OpenFiets map from 2 years ago. No matter where I put the file on the card, or what I name it, the system won’t recognize it. Any thoughts?

    The maps on my Garmin Edge 1000 are definitely NOT the Open Street Map ones. They’re Garmin Cycle Map EU 2014.20.

    They give some navigational problems, and Garmin have suggested that I try instead using the Open Street Map ones.

Got a little frustrating for me so I finally called Garmin and complained that after spending over $400 for a device made for cycling navigation that it does’t even come with the maps that allow you to navigate at all. They felt bad enough that they just sent me their maps for free! Catching bees with honey, boys!

    I just want to say thank you for this. I followed your directions and it worked perfectly — and not only that, it worked perfectly on my GPS, which is an Edge 605, not one of the models listed here. My 605 is pretty old, and I figured I was never going to be able to update the map on it, but now I can. Not only does this save me the $$$ to buy a new GPS, but it will keep my perfectly good GPS out of the landfill for years to come…until the battery no longer holds a charge. THANK YOU!

  223. Thank you, sir! I ran through the instructions – didn’t work the first time but I scanned the comments and noticed I needed to double check my card to make sure it was formatted as FAT32 (garmin doesn’t like exFAT apparently) Boom, dynamite. I’m in. Thanks for taking the time to put this together, it saved me a bundle on a Garmin map. Planning on sending some bread and GPS traces to the OpenStreet project.

    Maybe it was growing up in the computer age, or maybe it was that programming class in high school, or just using computers for work every day for 10 years, but I’m with you, creating a directory and copying a file in a Mac or PC environment is assumed knowledge, considering the tutorial is posted on a website.

      I ended up using Osmand version of the map on my android phone. On the ‘configure map’ setting it is possible to select the display language for place names. I’ve just rechecked on my phone and successfully switched between Chinese & English display.

      Went out after said install of basemaps. Had full on navigation. Heads up details of next turn with ‘white arrow’ direction pointer. Limited space but used further tools to the ones you have suggested to use a specific bounding box output from OSM. Also possible to gain an extra 5MB by removing further language support in the ‘Text’ folder. Was originally upset at recently buying 510 only to see 520 come out. However, thanks to your post I couldn’t be more pleased with the 510.

If you however create a tcx file (ridewithgps) and use that as a course everything then hooks up. When starting the course I get a ‘calculating x%’ notification. Once this hits 100% I’m up and running with street view and satnav like directional info. Good luck.

    LateStarter. Just re-read your post. Sorry was just about to go out on a ride at the time and was writing the above on my phone very quickly. I can see that you are indeed following a course based on your attached image. Therefore all I can assume is different is that I am on software version 3.50 see link to www8.garmin.com. There is a line in there namely ‘Made several improvements to course routing and general course experience’. I am hoping this is when the extra functionality for course routing was implemented. I’d be very interested if you get this going, please let me know. JB

    Tried to create a map using opentreetmap site.
    I get the status email but never get the completed link. Am I doing something incorrectly/?

      It can take up to a couple of hours after you get the status email before you get the link. You need to be patient. I have found that the first status update usually way overestimates the actual time. So, e.g. the first status update might say 6 hours, but then it actually only takes 30 minutes.

      Unfortunately I get the message link. It says that the map has already been created and I should have gotten an email with the download link. But that email has never arrived. I’ve tried it serveral times to no avail. It has been over a day. I think something is wrong.

      Hmmm… That is unusual. I doubt it is a SPAM folder issue since both the initial tracking email and the email indicating completion come from the same sender, lambertus@sfs4.pleiades.uni-wuppertal.de, so if you receive one email, no reason your spam detector should capture the 2nd one, but worth checking just in case.

      I created 4 maps today without a hitch.

      Here is a link to resources for ‘help’ on OSM (e.g. facebook page, google+ page, Linked in, etc):

      Hope you figure it out soon.

    Does anyone know if there is a limit to how many .img files the Edge 800 can recognize from the microSD card? I installed 3 files all of which can be seen in Windows Explorer. Each is about 3 GB on a 16 GB card. On the Edge 800 I can only see 2 of the files in Settings/Map Information/Select Map, plus the Base Map. I tried deleting the 3rd file, renaming, it to gmapsupp.img (the other 2 have different names), tried a smaller file (118 MB), all to no avail. So I am beginning to wonder if maybe the Edge 800 will only recognize 2 img files besides the base map? Any thoughts? Thanks very much

    I followed the instruction step by step. When I get that second email stating te map is ready, wen I click on that link I am taken to the page whcih lists a bunch of files, but I am not seeing the gmapsups.zip file that you referenced as an option. Not sure what to do next.

      The file name may not be exactly “gmapsups.zip”. It may be something like
      “osm_generic_gmapsupp.zip ” or some other prefix. So long as the filename ENDS in gmapsupp.zip, that would be the one. Is there nothing in the bunch of files like that?

    I just purchased a 1000 that has a Europe Base Map. I have downloaded und unzipped a base map for California. When I turn on the Garmin it gets to the screen that says “loading maps” then freezes. I have updated the Garmin software (3.10) and the California map file is on the micro sd card (“gmapsupp
    is the filename and is in a folder labeled “Garmin”).

    Send courses from iPad to Garmin Edge 800 for 30 (well spent) bucks

    I recently purchased an Edge 800 after my iPhone overheated for the 8th time while biking on a sunny day… I have seen a few posts on the web about folks wishing they could send a course from an iPad to the Edge so they wouldn’t need to lug a laptop while traveling. Here is a way to do it. It does require the purchase of a quite amazing device: link to kingston.com
    Disclosure: I have no ties whatsoever to Kingston; I do feel that they make dependable products with a high value:cost ratio.

    I researched the Kingston MobileliteG2 device when I needed a way to email photos from a digital camera while travelling. I wanted to transfer the photos to my iOS device easily. Eyefi-type cards are good for this, but they are expensive, there was a latency issue for me that caused many photos to get corrupted, and the network setup is cumbersome. The Kingston device allows you to use a fast SD card in the camera and is easy to set up. Then I thought—maybe the device could be used to transfer a gpx file from the iPad to the Garmin Edge—and I was excited to find out that it can :) So for little more than the cost of a ‘regular’ 4600 external battery charger (which this Kingston device can function as also) you get a “Swiss Army Knife” that has all the functions described in the above link. It is available for $30 from Amazon link to amazon.com

    Here are the instructions I used. While it seems like a lot, it is all actually very intuitive once you’ve done it a couple of times.

    1. I used MapMyRide in Safari on the iPad to create a route. Here is a good post on how to do this on a PC- it is similar on the iPad- just a bit more tedious, but still doable: link to spoke2spoke.com
    2. Download the Kingston Mobilelite app from the App Store onto the iPad
    3. Set up the Kingston Mobilelite (hereafter Kingston) using the excellent instruction booklet included with the device
    4. Once all 3 lights are steady on the Kingston (yellow, blue, blue), go to iPad main Settings, select WiFi, select Mobilelite Wireless to connect your iPad to the Kingston wirelessly
    5. Plug one end of Garmin Edge cable into the Garmin and other into the USB port on the Kingston
    6. Back to the iPad- find your route in My Routes on MapMyRide in Safari
    7. On the right of the screen, under Route Info, click ‘export this route’
    8. Export as GPX
    9. Download GPX file
    10. Click “Open in…”
    11. Slide top row of apps til you find “Open in MobileLite” and press that
    12. Select the route you just exported
    13. At very bottom of pop-up window, select middle icon (looks like 2 squares with an arrow between them)
    14. Select USB drive on next window (remember, your Garmin Edge is plugged into the USB port of Kingston, not the SD card port)
    15. Press Garmin
    16. Press Newfiles
    17. Press Copy
    18. Exit Mobilelite Wireless app
    19. Disconnect Garmin Edge

    Power on your Garmin Edge, and your route will be in Courses.

    Hope this is helpful to some folks…..
    Cheers!

    Hi,

    Great guide! Thank you! I have followed it successfully several time now… which has led to my question!
    I have several maps loaded, for UK mainland, Alpine region etc etc, and I have renamed the .img file to meaningful names, but on the device (Edge 810) they are all called “Openfietsmap Lite”. Is there a way to rename this? So that each map file can be distinguished easily on the device?

    Many thanks

    Thanks for this post Rainmaker!

    I was able to get the maps on my edge 810 quite fine.

    Later this year I am travelling to Germany and have booked a self guided bike tour. The tour guide has sent me all of the GPX maps, but I don’t seem to be able to upload them via garminconnect.

    I was wondering, if I add the maps to the Garmin folder, will that work? I did try adding them to the course folder, but it didn’t seem to want to copy there.

    Any idea how I can get these courses on my device and also view them on garminconnect prior to my rides by any chance?

    Thanks for the help!!

      I believe you need to copy the courses into the NewFiles directory under Garmin. The Edge software then copies the files to what it thinks is the correct directory (in this case, Courses) when the Edge is restarted.

      That is what I have learned….

    echoing Brent’s question. New 520, got the maps but not sure where to place the file to get it to load. Tried Garmin folder on the 520, New Files folder but to no avail. File is there just not read. Also no menu selection under settings to select different map files. Anyone figure this out?

      Richard:

      The Edge 520 HAS a folder named Garmin so you cannot create a new folder at the root level also called Garmin.

      Here are the things that I have tried:
      -Created a folder called Garmin within the root level Garmin folder. Didn’t work
      -Placed the file within the Garmin folder at the root level, didn’t work
      -Placed the folder in the New Files folder. Didn’t work
      -Placed the file in the Custom Maps folder. Didn’t work.

      Has anyone made this work on a 520? Part of the issue is not knowing which map database is open. There doesn’t seem to be any way to see that. Also, no way to choose different database unless I just haven’t stumbled across the menu yet.

      Thanks again.

    • So it looks like there’s been some slight tweaks in the way this is working on the final versions of the Edge 520.

      Out of curiosity, does this work:

      1) Make a backup copy of gmapbmap.sum & gmapbmap.img
      2) Delete gmapbmap.sum
      3) Copy the gmapbmap.img to the Edge 520

      Reply

      Thanks Ray. Before I do this let me make sure I understand your instructions:
      1) Copy both
      2) Delete just 1?
      3) You say to copy gmapbmap.img to the Edge but do you mean to copy the gmapsupp.img file to the Edge?

      Cheers

    • 3) Yes, meant that.

      Sorry – translating some instructions from someone in the know that sent them to me last night and I don’t have a 520 on hand at this second to triple-check myself how it is on the final firmware. Thus…this was a hail mary. 😉

      Here is how I got it to work (I hope….):
      1) Removed gmapbmap disc image file from 520.
      2) Put the gmapsupp disc image file that I made and renamed it “gmapbmap”

      Turned on garmin and it seems to work.

      Hope I didn’t mess anything up. A big benefit is that removing the installed basemap opens up a lot of room on the device.

    I removed the gmapbmap files from my Edge 520, unfortunately for some reason they have gone from the file structure, but have not freed up any space. As such I cannot either add the new gmapbmap file or replace the original files. As such zero maps at all.

    Would any kind person have any recommendations?

      Rob – I bet when you ‘deleted’ the file it was merely moved to a trash folder. Try emptying trash for that USB volume, which should really free up the space. That said, I followed the note here about replacing the “gmapbmap.img” file with the OSM version. But now I get a message about “cannot unlock maps”.

      So maps on my new 520 seem completely busted. Anyone have an idea on how to fix?

      Actually – mystery solved. It works for _some_ osm generated map files. One file I generated was 50MB, and it printed the message about “cannot unlock maps.” But if I only did most of the SF bay area (to reach 18MB) it was then happy. Yay!

    Garmin 520 first impressions & maps

    I had trouble getting OpenStreetMaps to work on the new 520 so I headed here…only mistake I made was starting at the top of the comments and reading through 300 posts before I saw to rename the gmapsupp.img to gmapbmap.img. Was necessary to delete (and empty trash) the original gmapbmap.img before renaming the new file. I made a backup of the original, but assume I probably don’t need it because it will probably get restored if I do a full device reset, but I don’t plan on finding out unless I start having issues.

    I’ve only ridden 30 minutes with the new 520 (thanks Clevertraining/DC for getting it to me so fast and at a discount!). Was interested to see how it handles overlapping Strava segments…appears to only catch the first one and ignore the subsequent ones, so I went into Strava and made sure to only put stars on the ones I want to see and made sure they don’t overlap. I also disabled a segment during the ride and when I passed it again, it still started up. Oh well, wasn’t expecting perfection out of the box.

    I can confirm the data fields are MUCH easier to read than the 510. You can also view your historical data while you are in the middle of a ride, though I’d recommend pulling over first :) That was something that occasionally annoyed me with the 510. Also, the way it handles sensors (pooling) seems much better than matching each sensor to a specific bike profile. If you pick up multiple sensors of the same type, it just asks you if you want to switch from the current one to the next one. Helps if you have them named so you can recognize which one is which.

    All in all, I’m loving the 520 after having it for only 24hours, compared to my old 510. I’ll have to get used to the buttons, but that shouldn’t take long. I should also mention that with the K-edge aero mount, I am still able to hit the bottom buttons, although they are quite close to my bars. Hope this long-drawn-out review helps someone.

    Found by Google after a suggestion from another user and using my (new) Edge1000. Instructions worked perfectly – although no email required as I could immediately download the files. Went straight on to my Edge 810 with the appropriate re-starts – necessary for Garmins to find new files – and I now have open street maps on it. Might have even saved buying the 1000 had I seen earlier, although the significantly larger screen of the 1000 makes it worthwhile.

    Hi Rainmaker, Thanks for the instructions/guide on the mapping thing, I am in the Netherlands and tried to use your process for the Zuid and North Holland provinces (several blocks). The Website indeed created the map and I managed to download and put it on my micro SD card on the E800 (using Finder MAC OSX) while I had Basecamp open and watching it for the change.

    All seemed to go well, but when I loaded the map, the top half seemed to be completely missing (hashed out). I retried to transfers but got the same result. I have just loaded another map to see if I get the same problem. Do you know if I need to do something to avoid this or when this might happen? Any words of wisdom would be highly appreciated. Thank you! Also for this excellent guide… Very good, would be lost without it…

    I’ve spend over an hour tearing my hair out, testing different SD cards, running benchmarks as I thought that is an issue with my Garmin 810 (which has its warranty just expired).
    But now, as I’ve just benchmarked my old Edge 500, I believe it’s perfectly normal.
    Of course Edge 500 has no SD card slot, but I was benchmarking transfer speeds of headunits internal memories as well.

    Thank you sooo sooo much. My new Garmin Edge touring plus never worked properly. I installed a map using your guide and it works perfectly all the time now. I also got maps for the Canary islands for my holidays too. Brilliant guide and well done for all your effort. Much appreciated. You saved me from chucking the thing in the bin…. Thanks again…

    I’m having a problem loading the OSM maps into the Edge 520. I scrolled thru all 484 comments looking for “cannot unlock maps’ error that shows on startup of the 520. I followed all the directions to the letter, and have the OSM file renamed to gmapbmap and removed the original garmin disc image file. I also tried adding the file extension in the name to see if that made a difference but no go.
    It appears that some people have success, but I’m having no luck
    Is there a work around for the “cannot unlock maps” error?
    thanks

    The downloaded file from the OpenStreetMap website was a folder called “openfietsmap_lite_tiles”. All of the img files are nested inside that folder; it appears that each map square that I ticked became a separate folder. (Perhaps that website has changed??) Thus, there is more than just one image file. How do I get this properly into my Garmin 520? Do I copy the folder with files or only each individual img file? Please advise.

    Garmin Edge 520: Help me!! I cleared the gmapbmap.img file after saving a copy. installed a new map by copying the gmapsupp.img file (35mb) and renaming it. When I went to reverse the process, it is saying that I don’t have enough memory. I now can’t install any map file at all. Please help

      Hi, yes I have the same problem. After removing the base map file when I try to copy across the new file I have created it says there is not sufficient space on the 520. The files I have tried to make are no bigger than 60MB. I have just made a smaller one (41MB) to see if that does the trick.

      I have been right through the 520s file structure and as Ray suggests it should mean that I have nearly 100MB free but if you look at the basic properties of the 520 it seems to think there is only 51MB free despite the base map file not being there. Any ideas?

      By the way, fabulous site Ray, thanks; although you’ve cost me a load of money on several occasions!!

      Chris, same problem here (purportedly not enough room to copy the file back to the Garmin). I even went to the Garmin Webupdater and re-installed the same software ver. 2.30. That did not help – I still cannot copy back into the Garmin the original gmapbmap.img file that I took out with the intention of replacing it with another map set from OpenStreeMap. Now it appears as if the Garmin has no maps . . . . If anyone has any suggestions, it would be much appreciated.

    I am a 20 year IT veteran, yet made the mistake of initially downloading the Mac OS version of the map from the open street site. 3 minutes reviewing your instructions, and I correctly downloaded the ~gmapsupp.zip file, and your instructions worked perfectly. This would’ve taken me many hours to suss out but for your very clear and specific instructions for my new Edge 520. Worked immediately, looks great, and I can only say thank you, sir, for all your hard work. Paid off for me.

    Free space problem

    I have a new 520, and have replaced the base maps (47.4MB) using your excellent directions. I have a few starred segments, perhaps a dozen, and have done 5 rides on the device. However, now trying to transfer a gpx route to the device (1.4MB), it tells me there is no free space. Mac’s disk utility confirms that, but I can’t see any large removable files. (I deleted all the language files too, but that didn’t help.) Any insights?

    Hi,

    I have followed your instructions to a “t” and the maps simply will not load on my Edge 520.

    1. Copied the base map from the Edge 520 Garmin folder to “my documents” on my pc. Then deleted the file from the Garmin folder.

    2. Selected Routable Bicycle (Openfietsmap Lite) from the website. Selected the areas (total file size: 32MB). Waited for the zip file to be delivered via email.

    3. Extracted the Gmapsupp.img file from the Zip file. Copied it into the Garmin folder.

    4. Renamed the newly created Gmapsupp.img file to Gmapbmap.img.

    5. Ejected the Edge from the pc. Rebooted the unit.

    6. Started a ride. scrolled to the map screen. NO MAP shows.

    Thanks DC, great instructions for how to load OSM maps to the Garmin Edge 520! Everything worked perfectly.

    As a new Garmin user I have only one map question. If I am out on the trail (or at the trailhead) and I want to use the device to “look ahead” to preview a mtn bike trail network before I ride it (a common use case I’d think), how do I do that? I see that I can zoom in/out on the map, but is there a way to move around on the map image and then zoom in on a particular map location? Maybe its not a capability of this particular Garmin model?

    Thanks for such detailed instructions and reviews :)
    Quick question about removing the baseman on the 520 and replacing it. I followed the instructions, but missed the bit where you said: “Note: If on a Mac, you must now empty your Trash bin, otherwise you won’t reclaim the frees space”.
    And although I’ve been uploading my rides each day and deleting them, the day-before yesterday I got a “memory full” message. Today within 5mins of a warm up for a race, I get the same message, and unfortunately nothing therefore recorded for the race. So back home, and having re-read your instructions (I use a mac) I realise I didn’t follow them! So I’m trying to undo whatever I’ve done, by reinstalling the original basemap, after discarding the replaced one to the trash (and then emptying the trash- hope it works. But I don’t really understand why you have to do this, and why won’t it work just by dragging the basemap file to the trash on the mac?

    Reply
    • The reasons behind it are more around how the Mac works than anything else, in terms of disposing of deleted files.

    The baseman that ships with the unit isn’t sufficiently detailed for bike navigation. An Open Street map is more granular, at the cost of being more local.

    Hi, First of all, thanks for the site – I have used it loads of times and it’s a joy. Specific question, I’m looking to buy a Garmin (I’ve been using the Wahoo Reflect+ with Ridewithgps turn-by-turn directions – awful, really buggy and very poor directional abilities even when i can get it to work, which isnt often). If i go this way, using a Garmin edge 1000, is it straightforward to export ridewithgps routes onto the Open Street maps and get turn by turn directions? I love the idea of looking at a new route on the ridewithgps site and then having the garmin take me round it without too much faffing. Am I hoping for too much here? Has anyone else mastered this? Thanks!

    • Colin Campbell

      The Edge 1000 comes with OpenStreetMap maps for the country or region where you buy the unit, and for me, they have been quite good when I’ve used the guidance. You can build routes with RideWithGPS and export them directly to the Edge 1000 as long as you are a premium member (I found their premium price too high for essentially that one added capability), Strava (premium, I think), Garmin Connect (totally free after you’ve paid a King’s Ransom for the unit), and no doubt MapMyRide and other sites.

      It just works for me – no problems.

      One source of disappointment is battery life while using guidance. It’s sufficient for a century (100 mile) ride, but it isn’t going to take you on an all day tour without battery backup.

      Thanks for the reply Colin. I’ve come from the world of mountain biking into road biking, just signed up for a 75 miler which will be the furthest I’ve ever ridden so that should be fine for me. Can I ask, how are the turn by turn instructions displayed – are they overlaid on top of the map, or do they just show a big, usless arrow like the Wahoo unit?

    I’ve seen that you can store maps of trails including the new Edge 520.
    Of course unlike the Edge 1000 it is not possible to navigate or set targets, but you can only follow a track preloaded.
    I therefore confirm this function. I can preload a track and then display it also seeing other streets? in this way unlike my Edge 500 I could orient myself better with reference to the other streets discharged through OpenStreet.
    I sent an email to the Garmin and they said that you can not load maps containing mtb trails and dirt roads.
    Thanks in advance for answers and best regards.

    These directions worked wonderfully. I first saw this when I was looking at upgrading from the 500 to 810 after I wrecked my 500 on a mountain bike trip. My girlfriend took care of that part for me for my birthday last year, and I’m finally getting around to loading these maps. While my riding is primarily offroad, I find that a lot of the trails I ride are in the map anyhow, and the ones that aren’t I usually have maps for anyhow. Just wish there was an easier way to load ALL of the US, as well as lower Canada. I’ll just have to reload the maps based on where I’m heading, which probably isn’t a bad idea anyhow.

    Here is my issue
    I have a Edge 800 and have been using European maps since purchased and have worked fine, played up a few times with navigation etc which I think most people have come across at one point or enough, but overall the unit is fine.
    I am currently undertaking a tour from Singapore to Chaing Mai and have been given an actual Garmin Southeast Asia Map pack as a present so ideally want to use it. Now I have taken the European card out and replaced it with the SEA one but it is saying that “the maps cannot be authenticated” but they are 100% legit from Gamrin Direct. Now when I put it into a computer all the info is there and have tried copying the files onto the european card but it still won’t have it. Garmin says SEA maps are supported on the 800 but I’m a bit worried now as I have now idea where I’m going.

When I go to enable maps on my Edge 705, I do not get the “Openfietsmap Lite”. Is this because I downloaded maps for Northern America but I am currently in Australia?

      The 1000 just has the same map as I downloaded for my old 800 (talky toaster open source). Whilst it (the 1000) is a bit smoother on the operation front on the mapping alone IMO its not worth it.

      I use the map for road navigation, its took me to the banks of Loch Lomond but thats about as off road as I get 😉 The 1000 is a bit smoother (slightly more intuitive and a more sensitive touch screen which is sometimes great for gloves but other times a pain, like today when the rain came on hard and it decided to change screen or a large drop of sweat from a turbo session). I don’t really notice the difference in screen size. Where it could be an advantage but Ive no real experience of it, the 1000 uses Glonass GPS in addition to the American’s, so locks on faster but I switch it off to get better battery life. So for what I do I dont think its a 100% needed upgrade.

    Thank you for the info! One problem, the website uses PKZip to create the .zip file for you to download. Natively, OS X (I’m using El Capitan aka 10.11 aka the newest thing out there) can’t unzip the file! You have to download a 3rd party application in order to extract the map file from the .zip file. A little annoying, but no biggie.

    Thank goodness. I’m in Japan right now and according to Garmin, they don’t have a Japan map. I heard from local bicycle shops that I could get it for free from the Garmin-Japan site, but I couldn’t find it and neither could anyone else.

    I was able to get it easily by following your instructions. Thank you so much.

    The only thing I found different between your instructions and my experience was that I did not have to wait for a map to be built, and for an e-mail telling me it was ready. I just selected Japan and downloaded it directly. Apparently, you only have to wait for the e-mail if you’re requesting a custom map.

    I’m very appreciative for this because I found myself in Japan and discovered that Garmin has no maps for this country apparently. I heard that I can download them for free from Garmin Japan, but neither I nor any native Japanese I showed it to could figure it out.

    But one problem. While I was able to download and use the map–thank you x infinity–the place names in Japan are typically in Chinese characters, and the free map transliterates these place names not into romanized Japanese but rather into romanized Chinese.

    So for example, if I want to ride to Tokyo or Kyoto–just saying famous place names–you can’t find them because the names are written however they might be called in Chinese. In fact, I don’t think even a Chinese person could figure out what the romanized names would be since they use optional characters.

    So far I’ve been taking my Garmin Edge 705 with me everywhere and tagging places as I go along, but that doesn’t help me get to places I haven’t been before.

      I today downloaded the UK map to my iMac, then clicked in downloads as instructed to open the ZIP file which created a file called gmapsupp.img. I then created the Garmin file in my new 16GB Sandisk Ultra SD card and dragged the img file over to the card. When I put the SD card into my Edge 1000 it doesn’t come up under Maps???

      Any ideas? I tried it a few times but isn’t showing up in the Garmin. All the other maps are still enabled.

      Thanks

      On the card, create a file folder named “Garmin.”

      If you double click on the file folder you downloaded it seems like you could just copy that over, but you have to decompress it first, then copy it into the Garmin folder on your card, and you’re good to go.

      Thanks. Seems to be working now on the card.

      If I leave all the maps running on the Edge 1000 do they ‘merge’ together or does it use a specific one?

    Your instructions worked perfectly on my Edge 520. My only concern is the size of the map file. The map I created is 77mb which seems a lot higher than the original map. Do you think that this would negatively affect the performance of the Garmin?

      I see you’ve just done the maps on the 520.
      it hasn’t worked for me as you can see form my post to DCR.
      any advice you can give. I’ve been over it and just can’t see what I’ve missed.
      hope you can help?!

    hi, firstly, thanks for your blog. very useful indeed, helped me to make the decision to get my 520.

    I just followed your instructions to the letter and done the process twice, but cannot get the 520 to acknowledge the new maps – in fact the base map has also gone! is there a trick to this?? after renaming the file, I disconnect the device but it doesn’t seem to have the maps. what have I missed?!

    any further help gratefully received from you and/or anybody else that knows about this stuff. FYI – running off windows.

    thanks in advance.

    Thank you very much for tutorial. But, I´ve got problem on E520. I loaded Openfietsmap, it´s working. But when trying to activate Turn-guidance, course is always shortened randomly. Look at the picture. Am I doing sometring wrong or turn-guidance doesn´t work with OSM? With Garmin base map it works with the same course. Thx.

    With the Garmin Edge 520, replacing the Garmin base map with dcrainmaker’s area detailed maps of Central Virginia caused it to generate incorrect turn directions. So, the 520 carries a trade-off. You can either have a detailed map from dcrainmaker, or correct turn directions; but not both. I’m opting for the correct turn directions. Thanks for offering the maps, and I would love to them again if you can fix this.

      That does look illogical.

      I see things like this that seem illogical, until I realize that the turn is (in your case) 1.1 miles away, and the road curves before I get to the turn. Can you go to this same place with the original maps and compare?

      Here is the same spot with the Garmin base map. The dark background is because it’s night time.

      Note the pink line off to the right in the dcrainmaker map. That is what the turn directions are following, which doesn’t even follow roads. It seems to be a random, point-to-point path that does not follow the purple route, or even any roads.

      Reply
    • Colin Campbell

      It sure looks wrong, although we cannot see the point 1.1 mi down the route, and whether there really is a right turn that would take you west. But not having any instruction for the intersection 200 ft away definitely looks like it would cause problems!

      Did things ever correct themselves with the new map?

      I created a map of the “continuous 48” and put it on my Edge 800 about three years ago. I never had problems like this. Now, I’m using an Edge 1000 with the supplied maps, and two or more updates as Garmin has made them available – they seem to work well.

      Reply
    • One thing to keep in mind is that the Edge 520 doesn’t understand/know of roads. Basically, think of it this way: Print out a picture of a map and place it on the table. Then, tell your Edge 520 to route on it.

      For it, it thinks it’s just an image. A piece of paper. It doesn’t have any electronic awareness of roads. Whereas the Edge 800/810/1000 does have that awareness.

      So when it comes to re-routing, the Edge 520 is basically just going to draw random lines. Further, when it comes to routes, the Edge 520 will depend on the creation of that route having properly assigned roadways. The reason why I suspect the generic map works, is that the roadways there were what was used for that assignment. Of course, those roads are super-wonky in that only a handful show up.

      Look at this picture. It shows, that on OSM maps, turn guidance makes turns only in the nearest area of main street (orange one), which is in base map included. Along Vostrovska street, the turn guidance line is similar to the street only for reason there is end point just few meters right of the edge of display).
      So imho somewhere in the Edge 520 have to be some file with the street (routing) data (derived from base map). which are now not corresponding with OSM. If OSM map maker will be able send us this file with map, we all will be happy :-).

      Reply
    • Jim Van Derzee

      No, the dcrainmaker map did not work, so I went back to the base map. Marek Pavlik’s screenshot below is a good illustration of the pink line that the 520 will use to generate erroneous turn directions when using dcrainmaker maps. With the base map, it uses the route.

      My main purpose for the 520 is to be able to create a safe and fun route on my laptop, then follow it on the 520. A detailed map would be nice, but I don’t really need it. I’ll just use my phone if I need to navigate off of the route I created.

    After many websites this tutorial was specificely useful for me with the GARMIN Edge 520. I thught I made the wrong choice because there was no internal SD card for maps (I didn’t pay attention to that when purchasing). Now, it’s super and it’s good to go. Simply create a new map to where I’m heading and ride. Thank you so much.

    I got routable maps working on my Epix.

    Follow Rainmaker’s instructions until downloading the zip file. Instead of the downloading the zip download the exe and run the installer. Open Garmin BaseCamp. Under the Maps menu select the map you installed the view it in BaseCamp. If that’s the one you want then open the Maps menu again and select install. Select the map you want to install on your Epix and continue. From there the process is automatic.

    Happy Routing!

    Note, in case it’s not obvious I did this all on a Windows machine. I imagine it would be similar on a mac if you download the installer for macs, but I make no guarantees.

      thanks for that it kept me trying to get maps on my epix, i have been trying to get the system to work on an iMac for quite a while now but no luck. So i went into the junk room and dug out my old windows machine and i manage to transfer some swiss maps to the epix. i live in australia but often go to switzerland walking and for meetings. so i thought i would try to put the Bernese oberland on the epix. It says its there but>>
      what i would have liked to do was transfer the swiss map from the epix to basecamp on the iMac. that way i could plans some routes. However basecamp (IMac) can’t seem to read the swiss maps on the epix so back to the drawing board

    Hey all… anyone having any problems with their Edge 520 crashing (or failing to turn on) after loading up one of these maps?

    I’m pretty new to the Edge 520, bought recently, everything was working great until I loaded this map on the GPS. It would crash after about 30 seconds, and automatically restart (even if I was in the middle of a ride, it would keep crashing and I’d keep turning it back on).

    Did a factory reset on the GPS, and all is fine now. So something tells me that it has something to do with the maps, or I’m not doing something right…

      I just had the exact same problem with my Edge 520 – frequent freezes and restarts with the OSM local maps loaded on the unit. To resolve, I didn’t reset my 520 I just restored the original basemap file.

      Did you re-download the OSM maps and give it another try? Or is the error “area” specific from OSM? e.g. one of the tiles in OSM always produces a corrupt Garmin map file?

      Reply
    • Kurt Koschnitzke

      Well, apparently OSM maps was not my problem…I am getting very frustrated with my new Garmin 520.

      Out of the box, I put OSM local maps on it. Went on one short ride (~17 miles) and it worked great. Next ride it restarted/froze every couple minutes until I turned it off. That night I removed OSM local maps and restored the factory basemap. I tested the 520 driving around in my car and it worked great. But then the next bike ride and it restarted every couple minutes again!

      I am at a loss. All I can think is that there is something loose inside that gets jarred when on the bike -vs- the car? Anyone else have this with a new 520? Anything else I should try to troubleshoot before calling Garmin support?

      Thanks,
      Kurt

    • But didn’t you say that it was fine with factory settings (no OSM), but froze with OSM?

      Unfortunately, my bet is that Garmin Support will tell you in that case that it’s something with OSM.

      Reply
    • Kurt Koschnitzke

      Sorry for the confusion. Here is the order in which things happened:

      1) I unboxed the 520 and put local OSM maps on it and went on a successful 17 mile ride.
      2) Two days later (no other settings changed on the 520) I embarked on a second ride. It was on this ride that my 520 restarted itself ~7 times in the first 5 miles of the ride before I just turned it off and went back to using my iPhone to track the ride.
      3) That night, I searched the web for a solution to the problem and found that some people said corrupt OSM maps could lead to this behavior. So I restored the factory basemap file and went out in my car to test it. I drove my car on the same route that the 520 had previously in the day restarted itself many times. The 520 performed perfectly, so I (wrongly) assumed it had been an OSM issue.
      4) Today I took the 520 out for another ride and almost immediately it was restarting itself. It did it three times in the first mile and I just turned it off.
      5) Post today’s ride, I again took the 520 out on the same route in my car and it worked fine.

      All I can think is that the jarring ride on the bike (as compared to the car) is what is making the 520 act erratically. Maybe after that first ride where it worked, the 520 developed a loose connection internally?

      I will let you all know what Garmin says tomorrow.

    • Gotycha now. Yeah, I’d agree something definitely sounds amiss. One quick thing to try:

      1) Garden test: Turn it on, find GPS, and then start recording. Just leave it there sitting still on your lawn/window/garden/whatever. See if it restarts.

      2) If it passes, keep recording and shake it a bunch, maybe drop it a few times if you have carpeting (don’t drop on hardwood floors).

      Might help narrow it down.

    • Kurt Koschnitzke

      Hi Ray, Thanks for the suggestion. It was a very good idea.

      I did conduct this test last night and my 520 “passed”. While stationary in my yard, no amount of shaking/jarring of the 520 would result in a restart.

      I then thought maybe it had to do with what sensors were connected at the time (I use heart rate, cadence, and speed) because every time I drive with the 520 in my car or walk with it, no sensors are connected and it performs well. So I connected all three sensors, started recording, and again my 520 performed well in the garden.

      I called Garmin today and had a good interaction with them. They agree that it sounds like a strange problem but wanted me to try a factory reset and see if that solves it. To be honest, I never did a factory reset (which in hind sight is dumb of me).

      Of course, I’ll let you know how it goes after reset.

      Thanks again for taking the time to help.

      While a factory reset is worth trying in some situations, it’s a bit of a nuisance. If I hit a problem on my PC, tablet, Garmin, or TV hard-drive recorder, a reboot is the first thing that I try. But a factory reset? – that results in a lot of work for me.

      Garmin Support are rather keen on suggesting a factory reset. On 1 December 2015, when I start a ride, I find that the Distance field on Screen 1 of my Garmin has become the Distance to go field. On 10 January 2016, after a lunch stop on a ride, I find that the Heading field on Screen 1 of my Garmin has become the Last Lap Distance field. Garmin Support’s response is to tell me how to configure the device. When I patiently explain that I know how to configure it (which is how I’d put the requisite fields in in the first place), they then say do a factory reset.

      I can see why they can’t offer a solution. But what would a factory reset prove? I decided not to do the factory reset and the problem hasn’t recurred since, so a non-recurrence after a factory reset would have proved nothing.

      Hi Dave,

      I do agree a factory reset is a nuisance (and that is why I didn’t try it previously) it is worth it to try and find the problem I think.

      Ray,

      So tonight I hustled home from work, performed the factory reset, and set out on a test ride. To be clear, this was a fresh factory reset: no sensors were named, no profiles setup, nothing. I paired my phone, connected the sensors, and used the default “Ride” profile.

      I had at least ~5 freezes or resets in about 5.5 miles of riding. Sometimes it just restarts in which case I have the chance to save my data when it comes back online. Sometimes the screen just freezes and I have to press and hold the power button to force a reboot and I loose any data that had been recorded.

      Interestingly, as soon as I got home from my ride, I didn’t change any settings and took the Garmin 520 on a walk with my dog. Recorded that walk perfectly. As strange as it sounds, it has to be related to the particular type of jarring that it experiences when affixed to a bike. And, to be clear, I am using a road bike on roads.

      I will call Garmin support back tomorrow, but I have a feeling the only thing left is to replace the unit. It might be rare, but at times hardware does fail.

      Thanks again for the troubleshooting help,
      Kurt

      One more thing that I would try. Do a fresh factory reset and don’t pair any sensors (but pair the phone), and go for a ride. That is one additional thing that was different between your dog walk and you ride.

    • Kurt Koschnitzke

      Hi David,

      I have actually done every imaginable permutation of with/without sensors, with/without iPhone connection, following a course, not following a course, etc. The result is very consistent: if the Garmin 520 is mounted on my bike, it restarts/freezes. If I hand carry it or drive around with it in my car, it works correctly.

      Ray and all,

      I contacted Garmin again this morning with the failed results from the factory reset trial. They promptly agreed to send me a new unit. They have in general offered reasonable troubleshooting suggestions, promptly answered their phone, and were friendly. My only complaint is that I must pay to ship this unit back to Garmin. Small complaint I know, but the difference between good customer service and great customer service.

      Of course I will post how the new unit does….or if my bike has a weird Garmin curse on it.

      Does “every possible combination” include riding with the Garmin in your pocket? This might insulate it from whatever kind of shocks it is getting. Of course, since you’re getting a new unit, the issue may be moot, but I thought I’d ask.

      Reply
    • Kurt Koschnitzke

      Hi Colin – good point and I had also thought of this. I did ride while hand carrying the 520 and it did not reset itself.

      I also mounted the 520 on my bike and instead of riding I bounced around my bike (lift the front end and drop, walked it down some stairs, etc.) and could not get the 520 to reset itself. As hard as it is to believe, something about the actual mechanics of riding caused the unit to reset itself.

      Thanks for the input and ideas guys. This faulty unit is already en route to Garmin. With luck I’ll have the replacement before the weekend.

      Cwilly,

      I have the exact same problems you are experiencing. I downloaded the better mapping (40mb ish) and a route off Strava (tcx file) and it crashed on loading it then got stuck in a crash/reboot loop. The only way to stop it was to connect to a computer and remove the course. Today, I put the original mapping back on and did a test route in the car and it was fine. However, I didn’t have any of the 4 sensors attached (Radar, HR, Speed & Cadence) I am hoping that switching back to the original mapping has solved it but I remain unconvinced. Such a shame. I “upgraded” from a 510 but I regret it and I sold my 510 to a friend!

      Hi guys,

      Just a brief update on my 520: The new one Garmin sent works on my bike! My first one must have had some kind of hardware issue…

      I have connected all sensors, tried a course, used Strava Live Segments, etc. All functions work.

      The only thing I HAVE NOT tried yet is to upload local maps again. I am a little gun shy…
