How to: Install Free Maps on your Garmin Edge

DSC_4280

Last week I published a piece on how to install free maps on your Garmin wearable, which was a tweaked update of my six-year-old post on how to install maps on your Garmin Edge devices. But as promised, I’d be refreshing that old Edges-specific post too – which is what this new post is all about. It’s almost identical to last week’s post and the one six years ago, except specific to the Garmin Edge series because frankly it’ll help people in Google trying to find Edge-specific instructions.

Things have certainly changed in the Garmin Edge world in six years – most notably that all of Garmin’s mapping capable Edge devices now actually come with detailed maps for the region you bought it in. Thus if you buy an Edge device in the US you’ll have North American maps, and if you buy it in Spain you’ll have European maps, and if you buy it in Sydney you’ll have Australian/New Zealand maps. Detailed maps too – not the old and useless ‘base map’ junk.

But what happens when you traveled outside your region?

That’s when you were back to the base junk. That so-called base map has virtually no detail in it. It might show a single dot for the entire city of Paris, or perhaps one highway leading into it. Certainly no usable streets or geographic landmarks.

Fear not – I’ve got you covered! You can easily download free maps on your Edge for when you travel. Quick and simple, and while the instructions might look long, the entire working time is probably under 2-3 minutes for most people. I just include a lot of pictures/text to make it super-clear.

I myself often use the freely downloaded variant I describe below (because I live in Europe, but often buy my units in the US). Or, for the European units I have when I travel to the US/Canada, like two weeks ago. And thousands of you every month do the same following these previously published steps. With that, let’s get into all the supported units and requirements and a few minor caveats below.

Requirements/Caveats:

DSC_4267-2

While this post probably looks long, it’s mostly my attempt at answering any questions ahead of time. In reality the entire process is super quick and easy. I’m just overly thorough in my screenshotting excitement. The actual active time for you to do this is like 3-5 minutes tops.

You must have a computer – Mac or PC (or even Linux). You cannot do this from an iPad or such. It’s technically possible to do it from an Android device with the right cables, but you’re on your own for that!

As for compatible devices, here’s the list of devices this will work on. It also will work on most of the handheld type outdoor devices too. If it supports Garmin maps, it’ll support 3rd party maps.

Compatible Bike Computers: Edge 520 Plus/530, Garmin Edge 705, Garmin Edge 800/810/820/830, Garmin Edge 1000/1030/Explore/Touring variants (the base Edge 520 is technically compatible, but only has a sliver of space on it, like, enough for one city), and the Bontrager Edge 1030 is totally fine as well.

Compatible Wearables: Garmin Forerunner 945, Garmin Fenix 5s Plus, Garmin Fenix 5 Plus, Garmin Fenix 5X Plus, Garmin Fenix 5X (non-Plus), Garmin Epix (RIP), Garmin Descent MK1, Garmin MARQ Series, Garmin D2 Delta PX

Now you may be asking yourself, ‘What if I have a non-Garmin unit? Will it still work?’ – and the short answer is basically no. There may be some 3rd party units that work with these maps, but nothing major. Plus, many other competitors like Wahoo, Stages, and Sigma simply make it easy for you to download maps without all this fuss.

Optional: Micro-SD card: If you’ve got an Edge unit that has a micro-SD card slot (namely the Edge 705/800/810/1000/1030/Touring/Touring Plus), you can place the maps on there instead to save space. More on that in a minute.

Finally, since I know some of you will ask, the following are most definitely *not* compatible. And the reasons are simple: They don’t have the storage, or they don’t have the processing power to handle maps. The ship has sailed on all of these (read: they’re definitely not getting map support),

Non-Supported Bike Computers: Garmin Edge 20/25/130/200/500/510, and probably a few really old others.

Non-Supported Wearables: Garmin Forerunner 15/20/30/35/45, Garmin Forerunner 225/230/235/245, Garmin Forerunner 610/620/630/645, Garmin Forerunner 735XT/910XT/920/935, Garmin Fenix 5S/5 (non-Plus, non-X), Garmin Fenix 3/3HR, Garmin Fenix (original), Garmin Vivo-anything, and countless others. Consider this just a ‘starter list’ of non-supported units.

Note that while Garmin would prefer you buy the maps from them, they actually go out of their way to allow you to download free maps from 3rd party providers. They simply note that it’s unsupported (but doesn’t void any warranties or such). Meaning that if the 3rd party map data isn’t perfect, it’s not their fault. But here’s the dirty secret: It’s the same underlying map data.

Last but not least – note that Garmin does add ‘special sauce’ to their maps – most notably what they call ‘Trendline Popularity Routing’, which is basically a variant of heatmaps. The main use for this is when you ask the device itself to create a route on the fly (such as roundtrip routing) that it leverages heatmap data to give you routes that people use more often. However, this is only applicable if you create/re-route on the device itself. You can still take advantage of that concept by simply creating the routes on Garmin Connect or Garmin Connect Mobile first, which will use that same data from the cloud.

For virtually all of Garmin’s maps included on Edge/Forerunner/Fenix/MARQ series devices, the base map itself is OSM (OpenStreetMap). What differs is some of the special sauce Garmin adds atop it (like heatmap type data), as well as the exact layers Garmin does or doesn’t display (how it looks, but also things like topographic lines).  In addition, there are some slight nuances to how the maps look in terms of exact styling. You’d never know unless you had the two side by side, which you’ll see below. At left is what the default Garmin maps look like, whereas at right is what the free OSM maps look like (the right unit is simply rotated 90°, because that’s the direction the unit thinks I was going):

DSC_4274

I find the shading/clarity of the Garmin maps to generally be better/optimized. But both are perfectly functional. However, you also won’t get topographic contour lines when using the free maps. Technically speaking you can download them and merge them together, but that’s beyond what I’m going to cover here.

Of course, I think it’s time for Garmin to move onto the Wahoo & Sigma model of making it silly easy to download maps from other regions. Or heck, at least make it cheap. Charge me $10 per region (or even country), allow me to select the regions via my smartphone app – and then go and download the maps via WiFi (Wahoo is the same process, except free). I’d happily pay Garmin $10 with a streamlined mobile-first strategy to get the heatmap and related data from them.

Part 1: Downloading the Maps:

This entire post is ‘made possible by’ OpenStreetMap, which are free community-driven maps.  OpenStreetMap has 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 OpenStreetMap.  Now, it’s literally as easy as 1.2.3. Seriously, you can do these clicks below in under 15 seconds.

Also – before I forget to mention, if you’re on an Edge 530/830, then the Trailforks mountain bike trail overlays are actually totally global, so you’ve already got the entire world in your pocket no matter which country you bought it in, and this won’t negatively impact that one way or the other.

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

image

Note that every once in a while that website goes down – as if someone didn’t put enough coins in the slot. It’s a community-supported page after all. I’d strongly encourage you to donate occasionally (even just $5, it saved you like $100 anyway). I do. If the site is down, you can use another site here. The downloading steps are slightly different (select Garmin BBBike as the format, Map type OSM Mapnik), but ultimately all basically the same. I have no relationship to either site, it’s just what I’ve used for a long-long-long time now. (Note: I’ve added some more sources at this section for cases where you might want something a bit more unique/specific.)

Once the page loads, you’ll want to select ‘Routable Bicycle’ as the map type.

image

Next, you’ll select the region/area of maps you want. If you simply select a pre-defined area (like a given country/state/province), then the site has already premade these for you, so they are instantly available. Kinda like picking up sushi from the case at the grocery store (except less sketchy). Whereas if you want something custom – perhaps across multiple countries/borders, then you can choose to create a custom map set.

If going for the preset sushi, 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. You’ll see that it automatically selects the coverage area in the map below.

image

If you don’t need anything custom, then just click ‘Download Map Now’:

image

That’ll bring you to this page. Select the one that the little MicroSD card icon next to it. DO NOT select the Windows, Mac, or Linux ones. It doesn’t matter what computer you’re using to download things, always-always-always select the one with the MicroSD card icon (also titled ‘GMAPSUPP.ZIP’ appended to the end of it).

image

Download and save that somewhere handy on your computer (like your desktop) and skip ahead to the installation section!

[Again: Skip ahead to the ‘Installation’ bulleted section if you’ve just downloaded your map!!!]

Whereas if you want to roll your own custom map with added areas, then you’ll select the checkbox titled ‘Manual Tile Selection’, and go from there. As a pro tip, if you’re just adding a bit more territory to an existing predefined set, then start by selecting that first, then checking the manual option. As you can see below, I started with the Netherlands, and then I checked the box and added a few more map tiles from Belgium/Germany/France onto the Southern portion of my Netherlands map:

image

Once you’ve selected everything you need to select, then put your e-mail address in the little box and select ‘Build my map’:

image

The reason you need to provide an e-mail address is because you go into a queue for the server to create your map. Like waiting for your name to be called at the DMV, except, more efficient. Here’s what it’ll show a second later:

image

And sure enough, just as it says I’ll instantly get an e-mail with my status:

image

And a few minutes later I get another e-mail with the download link saying it’s ready. Usually that’s all it takes. I don’t think I’ve ever had to wait more than 10-15 minutes.

image

Just like with the non-custom ones, select the one that the little MicroSD card icon next to it. DO NOT select the Windows, Mac, or Linux ones. It doesn’t matter what computer you’re using to download things, always-always-always select the one with the MicroSD card icon (also titled ‘GMAPSUPP.ZIP’ appended to the end of it).

image

And again, remember that there’s a ‘Donate’ button on that site (I have no affiliation with it). Obviously, good karma dictates that if you find their (free/community-hosted) service valuable, sending a couple of bucks their way is probably wise – especially given how much money you’re saving. Plus, it’ll probably make that map creation bit go faster for custom maps if they get more support.

And finally, if you want some other map sources, a number of DCR commenters have listed their favorites, which I’ve included in here. All of these maps basically start from OpenStreetMap, and then add details atop them. The main one I linked to above is just one I consider pretty trustworthy and more global in functionality. Whereas below some have specific areas they specialize in (and may show more details for those areas), or have specific focuses (like perhaps better mountain bike detail):

– Topo-included map source: Frikart.no
– Topo-included map source, also POI’s have opening hours: OpenTopoMap.org
– Topo-focused maps that are also recommended for Africa: GMapTool.eu
– Cycling maps specialized for Netherlands/Belgium/Luxembourg with more detail: OpenFietsMap.nl
– Mountain-biking focused maps: Openmtbmap.org

Again, the above-listed maps are totally optional – and just additional sources.

Part II: Installing the Maps:

Installation of the maps is super easy. All you need to do is put the file in the correct folder and you’re good to go. However, if you need to temporarily remove your maps, because you’re tight on space, see the optional Part III below. Most of the units we have here have enough space to add other region maps without having to clear-cut first.

To put it into context, the Garmin default map data sizes (including some cycling-specific things) are roughly as follows (the maps you’d get by default for the region you purchased it in):

North America: ~5.6GB including topo data
Europe: ~6.7GB including topo data
Australia/NZ: ~2GB including topo data

And space-wise, you’ve got the following amounts of space on each device (minus the space required above for your base maps, plus a tiny bit for any courses/activities/workouts/etc…, usually 0.1-.3GB):

Garmin Edge 520 base: 0.05GB free (just enough for one city or a bunch of farmland)
Garmin Edge 520 Plus: 16GB
Garmin Edge 530: 16GB
Garmin Edge 810: 0.05GB free (but uses micro-SD card for maps)
Garmin Edge 820: 16GB
Garmin Edge 830: 16GB
Garmin Edge 1000: 8GB (plus micro-SD Card capable!)
Garmin Edge 1030: 16GB (plus micro-SD Card capable!)
Garmin Edge Explore: 16GB

So you’ll want to do simple math to see if everything fits. For context, the download size for the Netherlands from the free maps is 0.37GB (337MB) – so pretty small. France is ~1.4GB. Again, should easily fit. But if you’re tight on space, you can always follow the custom instructions above and take a prepackaged map like France and make it smaller by removing areas you don’t need (if you’re staying in the Alps, you don’t need the entire Western portion of France for example).

If you’ve got one of the units above with a micro-SD Card slot, you can follow the exact same directions, just stick the maps in a folder called Garmin on the micro-SD card. You can pickup a trustworthy 16GB card for a mere $5 on Amazon (Reminder: When purchasing micro-SD cards on Amazon *always* ensure that it’s both shipped from and fulfilled by Amazon itself, not a 3rd party.)

In any event, let’s install things. First, connect your Edge device to your computer using the USB cable it came with (since that allows transfer for data).

DSC_4261

Go grab that file you downloaded (openfietsmap_lite_gmapsupp.zip), and open it up (just double-click it). This is what you’ll see inside:

image

Then select that file and then select ‘Copy’. Now simply paste that into the ‘Garmin’ folder on your watch. Do NOT copy/paste the entire .ZIP file, you need the file inside the zip file (like you see above). It’s called gmapsupp.img and needs to go into the Garmin folder on your device.

image

Once it’s done copying, you should now see that file sitting in the Garmin folder. The names will be similar, but it’s the one ending in ‘supp’ (like ‘supplementary’):

image

And with that, you’re done.

Side note: Need to have two extra downloaded maps? Simply append the country name to one of them to make it unique. Such as ‘gmapsupp-france.img’ and ‘gmapsupp-netherlands.img’.

image

It works perfectly fine.

Part III – Optional Space Savers Edition

This section is skippable unless you’re a hoarder and need to find a way to save some space on your device to make way for other maps. I mean, you might not be a hoarder, it might just be that times are tough and now you’ve got more maps than you know what to do with. As noted in the previous section, the maps that came with your device can take up a bunch of space. And if you’re headed somewhere that also has a big ol’ map, then you might need to temporarily offload the original map. Though again, that’s pretty unlikely with any of the half-way recent units. Seriously, there should be almost no reason to do this section.

First though, before you do so – consider going with a smaller map. Meaning, if you’re going from the US to France, and only need to ride in Paris – just download Paris only, and not all of France. Or if you’re going on a European trip to the Alps and thus think you need France, Germany, Italy, Switzerland, and Austria because that covers your entire Alps region, try instead just downloading a bunch of squares covering the alps using the ‘manual tile’ mode. Like this (my selection below isn’t perfect and definitely overshot a bit, but you can spend the extra few minutes to get it just right):

image

But, if all else fails – no biggie, taking maps off the Edge is super easy to do. I strongly recommend though *not* deleting them, and instead just doing a move to your computer hard drive for later. Think ‘Cut’ and ‘Paste’, not ‘Delete’.

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
2) Plug-in your Garmin Edge to your computer.
3) Within the Garmin folder on the Edge, you’ll find a bunch of .IMG (image) files. These are the pre-loaded map and elevation files. It can include any of the following:

A) gmapbmap.img (base map)
B) gmapdem.img (Digital Elevation Map, it’s per-region)
C) gmapprom.img (pre-installed map file)
D) gmapprom1.img (another pre-installed map file)

You could perhaps have additional gmapprom #’s as well, if so, grab it. You’re basically looking for the large files to make space. See the big file sizes below?

image

4) Cut and paste all of the above .IMG files to somewhere on your computer (create a folder called “My Garmin Maps” or something, just don’t delete them).
5) Copy the gmapsupp.img map file you downloaded into the \Garmin folder on your Edge (or, if you’re unsure, simply go back to “Part II: Installing the Maps” above and complete as normal. If you want to help yourself remember which is which later on, simply rename gmapsupp.img to something like gmapsupp-france.img or after whichever country you’re going to. You can name it anything you want – like gmapsupp-dcrainmaker.img and that’ll work too.
6) There is nothing extra you need to do on the Edge itself as far as configuring maps – it’ll happen automatically, so you can ignore Part 3 of the instructions. You’re done, go outside and ride!

And hey, there’s a bonus to using this hoarder’s route – you got the express lane for installation instructions. Just remember later on that when you get home you’ll need to put back the map file from your computer onto your Edge device. To do so, simply copy the files from your computer back into place it into the Garmin folder on your Edge and delete the gmapsupp.img file you added.

Part IV: Using the Maps:

DSC_4282

Actually, there’s nothing you have to do here. Once you’ve installed them they just work. If you haven’t added the map data page to your device, go into the activity profile of your choice (Settings > Activity Profiles > Choose your Activity Profile> Data Screens > Map>Always

DSC_4262

However, in the event you want to turn off the downloaded mapset for some reason, it’s pretty easy to do (and you can always delete that single supp.IMG file if you need the space after your trip.

To disable a given map though, go to Settings > Activity Profiles > Choose your activity profile > Navigation > Map > Map Information/Select Map > Enable/Disable the map that you just loaded. You can see below the Openfetsmap Lite-NLD, which is my Netherlands map, and below that my French map I added for France. While above it is the stock Garmin maps, in this case. By pressing the select button, it’ll turn on/off the different maps. Super easy.

DSC_4263 DSC_4265

And in fact, as I mentioned earlier – for Edge 530/830 users, you can actually see the global Trailforks map listed in there above (and if you really wanted you can toggle it on/off). Or you can see it listed when you connect your device to Garmin Express (once you’ve activated it once, which is free). It covers you no matter where you go:

image

And that’s it! You’ll be able to use these maps as normal. That includes things like elevation details for courses, planning between points, points of interest, specific addresses, and round trip routing. Enjoy!

As always, thanks for reading. And if you found this post helpful – consider becoming a DCR Supporter, I appreciate it!

    Great instructions as always Ray
    Is it possible to download entire continents such as North America etc or even just the USA in its entirety rather than having to select all the squares manually?

    • That’s a good question. I don’t see/know an obvious way to do so with link to garmin.openstreetmap.nl, and I tried BBBike.org too – and that limits you to 512MB for a custom boundary. Maybe someone else has a trick – I’d love to hear it!

    • William Cruz

      I had the same problem many moons ago when the first post on how to do this went live, being the software developer that I am, I ended up creating my own maps using OpenStreetMaps as my base and a custom TYP file that creates highly detailed maps – I host a server with pre-compiled maps of many parts of the world and I try to do a refresh every 30 days more or less, would it be OK to post a link here?

  2. macnuts

    Nice update thank you.
    I’m going to replace Garmin Europe map with OSM or omtb map counterpart as the Garmin’s map lacks some crucial paths in my area. I know that Garmin’s map will be updated eventually but I am not patient enough to wait for it to happen.
    My device is Edge 830 so I will just copy new maps, then disable Garmin Europe map for activities.
    There are Garmin DEM and Garmin Geocode maps besides Garmin Europe.
    Do they work with Garmin Europe map only? Will I have to disable it too or will it work with OSM/omtb map too?

    • You can actually toggle the DEM map separately. So you could just add the OSM maps in there as you want (should have plenty of room for both), and then just got into the menus and toggle which layers you want, including (or not including) the DEM map.

      Based on a quick test I did last night (with a secondary Euro-only unit doing exactly what you noted), it seemed to be fine doing DEM + OSM. But it’s honestly tough for me to tell when Amsterdam is basically 0m +/- 3m. 🙂

    • Meredith

      The DEM map should work with whatever road maps you use.

    • macnuts

      Thank you both.
      It worked for me. Garmin’s DEM map is used with any of my custom map. The easy way to check it is to enable shaded relief in map visibility options.
      I’ve got omtb DEM for my region and it works well too.

  3. Alexander Momberger

    Hi Ray,
    thank you for all the Information, but I DO have a question for you:

    The Fenix 5+ introduced a feature called “automatic Elevation Correction”. The idea is that when starting an activity, the Watch uses the GPS Signal & the underlying map to calculate an Offset correction between the air-pressure and the Elevation. Most Garmin watches do that. The new trick that the “automatic Elevation Correction”-Feature does, is a periodical recalculation of the Offset DURING the activity by compairing the Barometric-Measurement to the map’s Elevation data.

    1. question: Do the OSM-maps have the same Elevation information like the Garmin-preinstalled maps or is the “Elevation-map” an add-on to the Garmin-osm-maps?
    2. question: does the “automatic Elevation Correction”-Feature still work, when I’m using the non-Garmin-preinstalled osm?

    Could you maybe test that Feature when you are in the alps? Maybe you could use your fenix 5+ with that Feature activated and compare the measured Elevation gain to the data recorded by e.g. your FR945 with that Feature being deactivated.
    I would LOVE to see if the “automatic Elevation Correction” actually works!

    Thank you in advance.

    • Yup, I’ll give that a poke. I was curious myself about something semi-related to that as well.

      I’m hoping to be down in the Alps next week, and then for sure again the week after.

    • Meredith

      OSM Maps don’t have elevation data. Garmin road maps don’t have any elevation data. The DEM map is for the elevation data. The DEM map should work whatever other maps you have installed.

    • Brian Reiter

      The gmaptool.eu maps definitely do include DEM data. There are routable topo maps available for everywhere except Europe. I have used the Southern Africa, Southeast Africa, East Africa and Southwest USA maps both on fēnix 5X and in Basecamp. They are very high quality.

      It looks to me like the openfietsmap.nl “full” versions in Europe like the BeNeLux+Germany and Alps maps for example do include DEM data. I suspect it is just the worldwide “light” versions that neither include DEM data nor TOPO lines.

  4. ste kam

    When i go into active maps for an activity i have multiple active maps ?

    why ? is there any purpose or added value to have multiple ones ?

    should i keep only the OSM cycling active ? In that case will it be used for rerouting ?

    in case multiple are active which are the one used for re-routing ?

    • For me, I get funky things when I have multiple overlapping maps (of the same region). On one test I did, the world just ended blank.

      If you’ve got multiple maps of differing regions – no issues.

    • ste kam

      and what about the routing ?

      could the osm cycling be used as routing and rerouting maps ?

      how would you compare quality wise, the osm maps and garmin maps ? why would we have to do that if all garmin maps are OK ? 🙂

  5. Cyrille

    Hello and thanks,
    Silly question maybe, what is the use of dowloading a free map on my Edge 820 which already has got one?
    Are the ones you mention more precise? It looks you are saying no (in terms of rendering) so really I was wondering.
    Thanks!
    KRgds,

    Ray,
    Any idea if Garmin is planning on updating their integration with OSM in the web version of Connect? The current implementation is horrible. No contour lines, missing road names for secondary and fire roads, blocky trails. Just terrible. Looking at connect.garmin.com and openstreetmap.org side by side in a browser is night and day. The maps on the edge device actually look better than the maps in Connect!

    The google maps overlay looks a lot better, but google doesn’t have anywhere near the depth of mtb trails as available with OSM. And while neither have contour lines in Connect, openstreetmap.org will show contours with the Cycle Map overlay. I can’t be the only person that knows how to read a map and wants contour lines as a key bit of information when routing a mtb ride.

    • Meredith

      OSM doesn’t have any contour/elevation data. Contours come from other sources and have to be merged into the data from OSM to create a map with them both in. Or you could create a separate contour map and display it at the same time as the normal map to see them when looking at the map display.

    • cycloscott

      OSM most certainly does have elevation. It’s in the ‘Cycle map’ layer.
      Take a look at the OSM version… link to openstreetmap.org
      vs
      link to connect.garmin.com

      Note that in Connect, the default Google map layer LOOKS far better than the integrated OSM layer, but is missing trails. Whereas both look like ass compared to the ‘cycle map’ layer on openstreetmap.org

      Also note that there are trails that are missing on the Connect OSM layer compared to the actual source on OSM. (Aligator Lizard, and Bunny)

    • Meredith

      Openstreetmap doesn’t have any elevation data. I have edited the maps (to fix issues I have spotted) and when you edit the map you can see it definitely does not contain any elevation data.

      The cycle layer you see on the openstreetmap website is actually created by opencyclemap. The opencylcemap website has the source of the elevation data in the credits – NASA SRTM elevation data which is freely available for anyone to use. Opencyclemap uses OSM map data for the roads etc.

      See link to opencyclemap.org

      It takes a few days for edits to OSM to appear on opencyclemap as it is only updated every few days as well.

      I would expect Garmin’s OSM maps on connect to be out of date as they will likely only refresh them when they release new maps for their GPS devices.

    • cycloscott

      Fine, let’s be pedantic about it. Openstreetmap.org doesn’t –include– the contours, it only –displays– them.

      Interestingly enough the same trails that I mention NOT appearing on connect, ARE displayed on the Edge device. So connect is behind devices for some reason. And at least for my 530, the maps haven’t been updated for weeks. Also, those same trails appear in the OSM ‘standard’ layer, so it’s not an issue of the layer. –They’re still pretty blocky looking though.

      And my primary issue remains. The OSM maps on connect look like ass. One would think that a company that is chasing cyclist dollars would have a far better integration with openstreetmaps, especially the ‘cycle map’ layer.

      The google maps layer may be fine for road rides, but it sucks ass for mtb trails and we have to rely on the OSM option. Unfortunately the connect integration is terrible and absolutely needs to be addressed.

    Re: “Optional: Micro-SD card: If you’ve got an Edge unit that has a micro-SD card slot (namely the Edge 1000/1030), you can place the maps on there instead to save space. More on that in a minute.” Change “1000/1030” to “800/1000”.

    • It’s actually all of them. Also the 705 too, but I figured they were older so decided to clip it there. But good idea to include the older ones too.

    • Paul Toigo

      Well, yes, the 1030 will accept a micro-SD card too. IIRC, it has enough internal memory that is a non-issue such that I haven’t bothered putting one in mine.

    Trailforks also has packaged maps for Garmins.

    I’ve also used to Velomap.org ‘packaging’ of the OSM data quite happily.

    so, presuming we can get the Australia map onto the Edge520, what will it look like on the screen? detailed maps or just a breadcrumb still?

    • It’ll look like totally legit maps – identical to that of the Edge 530/830/etc. Only difference is that you aren’t ‘routing’ atop it, rather, still breadcrumb trail atop it. Still, it’s super useful (I used it a bunch that way in the Alps a few years ago).

    Great writeup Ray. Just wondering how I can tell what maps I have on my device currently, and where these end?

    Specifically, I bought my device in the UK and want to know whether my maps cover all of Europe, just the UK, or UK + some of europe?
    Thanks!

    • Any purchases in the UK cover all of Europe, inclusive of the UK.

      This handy link shows which maps are what: link to garmin.com

      Anything bought in the UK is loaded with the map called ‘Full Europe’, whereas anything bought in North America is loaded with the map called ‘North America’.

    I still keep getting “Unable Authenticate Maps” error on every start of Garmin Edge 1000 after putting these maps. Any ideas?

    • That’s odd. Did you remove the older maps, or they still there? To me that sounds like something is going wrong with the existing Garmin maps.

    • A.

      Yes, I have reinstalled base map via Garmin software and added new maps. Will try factory reset one day 🙂

    • Paul S.

      That was my first thought. The other is: did you follow Ray’s instructions exactly? The maps you’re putting on your device are .img, and not .gmap or .exe?

  12. paulio

    Thanks for this.
    Since Garmin Express for Mac is broken and cannot handle the latest map updates properly, I’ve had to use this guide to install some others. My and other peoples EU maps have just vanished after *updating* them (and waiting 5hrs download time in my case).

    I kinda need them now for a tour around Europe, not ‘some time in the future’ Garmin. Thanksabunch.
    ” We are working on a repair in a future Express update” …. sounds like they’re in a real hurry.

  13. Eric W McMinoway

    I have an Edge 1000, are we still receiving map updates, or should I use this method to update maps?
    Thanks.

    • I would continue to use the Garmin maps. The main reason to use this is if you travel outside the region you have maps for.

    • Paul S.

      I just checked, and the map on my 1000 is Garmin Cycle Map 2019.10 and the map on my 830 is also 2019.10. I can’t imagine that Garmin would ever stop updating the maps on older Edges that use the Cycle Map.

    • Maik

      I prefer this maps over the Garmin maps even where the detailed Garmin map is installed. I very seldom use routing, but quite often I use the map during bike rides to make spontaneous decisions where to go next. In this maps here
      1) you can see if a road is paved or unpaved and get proper information of which quality the unpaved road is.
      2) official bike routes are marked, so I can spontanously decide to follow a bike route with no need to download it.

      Both functionalities I miss in the Garmin maps.

  14. jack

    FWIW – recently discovered the ‘Komoot’ app which allows point to point route creation on mobile devices and pushes straight through to garmins. I’ve got an edge 530 and works well

  15. If I want to download a base map to my PC and then map rides on the PC and then transfer these to my Garmin, which of the four possible destinations listed early in the article do I select.

    Hi Community,

    Anyone has recommendations for free Garmin maps for automobiles. I have a Garmin (Nuvi 57LM) that I bought in US. I plan on using it in Europe, but don’t want to pay $99 for Garmin’s European map. Ray had suggested to use the offline Google option and use with the phone but when I tried, it appears as if it is for point to point direction. It also takes a lot of memory in my iphone. I’m looking for regional maps. I’ll be in Spain. Any suggestions? Thanks.

    Ray,

    Thank you for the post. I already took care of my Garmin 1030’s Europe map.

    • Meredith

      You can use the same place that Ray uses above to get maps for your car satnav.

    • JOrrego

      Meredith,
      Thank you for your reply. Which one specifically from the list below and have you tried it?
      Generic Routable
      Generic Routable (new style)
      Routable Bicycle (Openfietsmap Lite)
      Generic Nautical (non-routable)
      Transparent overlay with elevation contours

    Hi DC, I have a hand me down Edge 800 which I am trying to update the very old map, it does not have any maps in the Garmin folder of the built in memory, just one .img file (gmaptz.img).

    The SD card has several maps (gmapsuppBENELUX.img, gmapsuppDE.img, gmapsuppLUX+.img), however when I go into Menu>wrench>system>map>map information select map> i only have 2 maps called “openfietsmap lite” and “openfietsmap lite (DEU)” which i cannot find in the device, nor select the maps that I can see in the device when it is connected to my pc?

    • HI David-

      I suspect you might not be looking in the right place. There should definitely be a Garmin folder, even on the older Edge 800. When you load it in your computer, you’ll see both the MicroSD card and the Garmin unit itself show up. Do you see both? And if so – do you see a Garmin folder in either?

  19. Mark

    Can someone please give me a yay / nay on the following:

    This will work on a Garmin etrex ? I read this sentence as a straight Yes – “As for compatible devices, here’s the list of devices this will work on. It also will work on most of the handheld type outdoor devices too. If it supports Garmin maps, it’ll support 3rd party maps.”
    Google seems to confirm this is a goer

    My use case – buying an etrex in Australia, using the preloaded maps for bikepacking/touring and general bushwalking here. Later side loading maps for Japan and parts of Europe, to do the same sort of thing there.

  20. Stefan van Kasteren

    Hi Ray, are you sure that if you download parts of for instance The Netherlands that you get the second mail in 15 mnutes as I was using via your six year old post this Open Maps last June but I was the 15000 user to wait in the queu…

  21. youpmelone

    This all is summed up easily. Use velomap.

    • cycloscott

      Velomap is only an option if you’re routing on the device. Routing through connect sucks ass for mtb trails. Trying to do it via connect on a phone is even worse.

    • youpmelone

      cyclescott I am lost.
      link to velomap.org load it on the garmin and be done.
      Same goes for MTB.

    • Paul S.

      cyclescott is talking about the OSM maps on the Garmin Connect web site, not the ones on the devices. And he’s right, there are trails missing there. In particular, I looked for a trail that I hiked a couple of months ago to retrieve the keys that dropped out of my Camelbak during a stop on an MTB ride. That trail isn’t on GC but is on the Garmin maps on my 5+ (and on other OSM maps). For some reason, the OSM based maps on the GC web site are incomplete (and awfully ugly).

    • cycloscott

      What Paul S said. The maps on the Edge aren’t horrible, although I’d like to see contours as well for rides where I’m just winging it out on the trails.

      The big issue is Garmin Connect when creating routes ahead of time. Recently did a mtb race in Oregon and I wanted that route loaded so I could see the climbs that were coming up. The google maps layer in GC didn’t have the singetrack trails. The OSM layer DID have the trails (albeit super blocky), but didn’t have the fireroads labeled. Interestingly enough, once I sorted it out and loaded it on the Edge 530, it DID show the fireroad names while navigating.

      Take a look at these:
      GC with the OSM layer enabled to see the trails…
      link to connect.garmin.com

      OSM (cycle map) for the same area…
      link to openstreetmap.org

      It’s not even close. Missing trails, no contours, super blocky. Garbage. In effect, for mtb riding, you almost need to know the trails before you can create a route in Garmin Connect.
