Maps for Garmin based on OpenStreetMap

Urban map

What can you do with the maps?

Maps can be installed on Garmin GPS's, as routable maps that will give you turn by turn instructions to go to a given place (depending on device's specifications). It can also be seen in your computer, where you can calculate your routes, using MapSource or BaseCamp Garmin software, or the open source program QMapShack. With the topographic and DEM maps you can also calculate profiles for your routes.

Android Maps can be used on many mobile and desktop apps, such as OruxMaps, Locus Map, Cruiser and much more.

Viewing the maps in your computer:

Installing the maps in a GPS:

First of all, download file for GPS of the country you want from Downloads page and unzip it. You'll get a file called gmapsupp.img. The easiest way to have the map in your Garmin device is copying gmapsupp.img file within «Garmin» folder of the external SD/micro SD card of the device (create it if it doesn't exist). In some models gmapsupp.img file must be copied into «Map» folder instead of «Garmin» folder (note «Map» folder may be hidden). To copy it use a card reader (faster) or connect your device to the computer with a suitable cable, in 'Mass storage' mode (slower).

You can also use Garmin MapSource or BaseCamp software to send map to device. For that, you have to load the map in MapSource/BaseCamp first, as explained above.

Once copied, switch on the GPS, go to Settings>Map>Map Info and enable OpenStreetMap map. The way to activate the map varies from one model to other:

Topo maps on GPS:

You have two options in order to get topo maps on your GPS. Easiest one it to download both «OSM Base Map» and «Contour lines» for GPS of the country, that you'll find at Downloads page. You must install both files as explained in previous section.

Second option is to install Base Map and Contour Lines on your computer, select tiles for your area of interest of both layers and send them all together to the GPS. You can see here how to do it. This method may be useful for old models, which can only read one map file, or for very large areas not offered as a single file.

Using on Android devices:

If you want to see maps from this site on your Android mobile device, you can use OruxMaps App. You have two options for that:

  1. Use Android specific maps (recommeded):
  2. Use map for Garmin GPS:

I charged some maps on my GPS device Garmin Nuvi 25x5 but some big areas in some maps (for example Georgia and Uzbekistan) are white and with no data. Why?
Admin: This is most problaby an error during map generation. Please let me know what exact areas are missing, so that I can check and fix the issue.

Bonjour,
Je suis à l'étranger et je n'ai pas d'accès à un ordinateur. J'essaie de transférer la carte topo de la Guinée directement sur la carte sd de mon gps (montana 600) mais le gps ne reconnaît pas le fichier et la carte ne s'affiche pas. Existe t il une manipulation particulière ?
Merci
Cdlt
Admin: Vous devez décompresser le fichier téléchargé et copier le fichier gmapsupp.img dans le dossier Garmin de la carte SD.

How I loaded OpenStreetMaps using my MacBook Pro, then got them onto my Garmin eTrex 22x.

1. Downloaded the zip file for Basecamp, and unzip it, noting where the file is located on your computer. I downloaded OpenStreetMap USA.gmap.

2. Open MapManager, select "File/Install Map" and open the unzipped *.gmap file.

3. Open Basecamp and select "Maps/OSM-US. You will be abl to open the map in Basecamp.

4. Connect your eTrex with the SD card installed to the computer.

5. Open MapInstall.

6. Select device.

7. Choose Send Maps if all of the maps will fit on your SD card. If they won't all fit, choose Customize an select the maps you want to add by clicking Advanced / Partial Install. The storage meter (below the map selection screen) will display how much space the selected maps require.

8. Click Continue
9. Click Install (It may take a few hours)
10.Click Finish

After MapInstall is finished, eject the device. The maps will be available for use.
