Maps for Garmin based on OpenStreetMap

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:

good morning
your advise is to install the additional map (gmapsupp.img) onto the sd card under the folder Garmin or Map. If I want to install several additional country maps (eg. switzerland, germany, france)on the sd card, they would all have the same name like gmapsupp.img, which doesn't work. Can they be renamed?
Admin: Please have a look at the FAQ. That page is still under construction, but that issue is alredy described.

Tanks a lot!
Admin: My maps should work in all Garmin models, but I don't have experience with the Quest 2 though. You can give it a try. Look at "Using the maps" section for information on how to install the maps

Hello, I like to share information for Garmin nuvi 30, 40, 50. The folder you need to put the map file is not in "Garmin" folder, but "Map" folder, then you can use the map from Settings>Map>Info (mine is Nuvi 40, I don't know about other), check the "OpenStreetMap"(OSM) file you want to use, uncheck "CN" Map file, it seem CN Map have higher priority than OSM(atleast in my Garmin Nuvi 40LM)

Admin: Thank you very much for the info, I'll update "Using the maps" page with it

Hi, ive downloaded the spanish maps onto my garmin nuvi 205w. All maps installed and selected all ok. Calaculated a route to address in spain and the route travels over land, rivers (in the spanish section) and does not stick to roads. Any ideas? Many Thansk
Admin: It should lock on roads. Are you in the UK while calculating the route? Maybe you need to set your position in a place near the start of the Spanish section of the route.
