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 programs QLandkarte GT or QMapShack. With the topographic maps you can also calculate profiles for your routes.

Viewing the maps in your computer:

  • Linux: you can use Qlandkarte GT or MapEdit++ (the latter is for Windows, but works fine under wine). For both of them, first step will be to unzip downloaded file in the folder where you want to keep the maps. Files named «OpenStreetMap_*.exe» can be uncompressed with p7zip (7z e OpenStreetMap_*.exe). To use the map in QLandkarte GT use File->Load Map menu. Then give the path to file AAA-XXX.tdb in the folder you uncompressed the map and then to file AAA-XXX.img. AAA is the ISO code of the country and XXX a three digit code different for each map.

    You can also use MapSource with wine and load maps running the auto-install file (wine OpenStreetMap_*.exe) or installing maps with MapSetToolKit (wine MapSetToolKit.exe) as described below:

    • Unzip downloaded file in a directory of your choice.
    • Run MapSetToolKit and click “Install” button placed at the bottom right corner. A dialogue will appear with some blank fields:
      • Registry name: introduce any name for your reference.
      • TDB file: browse to the file AAA-XXX.tdb you have downloaded.
      • Overview map: browse to the file AAA-XXX.img.
      • Maps directory: it is filled automatically after giving the path to the files above.
      • TYP files: same than with previous files, but searching for AAA-XXX.TYP file.

      Installing a map with MapSetToolKit

      • Click “Install”, close the application and you are done. You now have the map available on MapSource and BaseCamp.

  • Windows: maps can be used with the open source programs Qlandkarte GT or MapEdit++ or with Garmin software MapSource/BaseCamp. For the first two, you must start uncompressing the downloaded file in the folder where you want to keep the maps. Files named «OpenStreetMap_*.exe» are uncompressed with 7zip. To use the map in QLandkarte GT use File->Load Map menu. Then give the path to the file AAA-XXX.tdb in the folder you uncompressed the map and then to the file AAA-XXX.img. AAA is the ISO code of the country and XXX a three digit code different for each map.

    In order to load maps in MapSource or BaseCamp, you just have to run the file named «OpenStreetMap_*.exe» or «Curvas_nivel_*.exe» and follow wizard steps.

  • Mac: you will need the programs Stuffit Expander, Garmin BaseCamp and Garmin MapManager installed in your system. To see the maps on BaseCamp you must proceed as follows:

    • Unzip downloaded file in a directory of your choice with Stuffit Expander.
    • Start Garmin MapManager. You will be prompted to select a file to open. Select the map file previously uncompressed and click 'Open'.
    • Click 'Install' and quit MapManager when it has finished. The map is now ready to be used on BaseCamp.

    Installing a map with MapManager

Installing the maps in a GPS:

  • The easiest way to have the map in your Garmin device is copying the file gmapsupp.img in the external SD/micro SD card of the device, within a folder called Garmin (create it if it doesn't exist); in some models gmapsupp.img file must be copied into Map folder instead of Garmin folder. This method is also recommeded because in case of any problem with the map, removing the card and restarting device will be enough to solve it. To copy it use a card reader or connect your device to the computer with a suitable cable, in 'Mass storage' mode.

    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:

nüvi 300:

Entering map setup on nüvi
Under Map Setup, enter Map Info

Legend HCx:

Enabling map on nüvi
Tick OpenStreetMap map to activate it

Entering map setup on Legend HCx
Enter Map Setup

Enabling map on Legend HCx
You have to activate each of the tiles

  • If you don't have an external card, you can use any of the free programs sendMap or Qlandkarte; you can also use MapSource or BaseCamp from Garmin. In the last cases, you first have to load the map in MapSource/BaseCamp as explained above.

High resolution contour lines (Spain and New Zealand):

  • These contourlines have been generated from data published by the National Geographic Intitute of Spain and Land Information New Zealand.

  • To install them in the computer you just have to run the auto-installable file provided with the download. Linux (without wine) or Mac OS X users will need to uncompress the file with 7zip, prior to install it (in QLandkarte GT for example).

  • Comparison between IGN and SRTM contour lines, for the same area (Almanzor peak in Sierra de Gredos):

SRTM contour lines

Hi Carlos, I'm still having trouble with the whole Europe download. Still getting the compressed map files but no installer file. I've tried the truck version - installer is there, but when installed, there is still missing data in some of the maps (e.g. NW France and parts of Scotland and Spain). Can you please have a look?
I'm really sorry for the inconveniente. I'm having problems to build Europe map, due to its huge size. I'm waiting for a new computer that will be able to manage it, but don't know whet it will be available. In the meanwhile I continue trying to build Europe map, I'll let you know if succeeded.

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?
Please have a look at the FAQ. That page is still under construction, but that issue is alredy described.

Hello. Is possibel to add maps in to garmin quest 2 ?
Is a great gps but with no updates!!
Tanks a lot!
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)

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