How to install the Openmtbmaps

To install openmtbmap maps on Windows just run the .exe download

Note Linux/Mac OSx users can simply unzip the installer with 7-zip or unarchiver.

There is a tutorial here for Mac OSx users: Convert-maps-for-mac-os-x-roadtrip/

And here for Linux (Qlandkarte GT) users: todo


The first screen will popup several seconds after you double-click on the downloaded map. As there is an integrity check (checking that the download was fine) it may take some time (the bigger the map the longer) until this pops up.

Click on next to proceed.



On the second screen please reed through the license agreement // Copyrights and if you accept the terms of it, click the checkbox and then proceed.



This screen will be shown for all maps for which contourlines are integrated into the map. If you activate the second checkbox ("integrate Contourlines for Country") then the map will be installed with contourlines. Notice: the contourlines are only shown in Garmin Basecamp or Qlandkarte GT (as well as on all Garmin GPS devices) – but not correctly in Garmin Mapsource. If you don't activate it – then the map will not include contourlines. This could be benefitial in very flat countries like the Netherlands, or if you feel the contourlines disturb you when using the map.

The third checkbox will install a (virtual) separate map with contourlines only. You can use this to send a separate contourlines map to your GPS device.

select contourlines options


On the forth Screen you have to choose the layout. There are 5 different layouts available for GPS use and one for Desktop use. Often new users of the Openmtbmap will ask which one they should choose. As there is not that much space to give detailed explications in the installer, I will explain it a bit more detailed:

  • Let's start with the last one in the list that is selected by default: Layout for Mapsource, Qlandkarte GT or PC/desktop screens. This is a low contrast layout suitable for desktop/PC use (800×600 pixels and up). It does not provide enough contrast and clarity on your GPS device however. If you choose it you should change it before sending the maps to the GPS device. This can be easily done by running "change_layout_for_openmtbmap_country.exe" (after installation there will be a link to it in your start menu).

Besides the layout for desktop/PC there are 4 different layouts available. Choose them according to the GPS device you have.

  • Classic layout – this is optimized for etrex devices or edge 705. It is optimized for non touchscreen Garmin GPS.
  • Thin layout - thinner tracks and pathes compared to classic layout – it is optimized for Gpsmap60/76 and Dakota series which have low resolution for their screen size.
  • Wide layout –  very high contrast layout, like classic but with nearly white forest so you can see ways and other important information even while riding your mtbike. It is optimized for Garmin Touchscreen GPS with high resolution like Oregon, Colorado or Montana. If you have bad eyes and you are mainly interested in seeing ways and pathes at quick glance then choose this.
  • Hiking layout – Choose this if your main interest with the maps is hiking. Specifif Bicycle/MTB information will not be shown.
  • Easy layout – it is similar to classic layout – but focussed on easy readability hence not showing mtb/bicycle information except cycle routes. If you feel that the other layouts are overloaded or difficult to understand, then choose this layout.


You can change the layout at any time (e.g. before sending the maps to the GPS device). This can be easily done by running "change_layout_for_openmtbmap_country.exe" (after installation there will be a link to it in your start menu).

Choose map Layout


On the fifth screen you can choose a folder into which you can install the maps. Please note – do not change the folder afterwards by hand. If you want to change it, then best first uninstall the map, and then reinstall to another folder (simple reinstallation is also okay, but you will need to clean up the old folder by hand).

Choose installation folder


That's it, simply click on install and once it's finished you can see the map in Garmin Basecamp or Garmin Mapsource.

There will also be a link to quickly create a gmapsupp.img file for your GPS in your start menu (as well as a link to change the layout and uninstall the maps again).




Select Map in Mapsource/Basecamp:

Once installed – you have to select which map is shown in Mapsource/Basecamp. There is a drop-down menu in the top left as soon as you have installed 2 different maps. The menu is placed to the left of the "+" and "-" buttons which are used to zoom in/out. It is only shown if more than one map is installed.

This is how it looks in Mapsource 6.16.3

Select map

and this is how it looks in Basecamp 3.3.1:

Select map


Add Contourlines – For maps with contourlines as a separate download.

Some maps, especially the continent maps, or all other maps where the contourlines are very big in comparison to the size of the map, have the contourlines integrated, but you need to download them separately. Extract the contourlines directly into the map installation folder.

Then – as in the screenshot below – you need to have 6*.img – 7*.img (these are the contourlines you should have unpacked right before) and mapset* files. All in one directory/folder without subfolders:


Update the openmtbmap maps on Windows:

Simply Run a newly downloaded .exe, it will overwrite the old maps and select by default the old installation folder. If you want to install the maps to another folder, you can do so. (afterwards, you can then safely remove the old folder).


Change the Typfile / Layout of the openmtbmaps:

Simply run change_layout_openmtbmap_country.exe. This will be found in the installation folder after the maps are installed. There is also a link to it from the Start Menu.

Simply click on next.

Select map


Choose the layout you want to see now and click on install – for a more detailled overview of the different layouts read through the installation instructions on the top of this page:

Possible Problems under Vista or 7:

I have heard that Windows Defender may cause Problems, the same might be true for UAC. So in case the installation does not run clean, deactive both temporarily.

Problems: Mapsource doesn't start after installing the maps. This usually only happens if you move the folder into which you installed the maps. You can check with Mapset Toolkit from here: and analyse what went wrong and/or delete any entry related to Mapsource from the registry.


All my other maps dissapeared on my GPS:

Notice that when you send maps to your device they are usually put into gmapsupp.img. So if you don't want to loose your old maps make a backup of gmapsupp.img and the use gmaptool to add the maps to your old gmapsupp.img. Or just as usual send all maps together from Mapsource to your unit.  This is also true for using Sendmap.


Installation directly to PNA without Garmin Mapsource:

Simply run create_gmapsupp(_with_mkgmap).img.bat then copy the gmapsupp.img to your GPS into the /garmin folder (gmapsupp.img MUST NOT BE RENAMED on many GPS – even though on newer GPS like Dakota/Oregon you can have several *.img in /garmin folder which will be read, there are often problems associated to this so I recommend not doing this). You can also use sendmap for this (compatible to Windows, Linux, Mac). Get it from here: Or use mkgmap instead. Both programs run on most platforms.


Changing / Moving the folder in which you have installed the maps

Attention, never change the folder from which you run the install*.bat. If you do this, then Mapsource will not start. Also if you delete the folder or the maps inside.

If you face this situation, or want to change the folder uninstall the maps, and then reinstall the maps.
