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

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 (800x600 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:

Additional Explanation for Maps with separate Downloads (contourlines - or mapfiles for huge maps like Europe continent map)

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.

The installer will ask you to provide them! (it's easiest if you simply download all files into the same folder!).


Make sure all parts are actually fully downloaded (in the screenshot below - the needed europe_contours is still downloading - that's why you see the europe_contours.7z.part.


For maps with separate contourlines - make sure to tick the option to install them. It is not activated by default (on first installation).


The installer will ask you to open the separately downloaded file(s). You can see the message "Please open mtbeurope.7z" - so we click on mtbeurope.7z - then click on open at the bottom.


Then just wait until the installer reaches 100%. Attention for maps with 2 separately downloaded additional files (currently Europe and Asia). You will need to select the second file after the first one is installed. Separate contourlines only need to be unpacked once however. On map updates you do not need to download them again, nor do you need to provide them to the installer again. The contourlines integration option will automatically be activated if contourlines were integrated before the update!



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:

Select layout



Possible Problems under Vista or 7 or 8:

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 very old GPS devices (pre 2009 or older). You will need to install Java JDK on your computer for this however.


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.

    Hello –
    I am using openMTB and Velo US-West maps on a Garmin 1030. If I wish to just update the maps, is it necessary to download and install through the Windows installation process every time? I only need to create the gmapsupp image file for each and move them directly to my Garmin. I do not want to set them up for Basecamp every time. Or more simply stated, I just want to download the latest version of the maps, then put them directly on the Garmin 1030 device. When reading your tutorials, it does not make this clear. Thank you.

      The easiest then would be download the gmapsupp.img versions instead (and keep the contourlines in a separate .img file – so you have less data to download/transfer). If you get the windows installer – you have to update them on PC too. Note that if you plan routes on PC with basecamp to send them to the 1030 – they really need to be planned with exactly the same map as on the device. If you use tracks – you can also use an older / newer / different map for planning.

    Guten Tag,
    versuche die Europa Karte neu zu installieren. Es gelingt mir nicht, da die Installation der Karte abgebrochen wird mit der Fehlermeldung (siehe Screenshot7); habe die Riesendatei mehrere male immer der gleichen Fehlermeldung auf 2 versch. PC…
    Was ist nicht i.O
    Danke führ ihre Hilfe

      Hallo Othmar, es gibt vier verschiede mtbeurope.7z – du musst die Non Unicode English Language herunterladen(diese passt zum Installer). Du hast wohl eine andere Version der mtbeurope.7z herunterladen als vom Installer.



    Thanks for great work. I always update the maps on my Garmin 1030, but I noticed that some of the old versions are not getting overwritten or deleted when installing the latest versions. So I end up having multiple versions of the same maps. Can I simply solve this by deleting the old img files on the SD?
