Install Garmin Basecamp (and maybe Mapsource)

Install Garmin Basecamp:

Just follow the guides Garmin has on their own homepage. Garmin Basecamp is the best program to use the OpenMTBMaps and Velomaps. Attention - version 4.7.0 is heavily bugged - please use 4.6.2 until a fixed version 4.7.1 or higher.

Best download the current Garmin Basecamp version from Garmin - I have attached here some older working versions should Garmin introduce some bugs to newer versions again. 


You can download Garmin Basecamp from here: Garmin: BaseCamp Updates & Downloads



Why to not use Garmin Mapsource anymore!

Attention - I do not recommend to use Mapsource anymore except for sending maps to older generation devices!

Some reasons:

a) It's not developed anymore since 2010

b) It does not show OpenMTBMap or VeloMap contourlines! (it will send them though to your device)

c) It has no proper database to store tracks or routes - yes undertanding the concept of the database in Basecamp is not easy - but once you got it, it is pretty well done!


So why would you still use Mapsource?

Well to send maps to older generation devices like Vista HCx or GPSMaps 60CSx or even older. Basically to all devices that only support a single gmapsupp.img file! The advantage is that with Mapsource you can select the region on fullscreen - instead of the small popup screen of Basecamp/MapInstaller.  Also it will display you a list of all selected tiles - this can be useful for debugging (though normal users don't need this).

Another reason would be that Garmin Mapsource has a search function that is identical to your GPS Device. The search function is actually much better than the Basecamp search function - but for general use I don't think that makes it worth-wile to stick to Mapsource.


So just install Garmin Basecamp instead: 



For Reference only - Install Mapsource without owning an old Garmin Device

There are several programs to display openmtbmaps on your PC/notebook. The most popular is still Garmin Mapsource - even though it is superseeded by Garmin Basecamp and also Qlandkarte GT is on the way to overtake it. Garmin Mapsource is not develloped anymore, but version 6.16.3 runs still pretty well and has no big bugs. There is a catch however. Garmin only provides updates, no actual installation packages. Therfore below I describe two ways how you can install Mapsource legally nevertheless.

People who have bought a Garmin GPS will have a CD shipped with it including Mapsource.  I recommend to use the most uptodate version by Garmin (as of writing this is 6.16.3)

Earlier versions of Mapsource (also 6.13.6) are now incompatible with the openmtbmaps as they do not show all ways and streets!!!! Use at least 6.16.1 or higher. Note that while Basecamp shows contourlines, Garmin Mapsource doesn't. Hence for general use I recommend Garmin Basecamp instead.


Classic Way of Installation without already having Mapsource installed (please install everything as administrator)

  • 1. Install Garmin Basecamp.   This is also a great tool for viewing maps, or planning routes and tracks.
  • 2. Download and Install at least two Openmtbmaps (from )
  • 3. Download and install MapSource 6.16.3 from here:
  • Note Mapsource will only install if you have done 1. and 2. before. It is essential that you first install two maps AND Garmin Basecamp - else you have to do the advanced way of installation below

I recommend installing a second map (good idea is to install the map legend so you can get to know the layout!!!) because you need to have two maps installed before the map selector shows up. Essentially 1 map would be enough also.


Advanced Way of Installation without already having Mapsource installed

  1. First install at least one openmtbmap (just run the .exe)
  2. Attention, Mapsource will not install correctly until you have a at least one map installed. So if you forgot step 1, do it now! Go to and download the map(s) of your choice and install at least one map!
  3. Download  latest MapSource from Garmin ( ).
  4. Unpack or extract the content of setup_MapSource.exe using 7zip (, WinRAR or another good unpacker.
  5. From the extracted files, first run MAIN.msi.
  6. Then, run Setup.exe.  Note: The sequence to execute Main.msi and then Setup.exe is important to avoid “Previous MapSource not found!” error.
  7. Garmin MapSource is now installed. I recommend installing a second map (good idea is to install the map legend so you can get to know the layout!!!) because you need to have two maps installed before the map selector shows up.

Note I still recommend to install Garmin Basecamp nevertheless: Get it here:


Attention Mapsource 6.13 6.14 and 6.15 Users:

Please update to at least 6.16.1 -- earlier Mapsource versions miss a lot of ways and streets and make the maps unusable.


Parallel installation of several Mapsource versions:

Simply unpack a mapsource update (see links above), run MAIN.msi and then rename mapsource.exe to something else. e.g. mapsource_6.13.6.exe and then copy it into your main Garmin Mapsource installation folder (usually c:/garmin). Now you can decide which of the two versions you want to use.

    weiß Jemand wo man BaseCamp 4.62 für OS X noch herunterladen kann?

    Danke schon im Voraus.

    I have installed openmtbmaps and downloaded the Europe Premium Map in the Garmin folder in C drive.
    Now I installed the Garmin Basecamp. How do link the data in C:Garmin to Basecamp to transfer to SD card to use in Montana 650.

    I would like to know if it possible to install OpenMTB maps for separate parts of the world and be able to work with them separately in Basecamp. I currently use the mapset for Australia but would also like to access the mapset for Great Britain from the same instance of Basecamp.

    I currently use create_gmapsupp_img_with_mkgmap.bat to build the Australian gmapsupp.img for my Garmin Montana 650t with no problems, but would also like to do this for other countries independently.

    If I downloaded and installed mtbgreat-britain.exe, would this create an installation folder separate to Garmin/openmtbmap/Australia ?

    Thanks for your help.

      if you install another map – it will by default be installed in another directory. If you use the create_gmapsupp script – just rename the gmapsupp and put it also on your mSD card – no worries. Just make sure not to install too many maps – I would stick with max 6-10GB at a time (it’s enough to rename to e.g. gmapsupp.img.bak to completely deactivate a map on mSD – deactivating in map menu is not enough). In Basecamp if you have several maps installed you can select the maps with the map selector toolbar.



    wie führe ich eine Asienkarte und die separat geladenen Höhenkonturlinien nach dem Download zusammen?

    I am facing the with overlapping map in border region. So currently I choose the specific tiles via mapinstall fitting to my hometrails reachable for a day trip.
    Overall the Europe map looks to big to me.
    What I would prefer is only to download the maps I really need and merge the ones causing issues with overlapping. So i.e. “NRW”, “Rheinland-Pfalz”, Netherlands and Belgium.
    Other option I was thinking about is to have presets for the tiles choosen. But would be my second option as it would still need to download full Europe.
    Or any other proposal?

    thx in advance



    • extremecarver

      Well no – right now you’re only option is to download the full map of Europe – and then select your selection using mapinstall. (except for trips in the Alps – as that is right now the only non continent map spanning several countries).

      Offering presets from the europe map for Europe won’t work – as the oveview map and some other files would conflict.

      I hope in Spring this will change – either I will offer a new mechanism – or split Europe into 3-4 overlapping parts.
