Do NOT Update to Basecamp 4.7.0 – MapInstall 4.2.0 is broken!


MapInstall 4.2.0 is broken. You will get it by updating to Basecamp 4.7.0 - however also individual update can happen. MapInstall 4.3.2 (part of Basecamp 4.8.4) is fixed - but so far only available to Apple Mac OS x users - not for Windows. Note however - Basecamp 4.8.4 only runs stable in english - translated version are very buggy!

Garmin released a new version of Basecamp - 4.7.0 - in order to remove many features that were not in accordance with the GDPR regulation. Actually it's not that 4.6.2 is wrong here - it's that there were a few web services - that Garmin switched off - and those were interlinked into 4.6.2 - so that actually in 4.6.2 some functionality is not working anymore - I could on a quick check however not discover any actual difference otherwise in relation to the GDPR regulations - so 4.6.2 is no different in this regard to 4.7.0 - well and new privacy page/EULA of course).

The big problem is that Basecamp 4.7.0 also ships an updated version of Garmin MapInstall - and that version is broken in so far that it does not reliably/correctly send any maps in .img format anymore! This also applies to original older garmin maps.

On Windows instead of the actual map - only the overview map is sent - so you will have a nearly "empty" map.

On Mac OS x the problem with MapInstall 4.2.0 is that it will often crash while sending maps. This got fixed with MapInstall 4.3.2. Do not update to Basecamp 4.8.x if using Basecamp in any language but english however - as the translated versions have countless serious bugs.


Switch to the relevant tab for information on how to downgrade to Basecamp 4.6.2/4.6.3 on Windows respectively Mac OS x


Basecamp 4.6.2 - WindowsBasecamp - Apple Mac OS x


If you are a Windows user and upgraded to 4.7.0 you have 4 choices:


  • b) Only downgrade MapInstall to 4.0.4: In order to Downgrade first uninstall MapInstall via Windows system uninstall, then simply go to C:\Program Files (x86)\Garmin\MapInstall\ folder - then delete all the content of the folder but not of subfolders. Especially leave the "Maps" subfolder. Then Install MapInstall 4.0.4 - Download from here:


  • c) Downgrade to Basecamp v 4.6.2: it can be found here:
  • ATTENTION - you need to first uninstall Garmin Basecamp, Garmin MapInstall, Garmin Express, and any other Garmin Software via Windows "Add or Remove Software" except Garmin Mapsource (if you have Mapsource installed, do not delete it because you might lose data saved in Mapsource). As the user data of Garmin Basecamp, Garmin Express or Garmin Homeport is saved in a separate database - you will not lose it.Then Install Basecamp 4.6.2.
  • If you simply install 4.6.2 without uninstalling Garmin Basecamp and Garmin Express, Mapinstall will not be downgraded. Alternatively if you are afraid about losing data - you could first delete the content from C:\Program Files (x86)\Garmin\MapInstall\ folder (but not of subfolders) - then ONLY uninstall Garmin Basecamp via Windows system "Add or remove programs" - then Install Basecamp 4.6.2.


  • d) Use the plain old Garmin Mapsource for sending maps. Yes it still works if you know what to do - just note that it does not check any maps installed - so do not send maps twice. Also it cannot like MapInstall overcome the 4GB limit by splitting up maps that you are sending. Else of course it cannot correctly show the contourlines - but sending maps will work. Mapsource 6.16.3 can be downloaded here:



  • f) Use the create_gmapsupp_img_with_mkgmap.bat Script - this will only work for Maps <4GB however. And you can only install full maps. It is found in the map Installation folder. It requires Java JDK installation and java added to Windows path.
  • Alternatively you can use the create_gmapsupp_img.bat Script - however mind that address search is not possible then.



Actually right now only a part of the overview map is sent - it would be nice if Garmin could send the overview maps in general too - as right now they are only used on Desktop. Would actually speed up the GPS devices a bit - especially if you have no activated Basemap on your device.


Restore Tracks/Routes that you created in Basecamp 4.7.0

If you chose to downgrade Basecamp and already created tracks/routes with 4.7.0 you will need to restore them. While updating/downgrading does not delete any of your data - routes/tracks that you planned with Basecamp 4.7.0 will not appear in Basecamp 4.6.2 after downgrade - only routes/tracks that you had planned before the 4.7.0 update will show up.

To solve that go to:


(note AppData is a hidden folder - you may have to enable windows file explorer to show hidden files and folders)

Now you rename folder 4.6 to 4.6.backup and 4.7 to 4.7.backup

Copy folder 4.7.backup and Rename it to 4.6


In Case of Problems with Reinstalling Basecamp - downgrading MapInstall:

Deinstall All Garmin tools/programs via Windows "Change or Remove a Program". Then delete the Garmin Folder  in "C:\Program Files (x86)". Then Reinstall all Garmin tools/Programs and make sure to use old enough versions (as linked here).

IMHO you do not need to clean the registry of any Garmin entry, nor do you need to remove any Garmin folders that are somewhere else then Program Files folders (so far all Garmin tools are x86 and not 64 bit - it's possible this will change in future - so then also delete Garmin folder inside "C:\Program Files".


You can still downgrade to 4.6.3 for the missing functionality. However MapInstall 4.3.2 or later  is fixed (at least with the download directly from Garmin or from here - the Mac Appstore version sometimes does not update MapInstall) - so just make sure not to use Basecamp 4.7. and if you upgrade to Basecamp 4.8.4 or later.

You can Either Downgrade/Upgrade MapInstall only, Or Downgrade Mapinstall and Basecamp

While windows users have good alternatives to Garmin MapInstall - on OS x the only real alternative is to use mkgmap.jar to create gmapsupp.img files. That is not so easy to do and requires Java JDK properly configured. However MapInstall 4.3.2 is fixed - so either downgrade to Basecamp 4.6.3 or upgrade to Basecamp 4.8.4 or later.


  • b) Upgrade to Basecamp 4.8.4 or later:
  • Attention - best get it directly from Garmin or from here - and not via Appstore. I have heard from people that the version from the Appstore only updated Basecamp but the got stuck with MapInstall 4.2.0 instead of 4.3.2


  • c) Downgrade to Basecamp 4.6.3 - To do so first Uninstall Garmin Basecamp 4.7.0 Then make sure that also Garmin MapInstall installation folder is removed/empty - If not uninstall all other Garmin software too. Then install Basecamp 4.6.3.


  • d) You could try to simply Install Garmin MapInstall 4.1.1. - I'm not sure if this works by just executing the installer. I think not. That means you first have to uninstall Mapinstall 4.2.0 - then Install only MapInstall 4.1.1 / MapManager 4.1.1. That way you could keep Basecamp 4.7.0 but I don't know why you would like to do so as Basecamp 4.7.0 is only a regression.


Basecamp for OS x can be downloaded here: (here you find all Garmin Tools for  Mac OS x for download - if you miss something else)


MapInstall and MapManager for Mac can be downloaded here:

    Herzlichen Dank, hat geklappt mit 4.62; ich benötige diese Version nur, dass ich auch direkt mit Google Earth arbeiten kann, um fehlende Wege zu finden und nachzuführen.
    Herzlichen Dank für den raschen feedback….

    Am 30.10.2019 wurde von Garmin für Windows Basecamp 4.7.1 veröffentlicht:

    Weiß jemand, ob bei dieser Version MapInstall funktioniert?

  • petter

    Hi, I am now trying to install the maps for Japan. This set is smaller than China and does fit on my Garmin 64S. Everything goes as normal, until I get the standard message that “this insatllation could take more than one hour” Are you sure? Then there is a “confirm” to click, doing this I get the meaningless message:
    There was a problem while installing maps on your device. Ensure that the device is plugged in and turned on, and try again.

    Unclear what to do, the device is sitting on USB in Garmin “receive” mode, just as it has when doing this successfully many times before. At least this shows that there is nothing particular with the china map. What to do? Anybody recognize this problem? Thanks a lot! Petter (from Norway)

      Never heard of that problem – but it sounds to me like the broken version of MapInstall – it throws random errors. You need to upgrade or downgrade MapInstall. 4.1.1 won’t work. Else you can use the gmapsupp.img downloads instead and just manually copy the gmapsupp.img over

  • petter

    Thanks again, I guess this is stupid, but I cannot even find your top folder programfiles located under ?? Macintosh HD or ?? There seems to be Garmin in many places, I never moved anything however.. I will try deleting stuff then download Basecamp again once I know all the stuff that should be deleted..

    • extremecarver

      Oh – you under OSx not windows. Sorry. I’m not sorry where MapInstall is installed on OSx – do not delete any folder that is not called Mapinstall. maybe on OSx also just overinstalling of the MapInstall 4.1.1.dmg is enough but AFAIK you should find MapInstall in the list of installed apps to deinstall.

  • petter

    Thanks for your reply extremecarver!, I will delete the folder (do you have the path?) then try again. Concerning unicode (your second reply) what exactly do I need to do in order to get my map of China (i will need to reduce it to the EAST part) to load correctly on my Garmin 64S ?? I have loaded other maps previously, always succeeded in the end, but this time things crash more consistently. I appreciate any help, since I plan to go to China soon, this is sort of urgent.. Thanks again, Petter

  • petter

    Hi again, for completeness my Garmin unit is 64S. I just did a complete reinsatllation, but nothing changed. Related to this is there a way to only get a part of China aside from the Mapinstall select/deselect tiles? China is very big and I only need a small piece of it. I have now tried repeatedly to get china onto my GPS, but no luck..

  • petter

    Hi, I am having problems with mapinstall, this is an updated version. From Basecamp the program just says installation complete WITHOUT installing, from Mapinstall itself, I go through a partial select (China is too big), the program fails when the insatllation should have started, just saying try again, make sure your device is plugged in etc.. Any hints or ideas? This has worked previously, always with various error messages, but in the end worked.. best regards Petter (norwegian living in Hong Kong)

    • extremecarver

      you need to delete the MapInstall installation folder – then reinstall. MapInstall 4.1.x will NOT send the map correctly. Alternatively use the gmapsupp.img download of China (and depending on your device you may need to use the non unicode english version)

    Herzlichen Dank, Felix, für die rasche Antwort. Dank deinem Tipp konnte ich Basecamp 4.6.2. wieder installieren und die gewünschte Karte aufs GPS herunterladen.
    Mit freundlichen Grüssen

    Hi Felix,

    can’t downgrade to Mapinstall V 4.0.4. Whenever I have used a link to version 4.0.4 I ended up with version 4.2.0

    Any ideas to solve the problem?
