Garmin MapInstall Bug


Windows users, do NOT Update to Garmin BaseCamp version 4.7.0 and MapInstall version 4.2.0!

Mac Users are not effected.

Our maps utilize Garmin BaseCamp/MapInstall to load maps onto the GPS device. The current version of BaseCamp 4.7.0 released May 23, 2018 has a bug in the embedded MapInstall program version 4.2.0.

If you already installed version 4.7.0 or inadvertently updated to MapInstall 4.2.0, you must downgrade your MapInstall program to version 4.0.4 as follows:

Downgrade to BaseCamp v 4.6.2: In order to Downgrade first uninstall Garmin Basecamp, Garmin MapInstall and Garmin Express via Windows "Add or Remove Software". Then Install BaseCamp 4.6.2 - Download from here: http://www.gawisp.com/perry/mapsource/BaseCamp_462.exe

If after uninstalling your Garmin software, you still have MapInstall version 4.2.0 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.

How to determine your version of MapInstall:

In BaseCamp, launch MapInstall by clicking Maps -> Install Maps.

Position the mouse inside the MapInstall title bar and right-click. Select "About MapInstall".



Next, disable the MapInstall program from checking for updates in the future. Again, position your mouse in the MapInstall title bar and right-click. Select "Check for Software Updates". In the popup dialog, remove the check mark from the "Automatically Check for Updates". NOTE: this will not disable the auto update dialog for the BaseCamp program, just the embedded MapInstall program.
