Garmin mapsource “Previous MapSource not found!” error
Tuesday, August 4th, 2009I just wanted to do a fgresh install of Garmin program MapSource and I downloaded the installation files from garmin webpage.
When I try to install “Setup.exe” Iget an error “Previous MapSource not found!“.
So I checked the net for answers and solution to the problem and I found one that works.
MapSource Installation instructions:
1. Download MapSource software updater from Garmin.
2. Extract file MapSource_6156.exe downloaded using 7-zip or WinRAR.
3. From the extracted files, run MSMAIN.msi.
4. After that you can run Setup.exe and installation will be successfull.
Have a nice day and start using the MapSource for Garmin navigation…
