Thread: Garmin GMA protection and the "Unauthenticated" status

1. Install [Only registered and activated users can see links. ]. This is a legal method of getting Mapsource on to the computer without buying a map set.
2. Install [URL="http://www8.garmin.com/support/download_details.jsp?id=209"]MapSource[/URL

I believe if you unpack the Mapsource first, then run the .msi file instead of setup.exe, you do not need to install the Training Center.
