The problem is related to the Garmin new GMA protection.

- "Garmin GMA protection and the "Unauthenticated" status
Upgrading MapSource to a the latest Garmin original version will NOT remove any of your unlock keys. The problem is that all maps having a MapID >= 2200 will get the "Unauthenticated" status. That status means that they are unlocked correctly but lacks the new GMA digital certificate to authenticate your installation as a genuine licensed map installation.
The solution is to use the patched versions of MapSource, MapInstall and also BaseCamp."
