Garmin GMA protection and "Unauthenticated" status
Quote:
My solution is below, and eliminates the need to use the Jetmouse Keygen, does not require patched Mapsource executables, and strips out GMA authentication. This tutorial assumes use of an unpatched Mapinstall, which limits transfers to the GPS or SD cards. There is a patch for MapInstall (see notes below) that removes this limitation.
- Install [Only registered and activated users can see links. Click Here To Register...]. This is a legal method of getting Mapsource on to the computer without buying a map set.
- 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.
GMA issue on the Montana 600
As you all have confirmed, it seems older and unlocked maps are loading onto these new Garmins (just got a Montana) but Maps with ids newer than 2200 get the Authenticate error. I tried using the app mentioned in this thread, "Unlock_Mapset.exe", and though you need to run it for each Mapsource product, it does appear to work! I ran a test with the City Navigator 2012.20 (For which I have a lifetime subscription) loading just two map segments, and they worked! Trying a larger set now. In addition, the new Garmin Bluechart G2 Vision chart works.
