"Unauthenticated" message comes in gps if you dont have .gma file.
If your map in MS hasnt been unlocked by JM, it's not patched correctly.

When patched MS and unlocked the map ,send it to your hd (C:/Garmin/gmapsupp.img) and run Fast Img Unlocker on it to avoid the "Unauthenticated map" message.
this is already explained in post 41 as said above.
Try to read threads it helps![]()
