Old map, released one year ago, we are at 2016.20 now.I have downloaded the Garmin city Navigator North America NT 2015.30 Unlocked IMG
Good instructions? We don't knowI have followed the instructions down to the letter.
If it's unlocked it wont work.I also tried adding a unl file.
Too old to unlock new maps.I also tried the Garmin Unlocker
Nuvi doesn't see your map"No detailed maps found that support routing. The Nuvi cannot be used without them."
Not unlocked properly?
Old .unl file left in nuvi?
