Thread: Nuvi 255W

I have downloaded the Garmin city Navigator North America NT 2015.30 Unlocked IMG

Old map, released one year ago, we are at 2016.20 now.

I have followed the instructions down to the letter.

Good instructions? We don't know

I also tried adding a unl file.

If it's unlocked it wont work.

I also tried the Garmin Unlocker

Too old to unlock new maps.

"No detailed maps found that support routing. The Nuvi cannot be used without them."

Nuvi doesn't see your map
Wrong naming?
Not unlocked properly?
Wrong path?
Old .unl file left in nuvi?
Look at Tutorials Index to get info and instructions or give more details.
