I have a US garmin nuvi 255W. do I just switch the image here with the one currently on the garmin? when do I use the unlock code? thanks for any help
I have an 855 Nuvi. The English download unlocked with Fast IMG Unlocker and then renamed gmapsupp works fine. I also tried it on my GPSmap 60Cx and it also works fine. I DIDN'T try JCV.

Yes. Just copy it to the appropriate folder on your device, and it will overwrite the previous version.
You may wish to back up the old map first. And you need to ensure the new map has the same name as the old map eg gmapprom1.
You run the unlock prior to installing the map (img) onto you 255w.
Thanks. Can this be used with MapSource on the desktop?
Can anyone get this to work on 3790T US firmware? I can install it on my 270 US no problem, but not to the 3790. It says unable to unlock maps.
EDIT: I got it to recognize the map by renaming it gmapsupp1 - very strange.

Thanks. TSM 11.1 works fine for my 215W. Try to activate JCV now.
