catymag u urself replied .. i am blessed!! I'm using the Nuvi 50 LM .. i downloaded the zip file.. extracted to a directory and unlocked using FIU. Then when i tired to copy the img file to the device it gave an error that the device didnt have enough memory. I deleted the text and keyboard files that i did not need. Then copied the img file to the device. turned it on and only USA maps where in the info section in settings --> maps--> info.
Then i renamed the img file from gmapsupp.img to gmapprom.img. Still didnt work and still wasnt showing in the info section in settings--> map.. please help me out as i cant understand what im doing wrong.

Thank you very much
