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

First download USB Garmin drivers,connect nuvi USB ,set Windows to see hidden files and folders, go to .System folder in nuvi and backup on pc your preloaded files: gmapprom.img gmapprom.unl and gmapprom.gma.
Then delete the old map on Nuvi along old .unl and .gma.
Unlock the new map, rename it to gmapprom.img and put it in the same place where you found the old one. Safely disconnect Nuvi from pc.
