if you want to update a previous CNNAM , before doing anything ,backup your gmapprom on your pc, then rename the new gmapsupp.img unlocked exactly like the old one and copy it in the same position the old one had in your nuvi.
If you have the last firmware perhaps the map will be locked so you must add an gmapprom.unl created with notepad
instructions:
to unlock an unlocked IMG
rename the map gmapprom.img and unlock with jetmouse keygen creating the unl file with notepad

on jetmouse keygen v1.5 put either the 10 digit gps unit id number (will be unlocked only in your gps)or the sd serial # (it will be unlocked in any gps you put the sd card
under-select map product --on the bottom ---custom map set---add the maps FID# also called mapid #

click generate a few times on the bottom-all those numbers will unlock the map--copy that 25 digit number into the gmapsupp.unl file --- don't add a enter --just 25 digits on the first line ----
on a sd card create a garmin directory--in that directory copy your gmapprom.unl file (unlock file) and the gmapprom.img
When you save the .UNL file in Notepad, be sure you set the "Save as type" to "All Files", not "Text Documents".
copy the unl file in the map folder
