So sergio2,
So if I take the unlocked version I can just copy the img file to my micro sd card,
If I take the locked version I need to run the Process with gimgunlockMapSigPatch :

Garmin Image Unlock gimgunlock up to v.0.03+MapSigPatch

Right?

For micro sd: I just copy the img to the root of the micro sd? Where should I put the db file? Just make a folder in the root with the name SQL/ and place the file in there?

Thanks! (Been a way for a while, now finally bought 64s)
