I dont want to make any change before i backup the NV.
What else do yo suggest me to do?
You mustnt find any archive, but just your region 41_backup-bin-
NV backup is not the backup of files of Nuvi, but the NonVol memory backup,it contains Nuvi ID, all the maps codes, probably your Nuvi registration date on myGarmin and first satellite fix etc. Everything is in reg 41,all in these few bytes.
Anyway, better you dont do anything weird till you havent understood what are you doing.
Better you keep your 3790 and you read something else and learn at least the abc of these stuffs or you risk to brick your Nuvi

EDIT: added a note about what NV backup means in post 337
