My 3750 is damaged (for NVM config.) then it turn to 37xx and 34xx as picture.
Flashing by original firmware won't fix this issue.
Your 3790 is ok to show 3790., don't try to change to 37xx or 34xx.
OK, thanks. BTW modifying NVram it's possible to flash Nuvi 3790 to SG/MAL or CHN latest firmware. Pity, but I don't know which way modify NVRam. On garniak.pl forum is hint from PouchX. But it's too complicated for me.
