Thread: Nuvi 3790 lost bluetooth and voice command

no luck, still not working. I try the 390 firmware download from garmin but still not working.

with hex editor I search bluetooth and I fount it in the firmware 410, also the voice command. I don't know why it don't show on the menu.

I think I could try to convert it to sg/man firmware but can I go backup to Europe version? original? because I want to use Ecoroute HD.

what you think?
