Question about Garmin nuvi 780 GPS
Worked for me but not sure why, I had the same problem of freezing when updating Bluetooth firmware on a Nuvi 770. I chose to reset all user data (press lower tight hand of touch screen while powering on) and next reboot it updated firmware sucesfully. No idea why this worked.
