Problem Updating Nav III
Yesterday, I tried to update the software on my NAV III from 3.30 to 4.0. The install appeared to go okay, but once I restarted my unit, the unit tried to update the bluetooth firmware. This is where the trouble started. The bluetooth firmware update would only proceed to 45% where it would hang. The NAV III worked fine but there was no more bluetooth capability.
I ended up having to reinstall the 3.30 software for the NAV III...this allowed the bluetooth firmware to update to 100% and start to function again.
I read on other message boards that others were having identical problems.
