Nüvi 770 "Enabling Bluetooth" hang

 

Hi,

I have this Nuvi 770 that all of a sudden will hang when trying to enable the Bluetooth. It will stay for ever on that "Enabling Bluetooth" Screen. The only way out is to power off the unit.

Tried many suggestions from different forums but nothing good. Also it seems that many people are having this problem.

Present software version is...
V4.20 for the Nuvi 770.
V3.40 for the Bluetooth.

Anybody has a solution for this problem ?

Thanks.
