Thanks for all the help. A couple of things:

1. I changed the 770 f/w to 5.2006.13-7. This appears to make maemo-mapper work for longer but, it still fails.

2. It looks like I have 2 options (can you confirm?)

a. Update to 2006 FW and see if this fixes it. I've heard mixed comments about the 2006 SW. Has anyone with dropping out problems moved to 2006 and has it cleared their problems?

b. Try the bluetooth reset script. Is this still a valid option or does the latest maemo-mapper code try this?

Thanks.
