Other Comments: Sometimes Maemo Mapper just stops updating the position. I suspect the Bluetooth connection gets wedged. Turning the GPS off and back on, then closing the cover on the Nokia 770 and opening it again causes Maemo Mapper to reconnect to the GPS, and it starts working again.

I also tried gpsdrive on my laptop. It switched the GPS into a different protocol and Maemo Mapper stopped working. I had some fun switching it back into NMEA mode (http://mg.pov.lt/blog/maemo-mapper.html).
