Oh cool. I was hoping it would be something simple. I'll check this out the next time I'm in my car. I still have to figure out a good place to mount my GPS, as while geeks are impressed by a palm pilot GPS with CAT5 tied to it with cable ties, normal people find it kind of, well, geeky.

Once GPSApp gets dynamic routing, we're going to have to investigate some way of hooking up a compass and the spedometer so it can do dead reckoning like a real navigation system. Considering that NMEA is a boat thing where compases are important, and there are GPSes with compasses built in, are there ones that send the compas heading over NMEA?
