Also check they're capable of voice calls - not all of them are. Aren't they 
going to be too big and power hungry though? It wasn't clear to me whether the 
minibook had mic and earpiece suitable for phone use either. 3G modules would 
be smaller - check out telit and the one identified for gta04. I don't know 
how they connect though.

The ones I've seen are probably too big. you could just connect a gps chip to 
the serial port, and get AI to help with getting the impedance right for the 
antenna trace. Sparkfun have a selection of gps chips and antennae, including 
a tiny chip antenna that might be good enough. Remember to stick the antenna 
somewhere it can see the sky!

Nothing for gyro or compass? The circuit from the nav board v2 should connect 
directly to the 40 pin connector to provide these.
