I hear what you are saying, but are you sure the GPS receiver outputs 
the compass heading as part of the NMEA data? No matter what, the GPS 
receiver must be reasonably level for the flux gate compass to work. The 
factory setting for the speed threshold is 10 mph to toggle from flux 
gate to GPS bearing, but it can be configured anywhere between zero and 
99 mph or kph. However, as far as I know, the flux gate compass is only 
for use on the LCD display... i.e. it doesn't output the flux gate 
compass bearing, but someone can correct me if I'm wrong.

Hopefully you can come up with another way to beacon the camera azimuth.
