Does anyone know if the garmin gps 76 (for example) that contains a compass ,
send the compass heading in a NMEA sentance?  I know the compass will be
displayed on screen if you are moving at less than XX miles per hour, but is
that also used in the $GPRMC?  or is there a special sentance for compass

The reason I ask is that this just came up on the tinytrak sig on yahoo...
someone wants to send packet audio with ATV (fastscan) pictures and it sure
would be neat if we had an indication of true heading even when the station
stopped and simply rotated around a point.
