Andrew,

The DG is merely
providing HEADING information (ie. the setting of the bug).


And that is autopilot specific. We had to get a certain model of
Sigmatek DG for it to work with the STEC-50. Also, we now switched to
another model, which also delivers bootstrap heading info like a remote
compass would. We need that for the WX-500 we installed.
