I've been using the Reality XP GTN 750 in a few XP11 airplanes, and it's a great piece of kit with one exception. When I couple the autopilot to the GTN's GPS guidance, the airplane will initially follow the GTN flight plan course. It will approach a waypoint and make the correct turn, but on coming out of the turn, the green "GPS" is no longer annunciated on the PFD and the airplane wanders off course. The autopilot remains engaged but later guidance is lost; it's not in heading mode or GPS mode. If I then re-engage GPS, things will be fine until the next turn.
I'm having this issue with the Aerobask Diamond 62 and several other airplanes as well. In the XP plugin window, I've got "Master Device" selected. But I think I've messed up a setting somehow. Any advice on this would be appreciated. Thanks.
