I have the Century IIIb autopilot along with the 1C388 radio coupler along with a Garmin 430 GPS. All has worked well for approx. three years - on the latest flight, the autopilot would not follow the magenta line. When I switch the radio coupler to the Heading setting....it does not follow the DG "bug" nor does the autopilot follow the setting either in the Nav or OMNI mode.

Anyone run into this scenerio?
