Autopilot fails on Raytheon ST5000+ with "No Data" error

Hello, I have a 38ft (11.5m) sailing cruiser with a Raytheon ST5000+
autopilot, Raytheon radar/chart plotter with Wind, Depth, Speed, GPS,
fluxgate compass, etc.
The autopilot works only when travelning west. Attempting to calibrate
the system always fails at the "Turn Boat" phase with a "Too Fast"
error even thou I've done the turn dozens of times exactly by the
book. The ST5000+ compass heading is wildly inaccurate. As the boat
turns the ST5000+ compass display jumps in large increments rather
than smoothly as I would expect.
Tying the autopilot in any direction other than West results in a
change of direction or a "No Data" error.
Many thanks, Donagh.
I had some very weird problems with an AutoHelm compass caused by the
compass sensor getting hung up on its wiring or gimbals (inside the
sensor housing). I opened the sensor housing and made sure the sensor
itself was correctly positioned and free to move - _then_ I was able
to do the calibration, and the pilot worked.
