IRRC the Rudder feedback calibration

. I think I would try both. Then select the menu item to Display the actual rudder angle
to compare with the AP28's.
If that fails, I would perform an Instrument reset
and start the rudder feedback calibration process again. I believe you might have to perform this procedure on each of the IS20's, but that's above my pay grade.
I no longer have that system on my boat as I changed out my entire electronics suite to Garmin, including the A/P. I miss the AP28 and particularly the FU steering lever a lot. Best autopilots I have ever used.
