Of course part of it may be that your boat's design is better able to hold a line than mine.
Ken, I actually have the AP20, but believe the computer is the same with a different display / control. I'm out of town for the week, but can walk you through the parameter adjustments when I have the manual in front of me. There are 2 or 3 parameters in a sub menu that adjusts response time (how far off course), rate of response, and over correction. It takes some time making adjustments and seatrialing to get it dialed in, but it's a amazing how well my boat now holds course. I can now drive it down the Dismal Swamp canal (<100' wide) on autopilot with only occasional corrections for magnetic variations along the canal.
While this thread was started for satellite compass, there may be some useful information on your system in the thread.
I'm tired of fast moves, I've got a slow groove, on my mind.....
I want to spend some time, Not come and go in a heated rush.....
