Good morning everyone, looking for some expert opinions. I've had my 180C for about 6 months now and am trying to get the most out of the basic autopilot while working on my instrument rating. It has an STEC 20 (roll only) coupled with a 430W with a Nav/GPS switch. The wing leveler and heading bug work great, but I have tried all possible settings and have had had no luck getting it to track the GPS. The manual was no help. Any thoughts on how to fly a flight plan with the AP are appreciated, I'm pretty certain my issue is user error.
