Sorry. I may have missed somthing on the pilot manual.
I am sure during the first flights AP roll worked well, included the HDG function. That was after having set the GPS signal on the SV on NMEA output.
Now, only the level "button" appears. I have no way to control the AP via the magnetic knob.
I read that if system loses GPS TRK ceases to work. If loses magnetic, HDG ceases to work.
How could mine stopped to work on both TRK and HDG?
Thanks.

A bit stumped here. If the roll servo were disconnected or unpowered, you wouldn't be able to engage either of those modes, but the flight director would still be available (if in expert mode). If you are in simplified, a lack of GPS source would disable both TRK+ALT and HSI+ALT mode (there is not HDG mode in simplified mode). Pictures of your display in this configuration might shed light on things.

One other things that could cause this - if you were outside of the autopilot speed engagement range, you also wouldn't be able to engage either of those modes.

Thank-you.
I tried again and it works, now. Maybe it lost gps signal, the time before.
Thanks.
