Good morning from Estonia 
Last year, we bought a nice Piper P28-180, which had already installed a G5 HSI with CAD29B and was also working with Autocontrol IIIB in heading mode. Now after an upgrade with a second G5 AI and GTN 650 the Autocontrol works only in GPSS mode (perfectly), in heading mode it starts to oscillate (when I turn GPSS off from HSI). Have I understood it correctly, I change from GPSS to heading mode only from HSI and it should follow the heading bug, when Autocontrol is on and in heading mode?
Regards
Erki
