I am adding some more data here on testing today. I ended up deleting all Carenado planes and 2 other addons, completely removed all Community files, ran SimStaller which said WT 530 had an issue. I had deleted the standard ‘deleteable’ GNS530/430 system, tested, and AP’s worked. Reinstalling all planes, installing my Trinidad from Marketplace (compiled MS version) and reinstalling the second Version 1.1.4 GNS530/430, my Trinidad Autopilot began functioning. I did not test NAV/GPS linking, but the AP could hold ALT, HDG, and LVL. That was nice, and with screens working. But… Asobo Cessna 172 Classic AP is still not working. No HDG, ALT, etc.
I hope that helps.
