I use the classic 172, and most liveries I download (either from the MSFS Market or online), my heading stops working. It’s the strangest thing, am I doing something wrong?
I install the livery, then get in the classic 172, choose the livery, and then I get up in the air, set a heading, turn on autopilot, hit the heading button, and nothing. I just keep going the same direction.
What does that even have to do with liveries anyway?
Much thanks,
I’m not an expert here, but I have read enough reports where developers have stated that if a livery (or other mod for that matter) includes its own panel.cfg file or updates it, it may overwrite items that break plane functionality.
This happened a lot to me on the CJ4 and DA-40NGX mods. Livery conflicts, light mod conflicts, etc.
Do you have any C172 Mods installed ??
I installed 172 liveries from the Marketplace on Xbox and found oddities similar to this; for me, it was COM1 and COM2 were coupled (as well as NAV1 and NAV2). That is to say, I couldn’t adjust NAV2 to get a bearing on that HSI without also swapping NAV1. Haven’t flown it since.
edit: Premium Deluxe steam-gauge version, obviously 
Yes, as noted, this happens when there’s a rogue panel.cfg or panel.xml file in the panel directory.
Contact the developer and have them fix it.
