Rearview compass failure?
Tried a site search but hoping someone might have experienced this... Suddenly the window with compass direction is just blank. Multiple starts and hasn't come back -- looks like the fuse is shared with some other things (that still work), so likely not a fuse issue. Per the manual, pressing the pinhole button calibrates/sets the magnetic variation, but no response doing that. No codes with a VCDS scan.
Has anyone had the rearview mirror fail like this? I can't tell if it's still auto-dimming as I've only had it out daytime lately. Any tips on what drives the compass? I recently had the ColorMFA update to the cluster, but the guy who did the update says the cluster doesn't drive the compass. It seems like a straightforward quick disconnect under the housing just prior to the headliner if I need to swap it out with a replacement mirror.
Thanks for any help!
