Well, I have it back, and the dealer and the BMW tech both say the display is working as designed, that the tilt control for the display head is intended to help with the display settings....
I asked them to look at the display in a 5 or 7 Series, but I was told that was not a good comparison, the X3 uses a different display head..
Red, can you post a photo of your Nav display (either on a map display or the Settings page)? I'd like to see what someone else's system looks like. Maybe this is a temperature-related thing.
