Thanks, it did go away last night when I was driving around. But here's the thing. I have a 2013 Sport so have the rear view cam and not the compass. Maybe the compass is still in here but just disabled for the cam.The "C" typically means that the mirror needs to be calibrated. Find yourself a large parking lot and drive in a tight circle three to four times in a row in the same direction and that should restore the compass for you.
