Hi! My wife just got a 2009 Q7 without a manual.

The interior rearview mirror is driving me batty! I get weird messages, such as 3, 3N, 3S, M, MS. I have not yet seen either an E or a W on this one.

I tried to calibrate it by holding in the off button. It showed an 8 which is the correct zone, but then it gave me a bunch of various letter/number combinations, eventually ending up with M.

Any ideas?

 

Never mind! Some idiot installed the mirror upside down! I turned it over, calibrated it, and it works perfectly.
