Well, I got this problem last winter as well. Whenever the out door temperature drops to below -10C there is a big chance that my rear view camera stops working when I put in reverse first start in the morning (I park my car outside). It doesn't happen everytime though...

The screen stays at NAV and just wont switch to the camera view. Everything works fine except the camera. This happened like 3 - 4 times last winter and still happens this winter. It will work again after the car warms up or on the second start. My dealer couldn't find anything wrong last time.

Has this happened to anyone else? What is wrong with it?

 

My camera has dew on it occasionally which sucks bec I can't see lol but no I never had this problem

 

Ok, anyone else???
