I live in just south of Philly and a few morning my nav screen did not turn on when the car started..it was totally black. After putting it park and drive a few times it came on. This happened a few times. Also I noticed that when I put it in drive from reverse the rear view camera stayed on. Anyone else had similar problems? is it just the cold electronics?

 

I'm in NYC and I haven't had that problem. It's possible that is weather related, but it could also mean malfunction. Hard to tell. Check the manual, it lists the minimum and maximum temperatures needed for proper function.

 

I live where it really is cold - Minnesota. I never have seen any electronics problem in the cold. Go see your dealer.

 

I've been experiencing similar issues in my 07 g35x - on cold mornings the screen is blank, and it doesnt turn on unless i restart the car. Given the intermittent state of the issue the techs at my dealer havent been able to repro nor resolve the issue unfortunately...
