Help! NAV screen in cold weather

[mylotcat]

Re: 2007 Coupe w/NAV. When the car has been sitting in cold weather, say 40s and below, after starting the car the NAV screen is 'blank'. I let the interior warm up and then expected the screen to 'come on,' but it did not. After turning off then restarting the car the screen worked. Tried searching for this on the forum and the web but didn't find anything. I'm going to call the dealer, but before I do I was wondering if anyone else experienced this? If it's in the NAV manual I didn't find it :eyerole.

Thanks...Dave

HI there,
There is nothing that I can see as far as GM documents.
However, do you even get the clock or does it light up at all????
Allthebest, c4c5

Thanks for the reply!

I get nothing...the screen is totally blank: no clock, no nothing. The radio plays but no display. Cycling the raido on/off does not help. However, after running the car for awhile, shutting off the engine, and restarting the engine, the display works.

I called the dealer and they think it's defective so, come good driving weather I'll take it in for them to evaluate. The service advisor said it sounds like the appropriate computer isn't sending the signal to "energize" the display.

Thanks again...Dave
