Twice now in the past 3 days I've started up the car only to have music playing, but the NAV screen was completely black/blank? Shut the car off and start it back up and it works again. Anyone seen this before? I searched and found only one thread from 2005 with the same issue but it didn't provide much info.

I had this on my Infiniti! It took 5 trips to the dealership to realize that it was a SCREEN problem, not a radio problem. They actually changed out my whole radio, while all they needed to do was change out the screen. Power connection to your screen - the radio works fine.

There is a TSB on this mine was doing the sme thing they flashed the NAV and it hasn't happened since. Its TSB # 09-08-44-019

...happened to mine twice over a couple year period. I have had the TSB done performed and no issues since. Given how rarely it occurred before the fix, I do not know if the problem is actually resolved but GM does have a means of addressing the issue. So far I am pleased with the update.

Lou actually posted the TSB in this thread:

The fix does work: It hasn't reoccured since I had mine done. It takes about 10 minutes.

The problem is some sort of conflict that occurs when the NAV boots up and communicates with the data system.

Thanks guys! I'll have to get my car down to the service dept and have them flash my system.

Well, the first time I turned on my Nav, the look on my face was blank.
