Thread: Navigation unit installed date go bye bye. HELP!!!

I believe you are correct. I'm experiencing the same issue with my GXP. I need to replace my Nav antenna to restore time to the radio. It kept working until the battery dies. The car was in storage for 6 months. I had installed the factory Nav (Denso 15263106) from my previous Grand Prix and added a Kenwood antenna to get it to see the bird, but that antenna has died for whatever reason. Now I cannot set the clock on the radio of the date on the DIC.

So, why all this expense and effort to have less car than you bought? I keep asking this question, and I can never get an answer. Why is it that you people trust GM to build/source electronics that govern engine and transmission function, DoD, ABS, stability, etc., but you think they can't handle 1982 radio technology? What is the thinking there? And why do you want your car interior to be uglier?
