I tried searching for similar problems to no avail so I was hoping that somebody could help me out. Recently the battery died on my '06 G6 and needed to be replaced. I put a new battery in but now the time and temp on the radio display disappear about 15 seconds after you turn the car on. All of the radio functions still work and hitting the display button will bring it back for 15 seconds but then it goes blank again. The only item that doesn’t shut off is what source the radio is in (ex FM1). Even more odd is when you turn the car off it magically reappears until you open the driver’s door. Any assistance with this would be greatly appreciated.
