    I am wondering why my radio would just stop working? I have removed it from my van and noticed the back has two different hook ups and was wondering why that was and if any other cd radio could be replaced that uses the same wiring plug that was used for my delco radio. The part no# is 09376162 if that is of any use. I have a 1999 Pontiac Montana van that this radio came out of. It worked fine until my battery died now it will not come on at all, but the lights still light up, except for the time and station display part. I’m guessing that is separate from the radio.
    Thank you for your assistance in this matter.

    Cynthia, it sounds like your car radio may be anti-theft mode. Most late model cars have radios that do not power up after the constant battery power to it is interrupted. This is an anti-theft feature in case someone steals your radio. Our advice is to have your local Pontiac dealer take a look at your radio. Hope this helps. Good luck.
