What if your car radio quit working can anyone help?

Well, if it's not a fuse problem, it could be that your radio has indeed died. This happens.

Or, if you've had the battery disconnected lately, it could be that the anti theft protection has activated. Is there anything on the display at all? Any minute signs of life?

If you decide that the radio has passed from this world, into the realm of electron hell, don't despair.

I had to replace the factory Delco radio in my '96. I found one working like brand new on Ebay. As I recall, I paid $25 for it. Some fella was parting out a Grand Prix. Same radio as in the Sunfires. If you take this route, be sure that the radio you buy is unlocked, or that the current owner will include the pass code. Without one of those options, you'll have to pay a GM dealership a wad to get it working for you.

I just did a quick search on Ebay. There are about 30 radios for Sunfires, ranging in price from $9.99 to $30.
