radio unlock code for a 2001 pontiac sunfire

OK, generally, you have to go to the dealer and get this code. Sometimes, you can do it over the phone. But, you have to have proof that you actually own the car before they will do anything for you. I saw one message board that listed codes for Aveos radios, but I don't know if they really work as I've never needed them. But, I would check with a GM dealer, first.
