Alright I just got a Grand Prix year 2000. I got a AM radio that I have put in but it will not turn on, I have checked the wires 3 times they are ALL hooked up right. I have tried 3 different radios and non of them work. I talked to a few friends and they said it might be locked up and idk what that means. If you guys can help me out with this I need to get this radio working asap
