Hi,
I just replaced the battery in my crysler concord which went dead. Upon getting my car back the radio was unable to play. I could change stations on the led readout but no sound or cd playback. I'm assuming theres a code to install to correct that problem. I purchased the auto used from a dealer & don't have any codes available. It's a factory installed radio by chrysler, what if anything can i do. Any help is greatly appreciated. Thanks Dan

 

well first of all inless this is a new car 2005 2006 you dont need a code something might have blown in the radio
