Whe I bought my 1999 vette a few weeks ago it came with a 12 Disc CD Changer (I think its made by Pioneer). When I try to play a CD my tape deck says Error. I also know that before I bought the car a new battery was installed. Could the changing of the battery cause some "codes" to be lost, and thats why the disc changer is not working. And if that is the case, how do I get it to work again?

P.S. I am instering the CDs correctly and they are store bought not CD-Rs
