My daughter has bought and had someone that did not know what they were doing install a new cd player in her car.The biggest problem is that there is no memory wire so when she cuts the engine off the radio looses all its stations. l was told with the original plug that he should have used an adapter and everything would have been lovely.

easiest place to shop and find what you need would be crutchfield.com

Walmart actually has a good selection of car audio stuff l got my wiring harness there ..you can check any local auto parts store too good luck
