I bought a flipout Pioneer head unit (touchscreen) from my friend for $100. He was selling his car so I wanted to get the hu from him before he sold it. But anywayz, it works and all, but it doesn't play cd's or dvd's...It is capable of, but obviously theres something wrong. So is there anyway I can get this fixed without it costing me a fortune? Or do something myself to get it to play dvd's?
