We just got a 2006 IS350 and everything but the CD player works. It's a non Mark Levinson/Nav system. I hit load and nothing happens. Nothing was mentioned on if the CD player works or not. It also doesn't indicate that there is a CD currently in there or not. Just dead. No response from it at all. I found a cable between the passenger seat and door right next to the seat belt that is not connected to anything and not sure what it is for :suspiciou. I checked all the fuses and all are fine. If anyone has any suggestions or what could be gong on with it, please help!!!
