I just installed a new Sony reciever and my factory 6 disc cd changer (F5FF-18C830-AA) doesnt work. I thought that it was simply connected through the antenna, but the controller for the reciever will not power up. Did I not connect something properly or will the reciever simply will not work with the changer? I am thinking it may have something to do with bypassing the factory amp? HELP!

You MUST use a Sony CD changer to interface with your new receiver. You cannot use the factory changer except with the factory controller.
