). Disconnect one. Then try powering up the car and audio system again. In my case, I can use the radio without CD once I found the right wire to disconnect. That is, if I disconnected one of the wires, the radio would not even turn on. If I disconnected the other, I could use the radio without the CD. And if I disconnected both wires, again nothing would work.
