I made a mistake and bought the wrong the wrong cd changer for my crown jzs175 (which shares the same cd changer as lexus gs 300). The correct part has only 2 slots at the back for the connectors (see pic 1) while the wrong part (pic 2) has 2 slots plus an optical audio slot for the cd audio.
Since the car doesn't have an optical audio cable it means that there is no audio while playing the cds at the moment.
The radio works fine.

Is there a way I can interface the cd audio to the radio audio so I can get sound when playing the cd?

Bump please
