It plugs into any Sony stereo with CD/MD changer controls, activating the audio input jacks. When you select the CD/MD changer as the source, you can listen to any auxiliary source that's connected to the stereo's RCA inputs.This cable makes it appear that a CD changer is connected to the Unilink connection on a Sony head unit with CD changer controls.
