Play your music through your PIONEER head unit (must have PIONEER IP-BUS CD changer input) | Hear your music in much better quality then other iPOD connections | You can't connect a CD Changer to the head unit at the same time while this cable is connected. | Just plug one end of this cable into the CD changer input in the back of your stereo and the other end to the mini jack input on the device. | Control and display remain on the audio device -- the PIONEER headunit will NOT control or display text
