PURPOSE: A car AV(Audio and Visual) system is provided to prevent the reduction of AV system viewing feeling, due to an error in a communication line caused by a potential difference generated by electromagnetic disturbance or the difference of ground. CONSTITUTION: A video CD(Compact Disc) changer(1) plays a video CD, to output following electric signals through a transmission unit. A tuner(2) receives the signals transmitted from the transmission unit of the video CD changer through a receiving unit for processing, and outputs following electric signals through a transmission unit. An AV head unit(3) receives the signals transmitted from the transmission unit of the tuner through a receiving unit, and displays the received signals for the viewing of users. And an optical fiber cable(4) is connected between the transmission unit of the video CD changer and the receiving unit of the tuner and between the transmission unit of the tuner and the receiving unit of the AV head unit, and transmits signals output from each transmission unit to each receiving unit.
