Video Screens Vehicle Speakers Only one audio source can be heard through the vehicle's speakers at a time. The audio source to be reproduced is specified by the A/V source selected on the driver's side head restraint monitor. The RSE system or an auxiliary device can be heard through all of the vehicle's speakers when a DVD or auxiliary device is playing and the radio is tuned to one of eight frequencies selected on the FM Modulator controller.
