Sound output takes place either through the vehicle's speakers or via headphones. The volume of the speakers can be adjusted via the multifunction steering wheel, the head unit or with the radio remote control. The volume is controlled speed-dependent during playback through the speakers. The driving speed is registered by the wheel speed sensors.
The tone settings can be adjusted on the Car Information Computer or Car Information Computer Basic or using the radio remote control.
If the sound is output via the headphones, the volume can be adjusted either on the headphones (infrared headphones) or using the radio remote control (hard-wired headphones). The infrared headphones receive their signals from the infrared transmitter.
External devices can be connected via the two AV inputs directly to the RSE control unit or via the AUX-In connection or the USB audio interface (option 6FL) in the center console. The USB audio interface provides an additional jack and a USB connection for a type A USB connector.
Video cannot be transmitted to the rear seat entertainment system when a DVD is played back via the Car Information Computer. Similarly, video is not transmitted to the Car Information Computer when a DVD is played back in the rear seat entertainment control unit. Sound output, however, is possible in both cases. Picture and sound are transmitted to the CIC and the rear seat entertainment system during playback via the DVD changer. For safety reasons, no picture is shown in the Central Information Display while the vehicle is being driven. Sound output continues even when the car is not at a standstill.
An external device (e.g. game console) can be additionally connected via the AV inputs. The corresponding video signal is output on the display of the connected source. The selected DVD can still be viewed on the other display. Prerequisite: see Functions, Connection to external equipment via AV input.
The RSE MID control unit has a FBAS/CVBS (composite video baseband signal) input for the screen of the DVD changer or video module.
The video switch is installed corresponding to the equipment configuration.
