Functional description

The RSE control unit can be switched on as of terminal 30B ON. After terminal R OFF, the RSE control unit can be switched on within the after-running period (approx. 30 minutes).

The control unit for the Rear Seat Entertainment system (= RSE control unit) is a bus user on the MOST.

The rear monitors serve as the display units for the RSE control unit. The images shown on the rear monitors are all created in the RSE control unit. The RSE control unit transmits all image information via APIX data cables to the rear monitors (APIX stands for "Automotive Pixel Link").

The radio module (standard Kleer) and the two aerials for the radio link to the wireless headphones are integrated in the RSE control unit. The radio module uses the 2.4 GHz radio link to transmit audio data with 2.37 mb per second in the uncompressed 16 bit stereo sound for a distance of up to 10 meters.

Depending on the version, the Professional rear seat entertainment system is controlled with the rear-compartment controller or radio remote control.

The signal path of the radio remote control corresponds with that of the remote control services. This means that the remote key signals are received by the aerial for remote key service. The signals are transmitted via the remote key receiver in the aerial amplifier to the Car Access System (CAS). The CAS outputs the signals as a message on the K-CAN2. The central gateway module (ZGM) is the data interface between K-CAN2 and MOST. The RSE control unit is a bus user on the MOST. The remote key that has been learned in for this specific vehicle is the only one that is operative.

When a DVD is being played in the DVD drive of the rear seat entertainment system, the image cannot be displayed in the central information display (CID). Display of the image via the rear monitors is also not possible if a DVD is being played in the DVD drive of the headunit. However, audio playback is possible in both cases. If a DVD is being played from a DVD changer, the sound and vision are output via the head unit and Rear Seat Entertainment system.

Depending on the version of the rear seat entertainment system, the volume is adjusted with the radio remote control or rear-compartment controller.

Audio playback takes place optionally over the speakers of the vehicle or headphones With audio playback through the speakers, the audio signal is sent by the RSE control unit via the MOST to the head unit or Top Hi-Fi amplifier. The volume of the speakers can be adjusted using the multifunction steering wheel, the controller, the rear-compartment controller or the infrared remote key. In the case of playback through the speakers, volume control is speed-dependent. Tone setting is also possible.

If audio is played back through the headphones, the volume is adjusted on the wireless headphones. For hard-wired headphones, the volume is adjusted with the radio remote control or rear-compartment controller. The wireless headphones receive their signals from the radio module in the RSE control unit. A maximum of 4 wireless headphones can be registered (see Owner's Handbook).

External audio devices and video devices can be connected to the cinch sockets and USB port. Operation takes place via the external device.

The TV receiver receives the TV signal via the TV aerial. The picture signals are transmitted from the TV receiver via a CVBS line directly to the RSE control unit. The TV receiver transmits the TV sound on the MOST bus. In the equipment version "Rear Seat Entertainment Professional", the RSE control unit has two inputs for CVBS lines that are assigned to the two sides of the RSE control unit (left and right).

The RSE control unit is connected to the Headunit High (HU-H) via Ethernet. The extended functions of Ethernet mean that high data loads are transferred quickly and in high quality to the Headunit High.
