Function requirements, general 

Rear entertainment system, general 

The rear entertainment system uses CD/DVD data storage devices to provide audiovisual entertainment for the rear passengers. An AUX connector, e.g. DVD player, MP3 player, video camera or games console can be connected to the rear entertainment system. For vehicles with code (863) Digital/analog TV tuner the rear passengers can also enjoy TV station reception.

The rear entertainment system comprises the following components:

IMPORTANT As of 1.6.09 the RCP (HBF) control unit functions are implemented using the IR remote control.

The rear entertainment system is enhanced by the optional use of the following components:

The following media sources are available to the rear passengers:

The DVD player and the rear displays are subscribers of the telematics CAN (CAN A) and communicate with the following control units:

For vehicles with code (810) Sound system or code (811) Advanced Sound System and code (863) Digital/analog TV tuner, data is exchanged through the following control units over the Media Oriented System Transport (MOST):

The rear entertainment system is operated through the controls on the remote control. Rear passengers can then select the menus in line with the menu guidance for each active rear display.

The control signals for the remote control are sent over IR interfaces to each active rear display or the SPLITVIEW display (A40/10).

The rear entertainment system also provides access to the active audio, AUX, video or TV application of the COMAND controller unit over the IR interface of the SPLITVIEW display. To this end, the IR remote control enables the media source of the COMAND controller unit for the rear entertainment system to be selected and activated in the menu of the currently active rear display.

The rear passengers basically have access to each media source of the COMAND controller unit, except the media interface. It is not possible however, to have front and rear passengers call up different media sources at the same time (except with code (518) Media interface).

Audio signals are sent over the IR interfaces or radio frequencies (as of 1.9.10) from the rear display to the headphones (cordless). If corded headphones are used, the audio signals are transmitted as analog signals from the rear display to the headphones via a cable. Rear passengers can also listen to audio on the vehicle's speaker system.
