The commands entered using the remote control of the rear seat entertainment are transferred via the transmission frequency, which is also used for the radio remote control key function. The frequency used is dependent on the national variant and therefore relevant for cod¬ ing. and therefore relevant for coding. The commands are received by the FBD aerial and routed via the antenna amplifierwith diversity module to the CAS3.The CAS3 converts the signals into K-CAN messages. The commands then reach the RSE control unit via the K-CAN. If audio is played back via the audio speakers in the vehicle, the audio signal is routed from the RSE control unit via the AUX_NF cables and via the audio socket to the radio or navigation system AuxJn.The audio socket is standard equipment in the E70 and fitted underthe center armrest. The connection to the RSE control unit is disconnected manu¬ ally by connection of an external item of equipments the audio socket. Other external items of equipment can be connected via the AV input to the RS E control unit. The programming, coding and diagnostics forthe rear seat entertainment are performed via the K-C AN. The terminal status is also transferred as a K-CAN message. 10 E70 Rear Seat Entertainment System Components Rear seat entertainment consists of the following components: • Rear Seat Entertainment (RSE) control unit with DVD drive, buttons and audio/video (AV) input for external equipment • Rear display with infrared transmitter • Headphone connection for infrared and wired headphones • Remote control.

The rear display is switched on by folding it up and turning it counterclockwise into pos tion.The RSE control unit is switched on when the reardisplay is switched on.Turning the reardisplay actuates a microswitch located in the swivel joint. The reardisplay is switched off by turning it clockwise or by switching the RSE control unitoff. Folding down the reardisplay does not switch off the RSE control unit, because the CD audio function must be maintained. The reardisplay photodiode aids brightness control. I nf ra red Tra n s m itte r The infrared transmitter consists of seven infrared diode and is located in the base of the reardisplay behind a Makrolon panel. The infrared transmitter is supplied with powerfrom the RSE control unit.The infrared diode therefore light up foras long as the RSE control unit can be activated oris active. The infrared diode go out when the RSE control unit is OFF and the run-on time of 30 minutes afterterminal R has switched off.. To insure perfect function of the infrared headphones, note the following: • Eye contact between the receiver on the headphones and the infrared transmitter • M akrolon panel on the infrared transmitter is clean and free from scratches. Remote Control The function LED lights up after actuation of each button to check the transmission func¬ tion. This confirms sending of a radio signal. The remote control signals are only convert¬ ed if the rear seat entertainment is activated. The thumbwheel, the confirmation button and the cross-control key represent the con- trollerfunctions. Turning the thumbwheel corresponds to turning the controller. Sliding the controllerto the left, right, forwards or back is replaced by pressing the corresponding button on the cross-control key. Pressing the controller corresponds to pressing the con¬ firmation button. The remote control only controls the rear seat entertainment.

Depending on the country, the remote control is available forthe following frequencies: • 868 MHz • 434 MHz • 315 MHz • 315 MHz low power. 19 E70 Rear Seat Entertainment Headphones Two infrared headphones are included with the RSE option. Wireless headphones can be purchased separately. Infrared Headphones Only approved BMW accessory/replacement IR headphones should be used on the E70. These can be ordered from the EPC. Volume control forthe IR headphones is on the headset itself. The carrierfrequencies of the infrared headphones are: • Left channel: 2.3 MHz • Right channel: 2.8 M Hz. There is no restriction regarding the maximum number of infrared headphones that can be used. Wired Headphones The connection sockets have a diameter of 3.5 mm. All commercially-available wired headphones with an impedance of at least 8 Q can be connected. Volume control for wired headphones is achieved via remote control or on knobs located on the RSE panel. Left and right volume controls for wired headphones are independently controlled. 20 E70 Rear Seat Entertainment Service Information Diagnosis The BMW diagnostic system contains the diagnostics for the rear seat entertainment under "Rear Seat Entertainment". Test plans and control unit functions forthe following components are available: • RSE powersupply • Rear seat entertainment control unit • Headphones • Remote control • RD powersupply. The RSE control unit and RD rear display are the control units available. Teaching-in the remote control There is a test plan forteaching-in the remote control in the diagnostics under Rear Seat Entertainment. The test plan works through the following steps: • The entry of the current detected remote control forthe rear seat entertainment is deleted in CAS3. • The remote control forthe rear seat entertainment is taught in. • Successful teaching-in of the remote control is acknowledged by the automatic closing and opening of the central locking. Note: Remote controls are not interchangeable. Only the taught-in remote control is functional in the vehicle. Programming and Coding The RSE control unit can be programmed and coded.The DVD area code can be changed during coding only if mileage is below 60 miles on the odometer. 21 E70 Rear Seat Entertainment DVD Area Code DVD area codes were introduced to restrict playback of DVDs to particular markets. As a rule, DVDs appear in one region before they do in another region. The earth has been divided into different regions and an area code has been assigned to each region: Area code Region Region 1 Canada, USA and US territories Region 2 Europe,J apan, Middle East, Egypt, South Africa, Greenland Region 3 South-east Asia including Hong Kong and South Korea Region 4 Australia, New Zealand, the Caribbean, Central and South America, Pacific Islands Region 5 FormerCIS states, Indian subcontinent, Mongolia, North Korea, Africa (excluding Egypt and South Africa) Region 6 China So that the area code functions, each DVD player is equipped with its own area code, determining for which market the device is intended. European devices are preset with area code 2, whereas American devices have area code 1. Each DVD can have one or more area codes, depending on the region(s) for which it is intended. Area code 0 identi¬ fies DVDs that are released for all regions. It is also possible that DVDs are released for particular regions, like 2, 3, 4, 5 and 6 - all countries excluding the USA. When inserting a DVD, the RSE control unit checks whetherthe region defined in the control unit matches the DVD country code. In this way, you can control which country the DVD can be played in. The RSE control unit permits a maximum of five area code changes, then the area code of the DVD most recently inserted is stored in the RSE con¬ trol unit. As a result, only DVDs with the area code defined in the RS E control unit can then be played. The number of changes still possible and the area code currently set can be issued in the BMW diagnostic system under RSE control unit functions. The area codes are set by coding the RSE control unit. Changing the area code in the control unit by coding reduces the number of possible area code changes. If changes are no longer possible, the control unit must be replaced when a DVD with a different area code is to be played. 22 E70 Rear Seat Entertainment
