Rear seat entertainment module (RSE)/DVD player




Rear seat entertainment module (RSE) is the central unit in the system for rear seat entertainment.
The control module is integrated with the DVD player and is located at the rear edge of the center console.
The control module interprets and carries out the commands given by the user using the system's infra red remote control. These commands are then forwarded from the remote control to the Rear seat entertainment module (RSE) via the system's infra red receiver in the screens. The Rear seat entertainment module (RSE) also distributes current to the system's other components.
The Rear seat entertainment module (RSE) distributes audio and video signals from the DVD player to screens and loudspeakers in the system. Other audio and video sources can be connected via external inputs (the AUX panel), such as games consoles and video cameras etc.
The DVD player mechanism has an anti-shock system and it helps to prevent the image or sound skipping when played. The DVD player has slot-in disc insertion and region coding programmed into the software. The region code can be changed using a security code.

The following media formats can be played by the DVD player:
- DVD-R/+R
- DVD-RW/+RW
- CD-R and CD-RW
- CDDA
- HDCD

The following information formats can be played:
- DVD
- DVD Audio
- VCD
- SVCD
- DivX
- WMV
- Audio CD
- Kodak photo CD
- MP3
- MP3 Pro
- playlists in M3U format
- WMA Sound.
Formats such as THX and DolbyDigital are also supported. Only stereo signals of this audio format are reproduced.
The control module is supplied with power from the Ext.X-supply in the Central electronic module (CEM) and directly from the battery.
To easily check whether the control module is powered and grounded, switch on the ignition. The background illumination on the function buttons should then come on.

Change of DVD player region code
The region coding means that only discs with the region code matching that of the DVD player can be played.
The region code in the DVD player can be changed up to 10 times. After the 11th change, the set region will then be locked and it will not be possible to change again.

Note! Warranty repairs due to locked region on the DVD player will not be approved. Region code changes to the region in which the vehicle will be used is to be done at the workshop. The security code is not to be given to the customer.Do as follows to open the menu for region code change:

Model year 2006:
1. Switch on the system
2. Open the menu: SYSTEM MENU , SETUP , SERVICE MENU
3. Enter the code: 1971 and press ENTER

Model year 2007-:
1. Switch on the system

Note! There must not be a disc in the DVD player.

2. Aim the remote control at a screen and depress the button for child lock for approx. 5 seconds. The menu SYSTEM MENU will be displayed with four stars underneath.
3. Enter the code 1971 using the arrow keys on the remote control and then press OK.
4. Select menu selection REGION CODE and press OK.
The submenu can then be used to select a new region for the DVD player.

Rear audio separation module (RAS)




The rear audio separation module (RAS) is enclosed in a ribbed aluminum casing with installation holes.
The task of the Rear audio separation module (RAS) is to distribute audio from various audio sources to the vehicle's rear loudspeakers.
The Rear audio separation module (RAS) is supplied with power from the Rear seat entertainment module (RSE).
To check whether the rear audio separation module (RAS) is powered and grounded, switch on the ignition and then switch on the rear seat entertainment system.
You must then use the remote control to activate the sound to the rear speakers.
When the function is activated, there is an audible click from an internal relay in the rear audio separation module (RAS).

Screen, head restraint





The multimedia head restraint consists of five main components:
- Screen
- Circuit board
- Rear piece
- Border
- Head restraint pad
The rear piece is fastened in an opening on the rear of the head restraint pad. The circuit board is held in place in the rear piece with three screws. The screen is housed in the rear piece in front of the circuit board and is connected with a flexible foil cable and an AC lead. The border holds all electronic components in place in the rear piece in the head restraint pad. The lower edge of the border contains a window so that the infrared receiver on the circuit board can receive infrared signals from the remote control. The infrared receiver is separately connected to the rear seat entertainment module (RSE) and is activated when the rear seat entertainment module (RSE) is on.
The 7-inch screen in the head restraint has an aspect ratio of 16:9. The screen is positioned to provide the optimal viewing angle. The screen has a 120 degree horizontal viewing angle.
The integrated infrared receiver is activated when the rear seat entertainment module (RSE) is supplied power. The screen is not activated until it receives a high signal from the rear seat entertainment module (RSE)/DVD player via the wake-up cable.
This signal is sent when the system is switched on with the POWER button on the remote control or with the POWER button on the control module.
The circuit board contains an image generator, infrared receiver, infrared transmitter and the unit that controls all screen settings:
- colour
- contrast
- brightness
- aspect ratio.
The damping control has a damping ratio of 30:1 to improve the image and reduce bright light from daylight conditions down to complete darkness. Brightness can be adjusted so that the screen's image can easily be seen in daylight. Voltage protection and current supply of the background lighting also occurs via the circuit card. The control module contains logic for interpreting the command for setting the video performance, input selection and strength of background lighting. The control command is transmitted from the Rear seat entertainment module (RSE) via a private CAN network.
Each screen has an integrated infrared transmitter to send audio signals to the supplied wireless headphones. On the AUX panel, on the rear of the center console there is also an output for connecting headphones with leads.
The screens are supplied power and grounded via the rear seat entertainment module (RSE).
To check whether a screen has power and ground, you can switch on the ignition and then switch on the system with the remote control. The screen will then come on.

Note! If there is power and ground to the screen, but the screen does not have contact with the rear seat entertainment module (RSE)/DVD player, the screen will come on in LOCAL mode nonetheless. This is no guarantee that the entire system is operational.For more information, see the section Diagnostic functions/Fault-tracing information.If the screen works in LOCAL mode this indicates that the voltage supply and ground to the screen's circuit board are OK.

Remote control




The remote control is used to control the Rear seat entertainment module (RSE)/DVD player and the screens.
The remote control has 22 buttons; 1 red button and 21 white buttons.
The remote control uses infrared signals (IR) to transfer commands to the system. The signals are received by the screens' infrared receivers.
The remote control is equipped with two batteries, fitted under a cover at the rear.

Headphones




The wireless IR headphones can be used with both screens. IR transfer is used to transfer standard audio to the headphones in two-channel stereo format. The headphones are powered by internal batteries. The headphones are switched on with a button on one side while the volume of the respective headphones is adjusted with a wheel. Each set also has a channel selector that controls which audio source the set of headphones receives.
The audio from the left screen is always transmitted on channel A and the audio from the right screen is always transmitted on channel B.

External input (AUX)




On the rear of the center console there is an AUX panel with external input terminals for audio/video. This input can be used for supplying standard AV signals to systems, such as, video cameras, video game consoles, VHS videos, portable DVD or CD players.
All inputs on the AUX panel are directly connected to the rear seat entertainment module (RSE)/DVD player.
Two headphone sockets for connecting headphones with wires are also on the panel, one for the left-hand screen and one for the right-hand screen.
