REAR SEAT ENTERTAINMENT MODULE
RSE Module
The Rear Seat Entertainment (RSE) module is located in the rear RH (right-hand) side of the luggage compartment. The RSE module interfaces between the audio and video inputs from other systems components and the video display and audio outputs.
The RSE module communicates with the audio systems via a MOST connection. Audio output from the DVD (digital versatile disc) autochanger and the AVIO panel is processed by the module and passed on the MOST ring to the audio amplifier to allow audio output to be played on the vehicle speakers or on the cordless headphones.
Video input from the TV tuner, DVD (digital versatile disc) autochanger and the AVIO panel is also processed by the module and passed to the two RSE LCD (liquid crystal display) screens and the TAD on separate video connections. The RSE module also controls the power supplies to the RSE LCD (liquid crystal display) screens and relays the infrared remote control signals received by the RSE LCD (liquid crystal display) screen infrared sensors to the DVD (digital versatile disc) autochanger. The infrared signals are passed from the RSE LCD (liquid crystal display) screens to the RSE module on a bus system known as the IS bus.
The DVD (digital versatile disc) autochanger outputs some of its information to the RSE module on an Alpine proprietary bus known as the Ai Net.
The RSE module has two modes of operation; engine running mode and reduced operation mode. With the engine running the RSE module has full functionality. When the engine is not running the RSE module has reduced functionality to prevent excessive drain on the vehicle battery. The reduced functionality comprises a reduced audio volume and time limit on system operation.
The reduced audio volume is only active when the engine is not running. The audio volume is limited to a maximum setting of 12 to reduce battery consumption. If the volume was set at a higher level than this when the engine was running, when the engine is subsequently started, the volume level will gradually increase to the previously selected setting. This prevents the user being distracted by a sudden increase in volume.
The time limit operation is active when the key is removed from the ignition and the system is manually switched on using the TAD. The system will operate for a maximum of one hour. The battery voltage is continually monitored by the IHU. If the IHU detects that the battery voltage has fallen below a predetermined level, the IHU will shut the infotainment system down to prevent further battery drain. Once the system has shut down due to low battery voltage, it can only be restarted when the engine is running and the battery voltage has risen above the threshold level for more than one minute.
The module is connected into the infotainment system with five harness connectors.

Two TV antennae are located in each rear side quarter window. The forward antenna is a high frequency antenna and rearward antenna is a low frequency antenna. Each antenna is connected directly to a TV RF antenna amplifier which located just above the rear quarter light, behind the trim.
Remote Audio Controls
Rear Seat Remote Audio Controls
The rear seat passengers can use standard headphones to listen to audio from any of the sources fitted to the vehicle. These include:
^ Television
^ CD (compact disc)
^ Radio
^ DVD (digital versatile disc)
The remote audio control modules are located in the rear doors, incorporated into the rear window switches.
The remote audio control modules allow the user to select which source to listen to. The remote controls cannot override what the driver has selected. If the driver is listening to a CD (compact disc) the rear passenger cannot control the CD (compact disc) player.
The remote audio control modules allow the user to alter the volume in the head phones, change track/disc up/down or repeat on a CD (compact disc), change pre-set radio stations or tune up/down on the radio and television.
DVD (digital versatile disc) Autochanger
The DVD (digital versatile disc) autochanger is located in the RH (right-hand) rear corner of the luggage compartment. The DVD (digital versatile disc) player is a six disc design which will accept DVD (digital versatile disc) movies, video CD (compact disc) 's (VCD) and music CD (compact disc) 's on CD (compact disc) -R or CD (compact disc) -RW. The discs are housed in a magazine to allow six discs to be stored in the unit. Additional magazines can be purchased to allow greater flexibility. The magazine is accessible via a sliding door on the front of the unit. An eject button, located behind the door, when pressed, automatically ejects the magazine from the unit.
The DVD (digital versatile disc) autochanger is operated using a remote control unit supplied with the vehicle. The remote control is an infrared unit which transmits the infrared signal to receivers in each RSE LCD (liquid crystal display) screen.
The DVD (digital versatile disc) autochanger receives the remote control information from the RSE LCD (liquid crystal display) screens on a bus system known as the IS bus to the RSE module. The information is then passed from the RSE module on an Alpine proprietary bus known as the Ai Net to the DVD (digital versatile disc) autochanger. The Ai Net is a bus system used to communicate between the RSE module and the DVD (digital versatile disc) autochanger.
A Sony Philips Digital Interface Format (SPDIF) is used to output the audio from the DVD (digital versatile disc) autochanger to the audio amplifier. The SPDIF is an optical system connected between the DVD (digital versatile disc) autochanger and the audio amplifier. SPDIF is a standard audio file transfer format which allows the transfer of digital audio signals from one device to another without having to be converted first to an analog format which maintains the viability of the digital audio signal.

Fault Finding
If the operation of the DVD (digital versatile disc) freezes or the screens do not display, turning the power to the unit off and then back on may clear the fault. Alternatively, change the source from DVD (digital versatile disc) and back to DVD (digital versatile disc), turn the ignition switch to off and then on again to position II. The following table gives possible faults, their causes and remedies.
Rear Screens
The RSE LCD (liquid crystal display) screens are located in the rear of the front seat head restraints. The screen is secured in the head restraint with three screws which are covered by a removable surround. The screen is a 6.5 inch, auto dimming, high resolution LCD (liquid crystal display) monitor, manufactured by Alpine
An ambient light sensor, in the bottom left edge of the screen, allows the system to automatically adjust the brightness of the screen to compensate for changes in ambient light levels.
An infrared receiver sensor is located centrally in the upper screen surround. The sensor receives infrared transmissions from the DVD (digital versatile disc) remote control and passes them to the DVD (digital versatile disc) autochanger, via the RSE module on a bus system known as the IS bus. All screen settings can be changed using the RSE remote control.
The screen should be cleaned with a lightly, water moistened cloth. Do not use chemical agents or domestic products to clean the screen or any part of the surround.
Each RSE LCD (liquid crystal display) screen is connected to the infotainment system using a 20 pin harness connector.
Remote Control
The remote control for operation of the DVD (digital versatile disc) autochanger is a universal infrared type. A switch on the rear of the control selects either the left hand or right hand screens and allows the individual settings for each screen to be changed as required. The switch has a central position which disables the remote control and prevents battery drain.
The remote control transmits an infrared signal in response to operation of a button. The signal is received by a sensor located on each RSE LCD (liquid crystal display) screen and is passed, via an IS bus to the RSE module. From the RSE module the signal is passed on an Alpine proprietary bus known as the Ai Net, to the DVD (digital versatile disc) autochanger. The remote control also allows selection of an auxiliary input from the AVIO panel (video or games console) or selection of audio (radio or CD (compact disc) ).
The remote control is powered by two 'AAA' batteries located in the rear of the control and are accessible by removing a sliding cover. When inserting the batteries it is important that the battery polarity is observed as marked in the battery compartment. LED (light emitting diode) 's at the top left and right hand corner of the control indicates that the remote control is operating when a button is pressed. Only one LED (light emitting diode) will illuminate depending on which screen is selected. If the LED (light emitting diode) 's fail to illuminate when a button is pressed, the battery voltage may be low or the switch on the rear of the control may be set in the central 'off' position.
Audio Vedio Input Output Panel
The AVIO panel is located at the rear of the center console. The panel provides for the connection of auxiliary audio and video inputs from an external source, such as a games console, via seven plugs on the panel. The plugs are covered by a lift up panel.
Two sets of video and audio phono plugs are provided and are designated as AV1 and AV2. The plugs are connected to the RSE module and allow the auxiliary input video to be played on the RSE LCD (liquid crystal display) screens and the audio to be played on the vehicle speakers or via the rear headphone modules. The auxiliary input video cannot be displayed on the TAD.
An additional single, 3.5mm jack plug allows for the attachment of an auxiliary audio input, such as a personal stereo or MP3 player. This plug is connected directly to the IHU and allows audio to be played on the vehicle speakers.
The AVIO panel is connected to the infotainment system using two harness connectors.
