Inputs and outputs
The radio cassette player receives a mute signal from the telephone system if a call is received, when the call finishes
the mute is removed and the system resumes play. Inputs are also received from the steering wheel control system
(mid line and high line sytems). When the system is turned on, the high line systems radio cassette player:
lsends a 'power on enable' to the power amplifier
lsends an 'enable' signal to the radio headphone amplifiers.
On the high line system the radio cassette player also sends and receives signals from the CD-autochanger and rear
headphone amplifiers (if fitted). On high line systems the radio cassette player sends audio signals to the power
amplifier.
Remote radio steering wheel controls (midline and high line systems)
The remote radio control switch is located on the LH side of the steering wheel and is secured with two screws. The
wiring from the remote radio control switch plugs in to a connector that is part of the steering wheel rotary coupler.
Operation of the remote radio control switches allow the driver to control the ICE without releasing the steering wheel.

Aerial
On base and midline ICE systems an AM/FM aerial is built-in to the side window glass on the RH side of the vehicle.
An amplifier is located on the frame above the rear side widow behind the rear quarter trim, and is secured (and
earthed) with one bolt. Coaxial leads connect the aerial to the aerial amplifier and radio cassette. Power is supplied
from the auxilary relay in the engine compartment fuse box, through a fuse in the passenger compartment fusebox to
the amplifier.
On high line ICE systems two amplified aerials are built-in to the side window glass of the vehicle. The two aerials are
an AM/FM aerial on the RH side, and an FM aerial on the LH side. The amplifier for each aerial are located on the
frame above each rear side widow behind the rear quarter trim, and are each secured (and earthed) with one bolt.
Amplified aerials improve the reception quality, the FM aerial gives improved reception in areas of poor signal
(diversity) conditions in urban areas. A Power feed from the radio cassette player is connected to the amplified aerials,
power is available when the cassette player is operating. The aerials are connected to the radio cassette player by
two coaxial cables, a small plug connects the FM only aerial, a larger plug connects the AM/FM aerial.
Power amplifier (high line system)
The amplifier is located on a bracket under the LH front seat and is secured with three screws and washers. The
amplifier receives inputs from the radio, radio cassette player or (via the radio cassette player) the CD-autochanger.
Power for the amplifier is supplied from the passenger compartment fuse box. The amplifier will power up when an
enable logic signal is sent from the radio cassette, this signal is sent by the radio cassette when it is turned on.
CD-autochanger (high line system)
A CD-autochanger is located under the RH front seat, the unit is secured to brackets in the floor with four screws and
washers. A tray is used to hold each compact disk (CD), the loaded tray is then inserted in a magazine, the magazine
holds six trays and is then inserted into the CD-autochanger. A sliding cover protects the internal components of the
CD-autochanger from dirt entry through the magazine opening. An eject button located on the front of the CD-
autochanger can be used to release the magazine from the CD-autochanger. The sliding cover has to be opened
manually before the magazine eject button is pressed. The operation of the CD-autochanger is controlled by inputs
from the radio cassette, the control inputs can be from the radio cassette buttons, the remote radio controls or the rear
radio headphone amplifiers if they are fitted. The output from the CD-autochanger are connected to the radio cassette
player. The radio cassette player sends the outputs to the power amplifier. Power is supplied to the CD-autochanger
by a feed from the radio cassette player.
Radio headphone amplifiers (high line system)
The rear mounted radio headphone amplifiers are located in the lower rear quarter trim casing and are held in position
by a clip on the side of the headphone amplifier. Mode and function buttons are located on a control panel, the mode
button allows each of the rear seat passengers to independently select from the radio, tape or CD-autochanger. The
driver and the rear seat passengers can each listen to any of the audio devices they select. However the radio
cassette setting has overall priority e.g:
lIf the radio cassette is using a radio wave band (AM or FM), the headphone user will be able to select the cassette
tracks or CD-autochanger. The user will be able to listen to same radio band that is selected on the radio
cassette, but will not be able to change the station selected.
lIf the radio cassette has CD-autochanger selected, the headphone amplifiers will allow listening to the compact
disk but will not allow track changes. The headphone user will be able to select on all of the radio bands or
cassette tracks.
lIf the radio cassette has tape selected, the headphone amplifiers will allow listening to the tape but will not allow
track changes. The headphone user will be able to select all radio bands or CD's on the CD-autochanger.
If one headphone amplifier unit has control of the tape player, CD or radio, the other headphone amplifier will be able
to listen and be able to change tape tracks or radio bands. Other buttons allow a search seek function of radio band
or compact disk track, reversal of the tape, radio station and volume adjustment depending on the current operating
mode. If one radio headphone amplifier has control of the radio, tape or CD autochanger the other radio headphone
amplifier is able to change the track or radio band selected. A headphone socket with a glow ring is located on the
control panel. When a headphone is turned on , a 'headphone-module active' signal is sent to the radio cassette
player. The design incorporates panel illumination and a glow-ring to locate the socket in low light conditions. To
control the audio output from the radio headphone amplifiers, signals are sent to and received from the radio cassette
player.

Operation
DVD Player Functionality
The following defines the functionality of the unit. Further details of system operation can found in the DVD System
Owner's Manual, Publication Part No. LRL0482, supplied with the system.
DVD Region Selection
The DVD player is capable of playing discs from any region. The DVD can only be set to play discs of one region at
a time. A code is entered using the remote control handset to set the unit to the required region. The unit is set to the
correct region on production and therefore this will not be required by either the dealer or the customer.
If the unit region is required to be changed for any reason, Land Rover Special Vehicles must be contacted for the
required code and procedure.
NOTE: The unit can be re-configured for region up to five times. After the fifth attempt to re-configure the region, the
unit will be locked in the fifth region that was programmed. This will require the unit to be returned to the manufacturer
to be reset. The manufacturer will charge a fee for this service.
DVD Player CD Audio Function
The DVD player can play audio CD's through the vehicle audio system. This allows the user to play additional CD's
without having to remove the CD autochanger cartridge.
The overhead console LCD monitor must be open to play audio CD's.. Normal audio CD functionality such as repeat,
random and track select etc. can be accessed using the remote control handset.
The DVD player in the overhead console will also function independently of the vehicle audio system, and operate as
an additional CD player. The rear seat passengers can listen to audio CD's via the three headphone sockets on the
overhead console and via the two radio/headphone amplifier units (if fitted), while the front seat passengers
simultaneously listen to CD's played on the vehicle audio system and CD autochanger.
DVD/CD Output using the Vehicle Audio System
To play the DVD/CD audio output from the overhead console through the vehicle audio speakers, the speaker button
on the overhead console or remote control handset must be pressed. 'Speaker On' appears on the LCD monitor and
the head unit CD functionality is suspended. The audio output from the overhead console will now be played from the
vehicle speaker system. The head unit volume control, tone control, Navigation announcements and mobile phone (if
fitted) will function as normal and override the DVD output. A second press of the speaker button will switch the audio
output back to the head unit. 'Speaker Off' will be displayed on the LCD monitor.
The overhead console will remember the selected speaker condition if the overhead console is switched off by closing
the monitor, the console switched off using the handset or accessory power removed from the overhead console.
Power Up Conditions
On application of accessory power, the overhead console will perform the following:
lIf no disc is in the DVD player, the LCD monitor will display a blue screen and enter 'AUX' input mode.
When a DVD or CD is inserted in the DVD player, the system will change to DVD input mode. The disc will
attempt to play but may be limited by the disc media. Some discs will play automatically, some will display a menu
and others require the user to start playback.
lIf a disc was in the DVD player and the system was in 'Play', 'Pause', 'FF' or 'Rew' when powered down, playback
will start when power is re-applied.
lIf a disc was in the DVD player and the system was in 'Stop' when powered down, the system will enter DVD
mode and a blue screen will be displayed on the LCD monitor.
lSpeaker selection will remain in the same state as when the accessory power was removed.
Engine Cranking
If the unit is playing a DVD or CD when the ignition switch is moved to position III (engine crank), the system will stop
playing while the engine is cranking. Playback will resume at the point the playback was stopped when the ignition
switch is returned to position I or II.
