Description
General
The DVD entertainment system can be fitted by Land Rover Special Vehicles as an original equipment system on the
Adventurer model or can be supplied as an accessory for fitment by the dealer. The system can be fitted to all
Discovery Series II models.
NOTE: The DVD system cannot be fitted to vehicles fitted with a Visteon single slot CD head unit.
The fitment of the system to vehicles manufactured before 2002 model year requires a different wiring harness and
connector plugs to vehicles from 2002 model year. Full details of components required for specific vehicles is
contained in the DVD System Accessory fitting instructions (Part No. STC 61947/61946).
The system comprises a main wiring harness, a lower wiring harness, CD switch box with integral noise filter, CD
switch harness, remote control handset and an overhead console containing the Liquid Crystal Display (LCD) monitor
and Digital Versatile Disc (DVD) player.
The system can play DVD films and display them on the LCD screen. The DVD audio can be played over the vehicle
audio speaker system or on headphones connected directly to the overhead console. The system can also function
as a second CD player. Rear seat occupants can listen to a CD in the overhead console via headphones, whilst the
remaining vehicle occupants can listen to CD's played from the CD autochanger in the normal way.

The overhead console unit is attached to a bracket which in turn is attached to a roof cross-member, to the rear of the
front sunroof. The cross-member is drilled and fitted with three captive nuts. The bracket is secured to the cross-
member with three Torx screws and provides the attachment support for the overhead console unit. The unit is
secured to the bracket with two screws located underneath the screen and two further screws which are located
beneath the button and plug trim panels.
The overhead console unit is connected to the main DVD wiring harness by a short link lead which has a connector
at each end. The main wiring harness is routed across the roof, above the headlining, to the top of the right hand 'B'
post and is then routed along the roof panel and descends down the 'A' post, behind the trim panel, to the CD switch
box next to the passenger compartment fusebox.

86-6-18 DESCRIPTION AND OPERATION
The console unit has three buttons which allow for minimum operation of the unit without using the handset:
lThe Stop/Eject button stops playback when pressed – 'Stop' appears on the LCD monitor as confirmation.
When the playback is stopped, a further press of the Stop/Eject button ejects the DVD or CD from the DVD
console – 'Eject' appears on the LCD monitor as confirmation.
lThe Play/Pause button begins play of the DVD or CD when pressed – 'Play' appears on the LCD monitor as
confirmation.
During play, pressing the Play/Pause button temporarily pauses the play – 'Pause' appears on the LCD monitor
as confirmation. A second press of the Play/Pause button resumes the play.
lThe Speaker button switches the DVD or CD audio to play through the vehicle audio speakers system. When the
CD is selected on the ICE head unit in the fascia, pressing the button allows the DVD or CD audio to play through
the vehicle audio speakers – 'Speaker On' appears on the LCD monitor. A second press of the button prevents
the DVD or CD audio playing through the vehicle audio speakers – 'Speaker Off' appears on the LCD monitor.
NOTE: These functions are also available from buttons on the remote handset.
Two sockets are provided on the left hand side of the unit and one socket on the right hand side of the unit for the use
of headphones with the overhead console unit. This allows the three occupants of the 2nd row seats to listen to the
DVD output using headphones. Occupants of the 3rd row seats can also listen to the DVD output using headphones
connected into the two radio/headphone amplifier units.
The console has three Phono sockets which allow for the use of an auxiliary video unit or video games console to be
connected to the system and use the LCD monitor for display. The sockets are colour coded for correct auxiliary input
connection as follows:
lRED – Right channel audio input
lWHITE – Left channel audio input
lYELLOW – Video input.
A slot is provided on the right hand side of the console for insertion of a DVD or CD into the console unit. The DVD
or CD can be inserted into the slot with the label side facing upwards. The DVD or CD is ejected from the slot when
the Stop/Eject button is pressed.
When the LCD monitor is in the lowered position, an infra-red receiver is exposed and receives transmitted signals
from the remote control handset. The receiver is located adjacent to the status LED which is illuminated when the
system is active.
The DVD player in the overhead console has an auto eject feature to protect the DVD or CD in the unit from damage
due to excessive heat. The status LED will flash to alert the user to this condition. If the temperature exceeds 70°C
(158°F), the DVD system automatically ejects the DVD or CD and shuts down, preventing further operation. When
the temperature in the vehicle has returned to 64°C (147°F) or less, press the 'Power' button on the handset or open
the LCD monitor to switch on the system.
Liquid Crystal Display (LCD) Monitor
The LCD monitor is suited for use with the in-car DVD system because of its compact, lightweight design and low
power consumption. The LCD monitor is a highly sophisticated unit and should be treated with care. Observe the
following precautions when using or handling the LCD monitor.
lDo not press on the monitor, this can distort the picture and cause permanent damage to the LCD panel.
lClean the LCD panel with a damp soft cloth with a mild household detergent if necessary. DO NOT use solvents,
commercial cleaners or anti-static sprays.
lDo not use the LCD in temperatures below 0°C (32°F) or above 80°C (176°F). If the vehicle is used in a cold
climate or in direct sunlight in a warm climate, the LCD monitor may not function correctly outside of the
temperatures stated. The picture may not be clear. This will not cause permanent damage to the monitor and the
picture should return to normal once the temperature is within the operating range as stated.

5Connector C07
The CD switch box is located below the steering column, on the passenger compartment fusebox bracket, behind the
fascia closing panel. The box is secured to the bracket with two metal clips.
The switch box is connected to the lower DVD harness assembly. Two plugs from this harness connect into the switch
box on opposite sides. A fly lead from one of the connectors provides for the connection of the integral noise filter.
Some CD switch boxes have two internal switches which are located next to one of the clips. This type of CD switch
box can be used on vehicles with either a Becker head unit or an Alpine head unit. The switches have two positions;
'Differential Audio' or 'Non-Differential Audio' which is defined by a decal above the switch aperture. For a Becker head
unit the switches must be in the 'Non-Differential Audio' position, for an Alpine head unit the switches must be in the
'Differential Audio' position.
CD switch boxes without the internal switches can only be used on vehicles with an Alpine head unit and cannot be
used on vehicles with a Becker head unit.

86-6-20 DESCRIPTION AND OPERATION
Remote Control Handset
The remote control handset is supplied with the system and communicates with the overhead console via an infra-
red signal transmission. The handset has 50 buttons which control all DVD functions, with the exception of the volume
control. Volume control is performed by the rotary control supplied with the headphones or by the Audio head unit
volume control for the vehicle audio speakers.
The handset is powered by two, AAA size batteries. These are located behind a sliding cover on the rear face of the
handset. Battery life is approximately six months depending on usage.
To prolong the life of the handset, observe the following precautions:
lDo not leave the remote control near any heat sources or in direct sunlight. Store the handset in the vehicle
glovebox or door pocket to protect it from direct sunlight.
lAlways replace both batteries at the same time. Do not use an old battery with a new one and avoid mixing
brands of batteries.
lEnsure that batteries are inserted correctly with the '+' and '-' symbols on the batteries matching the '+' and '-'
symbols in the battery compartment. Do not charge the batteries or use re-chargeable batteries.
lIf the unit is to be unused for along period of time, remove the batteries from the handset.
If battery leakage occurs, remove and discard the defective batteries in line with local guidelines. Clean the interior of
the battery compartment using a mild household detergent on a damp soft cloth.
