86-6-26 DESCRIPTION AND OPERATION

Connector C05
Connector C05 is located passenger compartment fusebox and supplies power and ground to CD switch unit.

Electrical Supply
The complete system is connected via a connection in the passenger compartment fusebox. A plug is connected to 
an auxiliary socket in the fusebox and supplies the ground, accessory power and permanent battery power supplies 
to the system via the CD switch and main DVD harness.

The system is connected by two fuses in the passenger compartment fusebox as follows:

l

Fuse 15 (20A) – Auxiliary power supply

l

Fuse 27 (15A) – Permanent battery supply.

CAUTION: Always replace fuses with a fuse of the correct Amperage rating.

Voltage Protection System
The DVD system has a voltage protection system to protect the vehicle battery from further loads if battery voltage is 
low or to protect the DVD system if the battery voltage is high.

 If the battery voltage falls to 11 volts or below, the system will shutdown to protect the battery from further drain. A 
message 'Voltage Error shutdown' will appear in the LCD monitor before the system shuts down. When the battery 
voltage reaches 11.5 volts or above, the system will restart when the power button on the remote control handset is 
pressed.

If the battery voltage exceeds 17 volts, the system will shutdown to a low voltage 'dormant' mode to protect the system 
from excessive voltage. A message 'Voltage Error Shutdown' will be displayed in the LCD monitor before the system 
shuts down. When the voltage has fallen to 16.5 volts or lower the system will restart when the power button on the 
remote control is pressed.

Pin No.

DESCRIPTION AND OPERATION 86-6-27

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:

l

If 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.

l

If 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.

l

If 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.

l

Speaker 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.
