Jaguar XJ (X350). Manual — part 1307

Diagnosis and testing

Video System

Principles of operation

The rear seat multimedia system can provide audio or audio/visual entertainment independently to

the rear left-hand and right-hand passengers via personal headphones and display screens, or allow

output over the main vehicle audio system speakers, and allows the rear seat passengers to control

certain voice-activated functions, provided the multi-zone voice option is fitted.

There are three system levels:

Level One

Level one provides rear seat audio only, controlled independently of the main ICE control unit.

Level Two

Level two provides audio/visual capability, and allows the use of video inputs from a number of

sources, selected from the rear entertainment control panel:

•

TV tuner (where fitted)

•

camcorder (via auxiliary connectors in the rear entertainment control panel)

•

video games (via auxiliary connectors in the rear entertainment control panel)

•

any other external audio or video source compatible with the auxiliary connectors

Level Three

Level three provides all the functions of level two, plus DVD (located in the luggage compartment).

Each of the audio/visual sources above are switchable to allow the headphones/display screens to

operate independently of each other.

The rear seat passengers will be able to control the following units:

•

ICE head unit (tuner, MC, CD, and MD)

•

phone (where fitted)

•

multizone voice control (where fitted)

•

TV tuner (where fitted)

•

DVD player (where fitted)

•

auxiliary sources, 1 and 2

(connectors in the SRS system to the air bag modules). <<501-20>> For safety information on

disconnection of air bag connections.
