systems.

A typical example of information transfer is vehicle speed information from the ABS (anti-lock brake system) module used to
control the automatic volume control function. The vehicle speed information from the ABS module is sent on the high speed
CAN network and collected by the instrument panel gateway. The signal is passed to the medium speed CAN network and onto the ICM gateway. The ICM calculates the volume adjustment required. The corrected audio volume level signal is sent on the
MOST network to the IAM or Power amplifier (dependant on vehicle equipment level) for output to the speaker system.

AUDIO SYSTEM USER CONTROLS

Touch-Screen



Item Description 1 Touch-screen 2 Home menu button 3 Touch-screen on/off button The Touch-screen forms the basis of the audio system. It communicates with the rest of the audio/infotainment system on the
MOST ring and allows control of the audio system and other infotainment systems from a single point.

The Touch-screen communicates with the IAM on the MOST ring and provides the primary user interface and display of the
audio system controls. No configuration procedure is required if the touch-screen is replaced.

Calibration of the Touch-screen using the Jaguar approved diagnostic equipment enables updates to be downloaded as new
technology becomes available or any fault concerns require software updates.
The touch-screen provides user control of the following systems:

System Functions Audio Radio display AM/FM or DAB, auxiliary and portable audio, digital TV or CD (compact disc) Climate
control Air conditioning, distribution, seats, heated steering wheel, automatic air recirculation Telephone Digit dialer, phone book, last ten calls (made, received, missed) Navigation Destination, stored locations, navigation setup, route options Vehicle
Security, parking, valet mode, trip computer, clock, brightness, contrast, system settings, vehicle settings, display settings

Item Description 1 iPod connection 2 USB connection 3 Auxiliary connection The chosen audio device is plugged into the car using the interface panel located in the center console between the front
seats. Vehicles with the optional iPod function are supplied with a bespoke iPod lead in the vehicle delivery pack .

A menu option is available through the Touch-screen audio section when selecting a portable audio device for operation
through the vehicle audio system.

After the connection of an iPod or USB mass storage device the Touch-screen is used to operate and search the connected
device. Due to safety regulations, the normal control interfaces of either the iPod or USB device are disabled when it is
plugged into the interface panel.


NOTE: Some MP3 players have their own file system that is not supported by this system. To use the MP3 player it must
be set to USB Removable Device or Mass Storage Device mode. The manufacturer's information should include details of this
procedure. Only music that has been added to the device in this mode can be played via the vehicle's portable audio system.
Conversely, connection of any devices through the auxiliary connection cannot be controlled through the touch-screen and are www.JagDocs.com

the roof pod and is shared with the DAB (digital audio broadcasting) band L antenna or satellite radio antenna where fitted.
The roof pod is located externally in a central position towards the rear of the roof.

The GPS antenna is designed with 50 ohm output impedance. The navigation computer is fitted with 50 ohm fakra II connectors to ensure compatibility with the antenna. For optimum performance 50 ohm low loss coaxial cable is used between
the antenna and navigation computer.
It is possible for the GPS antenna to lose the signal from the GPS satellites; In hilly or tree lined areas
Built up areas with tall buildings
In multi storey car parks
In garages
In tunnels
On bridges
During heavy rain or thunderstorms

When the signal is lost the navigation computer will continue to give guidance using memory mapped data from the DVD map until the signal is restored.

TMC/VICS FM Antenna

Data messages for both TMC (traffic message channel) and VICS (vehicle information and communication system) are received
through the FM antennas and diversity antenna module located in the heated rear window.
VICS Beacon Antenna (Japan Only)



The VICS (vehicle information and communication system) beacon antenna receives infra red and RF (radio frequency) traffic
data signals from road side transmitters. The antenna is connected to the navigation computer which incorporates a VICS
(vehicle information and communication system) receiver.

Touch Screen Display


The Touch-screen is the control interface for the following vehicle systems;

System Functions Audio Radio display AM/FM or DAB (digital audio broadcast), auxiliary and portable audio, digital TV or CD Climate
control Air conditioning, distribution, seats, heated steering wheel, automatic air recirculation Telephone Digit dialer, phone book, last ten calls (made, received, missed) www.JagDocs.com
