player is only compatible with standard CD's. All other versions of CD player are compatible with standard CDs and CDs with MP3 or WMA (windows media audio) files.

A portable audio module allows for the connection of a range of portable audio devices to the car’s audio system. The portable
audio module is controlled through the IAM (integrated audio module) and Touch-screen with play back through the car’s
speaker system. The introduction of this system allows the user to import their personal portable media player to interface
with the car, including iPod and other MP3 players, or USB mass storage devices such as memory sticks. MP3 players can also
be controlled through the Touch-screen if they are configured as mass storage devices. Details of how to do this will be
contained in the manufacturers instructions.

The chosen audio device can be plugged into the car using an interface panel located in the floor console between the front
seats. The interface includes a 3.5mm auxiliary jack-plug socket, a 12-volt power supply, a dedicated iPod connector with
charging function, plus a USB2 connector which allows connectivity for a wide variety of USB devices. The USB port also
provides a charging function although it does not support a USB hub. The maximum charging current supplied is 500ma. The
user can connect an iPod and USB device at the same time, changing the source via the Touch-screen. The non selected source
will still charge.

The Jaguar Sound System is the basic audio system which comprises of an IAM (integrated audio module) with no external
amplifier and 8 speakers.
The Jaguar 320W Premium Sound System has the addition of an AUD 8 power amplifier and a 9 speaker system.

The Bowers & Wilkins 440w Surround Sound System additions include an AUD 12 power amplifier, a Dolby Pro-Logic 2 7.1
Surround Sound System, and 14 speakers.

DAB (digital audio broadcasting) is available for most European markets and gives access to digital radio channels for better
sound quality and enhanced functionality depending on local service availability. The DAB (digital audio broadcasting) module
is located in the luggage compartment. The system receives reception signals from the following sources to ensure optimum
signal strength.

DAB band L antenna located in the roof pod antenna module
DAB band III antenna located in the heated rear window.

For NAS vehicles the digital format adopted is satellite radio which specifically links to the Sirius network. The system operates
in the S-band frequency range, and as a result of the use of satellite transmission, has the ability to provide CD quality audio broadcasts over very large areas (typically continents). The satellite radio receiver is located in the luggage compartment. The
system receives reception signals from the satellite radio antenna located in the roof pod module.

Primary user control of the audio system is via the ICP (integrated control panel) and the Touch-screen which are located in the
center of the instrument panel. Control signals from the ICP (integrated control panel) are relayed on the medium speed CAN
(controller area network) bus to the ICM (information control module). The ICM (information control module) relays the control
signals to the rest of the audio system on the MOST (media oriented systems transport) ring. The ICM (information control
module) is the timing master for the MOST (media oriented systems transport) ring and also hosts a gateway function between
the medium speed CAN bus and the MOST (media oriented systems transport) ring. Audio output signals on the Jaguar 320W Premium Sound System and Bowers & Wilkins 440W Surround Sound System are sent on the MOST (media oriented systems
transport) ring from the IAM (integrated audio module) to the power amplifier for speaker output. www.JagDocs.com

AUDIO SYSTEM OPERATION System Operation

The components of the audio/infotainment system are all connected on the MOST (media orientated systems transport) ring.
The MOST (media orientated systems transport) ring is a fibre optic communications bus for multimedia applications. Audio
and control information is passed around the MOST (media orientated systems transport) ring and can be picked up by any of
the systems units. For example, radio station tuning/selection input by the vehicle user into the Touch-screen is sent along the
MOST (media orientated systems transport) ring and collected by the IAM (integrated audio module) which then selects the
requested radio station.

MOST (media orientated systems transport) technology uses a plastic optical fibre which forms a network connecting the audio
and multimedia system components. Each component in the ring is connected to the plastic optical fibre through a device
known as a FOT (fibre optical transceiver). Each FOT (fibre optical transceiver) has two optical connections; one connection is
sensitive to light and is the input, the second connection forms the light source and is the output. The system operates by
connecting the output from one FOT (fibre optical transceiver) to the input of another FOT (fibre optical transceiver).
The light signals are sent in one direction only and are formed in the following way:
Electrical signals are converted into an electrical current
The current then drives an LED (light emitting diode) in the FOT (fibre optical transceiver) to produce a high intensity
red light
The LED transmits the light through a fibre optic cable A photo diode in the FOT (fibre optical transceiver) at the opposite end of the fibre optic cable detects the light.
The following components may be connected to the MOST ring dependant on the vehicle equipment level:
IAM (integrated audio module)
Touch-screen
ICM (information control module)
DAB (digital audio broadcasting) radio receiver (Optional - Europe only)
Satellite radio digital receiver (Optional - NAS only)
Power amplifier (Not fitted to the Jaguar Sound System)
Portable audio module (Optional)
Telephone control module (Optional)
Navigation computer (Optional)
TV tuner (Optional)


NOTE: Do not view the red light directly

MOST is a synchronous network. A timing master supplies the clock information and all other devices on the network
synchronize their operation to this clock. The timing master for the MOST (media orientated systems transport) network on this
vehicle is the ICM (information control module). This unit also controls and manages the MOST (media orientated systems
transport) ring and the system components.

An Optical Bus tester is used in conjunction with the Jaguar diagnostic system to diagnose the MOST (media orientated
systems transport) system. The Optical Bus tester emits a visible, high intensity red light which can be connected into the ring
at any point to test the ring integrity. Disconnecting a MOST (media orientated systems transport) connector will reveal if the
high intensity red light is visible.

If a break occurs in the MOST (media orientated systems transport) ring fault codes are stored in the ICM (information control
module) which can be retrieved using the Jaguar diagnostic system equipment.

With reference to the audio system information and signal transfer the instrument cluster is the gateway between the high
and medium speed CAN bus communication protocols. The ICM (information control module) is the gateway between medium speed CAN and the MOST (media orientated systems transport) 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 (information control module) gateway. The ICM (information control module) calculates the volume adjustment
required. The corrected audio volume level signal is sent on the MOST (media orientated systems transport) network to the
IAM (integrated audio module) 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

1 Volume adjustment 2 Change pre-set radio stations or CD tracks 3 Select audio source 4 Audio mute control/JaguarVoice control Additional control of the audio system is available in the form of steering wheel mounted switches which are located on the
left hand side of the steering wheel. The four switches provide for volume adjustment, change pre-set radio stations or CD tracks, select audio source and finally audio mute control. The mute control is also used for JaguarVoice control.

The steering wheel audio control switches are hardwired through the clock spring to the ICM. The ICM processes the analogue
signals from the switches into digital signals. The digital signals are then passed from the ICM onto the MOST system to
control the requested audio functions.

AVC (automatic volume control) controls the audio volume in relation to vehicle speed. As vehicle speed increases the audio
level is adjusted to compensate for extra road and vehicle noise. There are three settings for AVC:

Low
Medium
High
Setting of the AVC level is made using the audio controls. The default setting is medium.

The vehicle speed signal is used to enable the ICM to calculate the volume adjustment required. The vehicle speed signal is
received over the CAN. The signal is an average of the four wheel speed sensor signals. Should an invalid speed signal be received the AVC will not alter the output volume.



INTEGRATED AUDIO MODULE Component Description



The IAM is located in the center console behind the ICP faceplate, and combines the radio tuner and CD player. The head unit controls which of the two sources is routed to the speakers. All tuner versions have AM/FM reception. Each audio system
features auto-store, with a press and hold function to store selected channels as pre-sets. The standard search facility finds
the nine strongest channels currently available, while search and manual tuning allow channels to be stored as above.

The Jaguar Sound System IAM uses an internal amplifier which directly drives the system speakers. The Jaguar 320W Premium
Sound System and Bowers & Wilkins 440W Surround Sound System differs from the Jaguar Sound System with the addition of
an external amplifier. Audio output signals from the IAM are sent on the MOST system to the external amplifier which drives
the system speakers.
