Radio, Stereo, and Compact Disc: Description and Operation
Audio System
COMPONENT LOCATION
INTRODUCTION
The audio system contains the following functions:
- Six disc CD autochanger.
- AM/FM tuner.
- Interface Protocol Option Devices (iPod) and USB connectivity (from 2009 MY).
The audio system is available in two versions, standard and premium. The standard audio system uses an internal amplifier to drive the system speakers. The premium system uses an external amplifier and subwoofer assembly to drive the speakers. For additional information, refer to Speakers Description and Operation
Control of the audio system is via the integrated control panel and the TSD, located in the center of the instrument panel, and the remote audio switches on the steering wheel.
Control signals from the integrated control panel are relayed on the medium speed CAN (controller area network) bus to the information and entertainment module. The information and entertainment module relays the control signals to the rest of the audio system on the Media Orientated System Transport (MOST) ring. The information and entertainment module is the timing master for the MOST ring and also hosts a gateway function between the medium speed CAN (controller area network) bus and the MOST ring. On premium audio systems the audio signals are sent on the MOST ring from the integrated audio module to the amplifier. The control signal from the remote audio switches to the information and entertainment module consists of an analogue voltage from a resistive ladder.
The iPod and USB connectivity allows audio files on portable media players and mass storage devices (i.e. portable audio devices) to be played through the speakers of the audio system. The audio system supports portable audio devices with a storage capacity up to 256 GB (approximately 65,000 music tracks).
The iPod and USB connectivity is provided by:
- -- An auxiliary input panel, installed in the cubby box of the floor console.
- -- An auxiliary USB unit, attached to the RH rear quarter panel, behind the trim of the luggage compartment.
The auxiliary input panel provides the interface between the portable audio device and the vehicle's audio system. An iPod port and a USB port are located in the top of the auxiliary input panel, underneath a protective rubber cover. An iPod connector lead is supplied with the vehicle. Portable audio devices can be connected to both ports at the same time.
The iPod and USB ports both incorporate a charging function. The maximum charging current supplied is 500 ma.

The auxiliary USB unit translates the electronic signals from the auxiliary input panel into optical signals and transmits them on the MOST ring.
Operation of the portable audio device is controlled from the TSD via the integrated audio module. For road safety reasons, the normal control interface of the portable device is disabled when it is plugged into the auxiliary input panel, and it can only be controlled from the TSD.
Portable Audio Device Selection on TSD
Some MP3 players have a file system that is not supported by the audio system. To use one of these MP3 players with the audio system, the MP3 player must be set to USB Removable Device mode or Mass Storage Device mode (see the MP3 player manufacturer's information for further details). Only files that have been added to the MP3 player in these modes can be played on the audio system.
A number of other vehicle systems are operated from the TSD and the integrated control panel, or have inputs into the audio system. These include:
- Air conditioning system. For additional information, refer to Air Conditioning Air Conditioning
- Navigation. For additional information, refer to Navigation System Description and Operation
- Parking aid. For additional information, refer to Parking Aid
- Telephone. For additional information, refer to Cellular Phone Description and Operation
Software in the information and entertainment module generates the graphics for the TSD.
