OVERVIEW
The audio system contains the following functions:
CD player
AM/FM tuner
Digital Audio Broadcast (DAB)/SDARS radio systems (where available)
HD radio system (where available).
The audio system is available in 2 versions, Standard and Premium.
The Standard audio system uses an internal amplifier which directly drives the system speakers and contains a single disc
Compact Disc (CD) player. The Standard audio system is controlled purely from the head unit and the remote steering
wheel controls. The head unit is connected to the vehicle on the medium speed Controller Area Network (CAN) bus. This
allows the unit to be interrogated for diagnostic purposes.
The Premium audio system comprises the following components:
Integrated Audio Module (IAM)
Infotainment Control Module (ICM)
Separate audio amplifier
Rear seat audio control modules with head phone sockets
Surround sound speaker system
Control of the Premium audio system is via the ICM located in the center of the instrument panel. Control signals from the
ICM are sent to the rest of the audio system on the Media Orientated System Transport (MOST) ring. The ICM is the timing
master for the MOST ring and also hosts a gateway function between the medium speed CAN bus and the MOST ring.
Audio signals are sent on the MOST ring from the Integrated Audio Module to the amplifier.
