System Operation

In-car entertainment

The audio system is connected to the MS CAN network and uses an internal amplifier which directly drives the system speakers. It can only be operated via the head unit and the radio remote control. The head unit is connected to the vehicle on the medium speed CAN bus. This allows the unit to be interrogated for diagnostic purposes.

The automatic volume control (AVC) adjusts the audio volume depending on the driving speed. The audio device receives the necessary signals for the ABS (anti-lock brake system) wheel sensors from the instrument cluster on the MS-CAN. As vehicle speed increases the audio level is adjusted to compensate for extra road and vehicle noise.

Eight AVC settings are possible.

To choose the setting for automatic volume control, press the MENU button until the AVC display appears.

The required adjustment level is determined by the Infotainment control unit based on the driving speed signal. 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.

AVC is controlled by the audio amplifier.
