Audio systems are offered in two versions: Standard and Premium.
The Standard audio system uses an internal amplifier directly connected to the speakers and a single-disc CD player. The Standard audio system is controlled only by the head unit and by the remote controls located on the steering wheel. The head unit is connected to the car via a medium-speed CAN bus. This makes it possible to establish communication with the unit for diagnostics.
The Premium audio system includes the following elements:
- Integrated Audio Module (IAM)
- Infotainment Control Module (ICM)
- Separate audio amplifier
- Rear Seat Audio Control Modules with Headphone Jacks
- Surround Sound Speaker System
The Premium audio system is controlled via the ICM module, located in the center of the instrument panel. Control signals from the ICM are transmitted to other elements of the audio system via the MOST bus. The ICM module controls the MOST ring circuit schedule and also acts as a gateway between the medium-speed CAN bus and the MOST ring circuit. Audio signals are sent via the MOST ring circuit from the integrated audio module to the amplifier.
