- Volume
- Bass
- Treble
- Balance
- Fader
- Equalizer
The Integrated Audio Module (IAM) compensates the sound amplitude depending on the vehicle speed and has automatic loudness.
If the vehicle is equipped with a Parking assistance module (PAM) a request is sent to the Integrated audio module (IAM), when audio is to be sent from the speakers than an object is close to the vehicle.
For further information, see Design and Function, Parking assistance module (PAM).
If the vehicle is equipped with a Multimedia module (MMM) the voice guidance (navigation) will be played over the vehicle's speakers.
The analog microphone signals are sent with telephone calls via the handsfree to the Integrated audio module (IAM). The signals are then sent via the MOST network to the Bluetooth phone module (BPM).
Speaker sound is sent from the Bluetooth phone module (BPM) to the Integrated audio module (IAM) via the MOST network.
Integrated Audio Module (IAM) handles playing of compressed music format for CD-disc (does not apply to Performance).
Support available for following formats:

Volume (reduce-increase) and selection of pre-programmed radio stations can be operated via remote control. During CD or USB/iPod playback, the buttons work as track selection.
The Steering wheel module (SWM) communicates via the CAN network with the Infotainment control module (ICM), which transmits the signals on to the Integrated Audio Module (IAM) via the MOST network.

Audio remote control (option)
