• 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.

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.
