Control module




The integrated audio module (IAM) is mounted in the center console. It is integrated with the audio unit and they are replaced together.
The infotainment control module (ICM) display shows the current status of the integrated audio module (IAM).
The Integrated Audio Module (IAM) has an integrated amplifier (only Performance) with an output of 4x20 W.
The two other versions do not have an integrated amplifier, they use the Audio module (AUD) as an amplifier.

Antennas

C30/S40/V50





C70




Integrated Audio Module (IAM) is connected to an antenna system for AM and FM. This consists of two FM-antennas (FM1 and FM2) and an antenna for AM.
For C30 and C70, FM1 is also used as AM-antenna.
Antennas are connected to one or two antenna boosters depending on vehicle model.
Integrated Audio Module (IAM) has two channels, one for FM1 and AM as well as one for FM2.
Both channels are connected to the integrated audio module (IAM) via a coaxial cable.
Connection for the FM2-antenna (sub-antenna) is used for voltage feed of the antenna booster.

Remote control




Remote control via a steering wheel keypad is available as either an option or as standard equipment depending on the market. The keypad is located on the right side of the steering wheel and is connected to the steering wheel module (SWM) via serial communication.

Loudspeakers




The integrated audio module (IAM) for Performance has 4 speakers directly connected to the control module:
- one pair of front loudspeakers
- one pair of rear loudspeakers.
Impedance for each speaker is 4 ohms.
For the two other versions with the integrated audio module(IAM), the speakers are connected to the audio module (AUD).
