The steering wheel remote control (standard/option) is directly connected to the steering wheel module (SWM) via serial communication. The remote control can be used to change volume (increase/decrease) and change the preset radio stations. During CD, cassette or MD playback, the buttons are used for track selection. The steering wheel module (SWM) uses the CAN network to communicate with the infotainment control module (ICM), which then sends the signals on to the integrated audio module (IAM) via the MOST network.
