Menu Control Of The Multimedia Module (Mmm)

The on-screen menu can be controlled using the buttons on the reverse of the steering wheel.

The buttons consists of:

• a Back button
• an Enter button
• a navigation button which is used to move the cursor up, down, left and right on the screen.

These commands are transmitted from the steering wheel module (SWM) (3/130) to the infotainment control module (ICM) (16/1) via the Controller area network (CAN). The infotainment control module (ICM) converts the electrical signal to an optical signal and sends it onwards to the multimedia module (MMM) (16/108) via the MOST network.

The remote control for the multimedia module (MMM) has the same functions as the steering wheel buttons. The remote control can be used to control the menus on the display screen. An infra-red signal is transmitted from the remote control to an infra-red receiver on the infotainment control module (ICM), which in turn sends the signal on to the multimedia module (MMM) on the MOST network.
