The media player module (MPM) players play back MiniDiscs and CDs.

The media player module (MPM) (16/107) receives input signals from the infotainment control module (ICM) (16/1) via the MOST network. The signals indicate when the user has pressed the Play, Stop or Eject buttons for example.

The media player module (MPM) has functions for:

• next/previous track
• fast search forwards and backwards
• random play
• scanning
• ejecting the disc.

The CD changer also has a function for selecting the desired disc.

When playing back a disc, the media player module (MPM) transmits signals via the MOST network to the audio module (AUD) (16/105). The audio module (AUD) then transmits the signals on to the loudspeakers.

Any text information stored on the MD or CD is also transmitted via the MOST network and then shown on the display on the infotainment control module (ICM). This function does not however apply to CDs player in the CD player, only to discs played in the CD changer and MD player.
