System overview

Media player module (MPM)





The media player module (MPM) players play back MiniDiscs and CDs. There are three versions of the media player module (MPM):
- CD player
- CD changer
- combined CD/MD player.

Only one media player module (MPM) can be installed in the car.

The media player module (MPM) is located in the center console.

The media player module (MPM) uses optical serial communication to communicate with other components on the MOST network. This means that all communication with the media player module (MPM) is via the infotainment control module (ICM). The media player module (MPM) communicates with the audio module (AUD) for access to the loudspeakers.

Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using VIDA via the data link connector (DLC) in the car.

Signals

The table below summarizes the input signals to and output signals from the media player (MPM). These signals type are only transmitted via MOST communication. The illustration below displays the same information with the Volvo component designations.

Input signals Output signals
Via MOST communication: Via MOST communication:
- Infotainment control - Audio module (AUD) (16/105)
module (ICM) (16/1). - Infotainment control module (ICM) (16/1).





Design

Media player module (MPM)





There are three versions of the media player module (MPM):
- CD player
- CD changer
- combined CD/MD player.

The magazine for the CD changer is integrated in the control module.

The media player module (MPM) is controlled using the buttons on the center console. The buttons for volume control and for selecting the CD track or radio station are also on the steering wheel.
The actual status is shown on the display for the infotainment control module ICM).

All input and output signals from the control module are transmitted on the MOST network

Function

Playing discs





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.
