The task of the Accessory USB unit (AUU) is to manage playback of media that is stored on the external USB memory and the iPod player.

The Accessory USB unit (AUU) supports media formats:

The accessory USB unit (AUU) (4/124) is controlled via the buttons on the center console. Signals indicate when the user has pressed the Play or Stop button.

The accessory USB unit (AUU) communicates with the infotainment control module (ICM) (16/94) via the MOST network. The infotainment control module (ICM) then uses the MOST network to send the signals on to the integrated audio module (IAM) (16/1) or the audio module (AUD) (16/105) depending on vehicle configuration.

The accessory USB unit (AUU) has functions for:

next track/previous track
fast forward/rewind
random playback (Random)
system search (scan)

Any stored text information is also sent via the MOST network to the infotainment control module (ICM) display, where it is displayed.
