Control unit for voice control system (VCS [SBS])
Card reader for SD memory card
Operating elements
The status of the buttons on the operating panel of the COMAND controller unit are read in and made available to the arithmetic unit. The button operations undergo further processing in the arithmetic unit and are forwarded via the MOST, the telematics CAN (CAN A) or the interior CAN (CAN B) to the other system components in the form of messages. If the ON button on the COMAND controller unit is pressed, the COMAND controller unit is switched on. The volume is regulated for each audio source set by turning the ON button. The function buttons switch over to the audio source desired by the user.
In the event of system fault or system crash, pressing the "ON" button for t = 8 s will reboot the COMAND controller unit.
DVD drive
With the aid of the integrated DVD drive, audio CDs/DVDs or video DVDs can be played and data (e.g. updates) from the navigation DVD can be stored on the internal hard disk.
Navigation and GPS control unit
The navigation processor is integrated into the COMAND controller unit and calculates the location of the vehicle using the incoming antenna signals. It also calculates the vehicle's route after the destination has been entered.
Gyro sensor
The gyro sensor determines vehicle direction changes. It is installed into the navigation processor. Calibration is not required.
Control unit for voice control system (VCS [SBS])
The voice commands are processed and evaluated in the COMAND controller unit. The voice outputs for the dialog with the user are generated in the COMAND controller unit.
Card reader for SD memory card
With the aid of the integrated card reader, data and audio files from an SD memory card can be stored on the hard disk (except CODE 528 (COMAND incl. DVD changer)) and subsequently retrieved again.
On vehicles as of 1.6.13 the card reader can also read SDXC cards. To save data from the COMAND controller unit onto the SD card, a Personal Identification Number (PIN) protection can be activated. If PIN protection is activated then the specified PIN has to be entered first before any data can be saved onto the SD card.
Variants
The COMAND controller unit is available in the following variants:
With CODE 527 (COMAND APS with single DVD drive (with navigation))
With CODE 512 (COMAND APS with DVD changer)
With CODE 528 (COMAND with DVD changer)
Diagnosis
The COMAND controller unit is the diagnosis gateway for all MOST users. The diagnostic communication takes place between the COMAND controller unit and the front SAM control unit with fuse and relay module (N10/1) via the interior CAN. The diagnostic communication between the front SAM control unit with fuse and relay module and the diagnostic connector (X11/4) connected to the ISE tester takes place via the diagnostic CAN (CAN D).
