Voice control function sequence
The control signal of the VCS [SBS] switch is forwarded to the COMAND operating, display and controller unit via the following components:
- Steering column tube module (N80)
- Instrument cluster (A1)
- Controller area network bus, class B (interior compartment) (CAN B)

Voice input takes place via the VCS [SBS] microphone, which is connected to the COMAND operating, display and controller unit by a direct line. The spoken word is converted to an electrical signal by the VCS [SBS] microphone and transferred to the COMAND operating, display and controller unit. Voice output takes place directly (without code 810 Sound system) or via the sound system amplifier (N40/3) (with code 810 Sound system) via the following speakers:

- Left front door speaker group (H4/1)
- Right front door speaker group (H4/2)
- Center cockpit speaker (centerfill) (H4/27)
