The voice data is originally stored on the navigation DVD as individual word segments. This data record is automatically transmitted from the DVD to the navigation processor (with hard disk) in the COMAND operating, display and controller unit, where it is stored.

If required, the voice output signals are forwarded over the Media Oriented System Transport (MOST) to the sound system amplifier (N40/3) (with code 810 Sound system), amplified and output on the following speakers via direct lines:

- Left front door speaker group (H4/1)

- Right front door speaker group (H4/2)

- Center cockpit speaker (centerfill) (H4/27)

In vehicles except code 810 Sound system, signals are amplified in the COMAND operating, display and controller unit and output at the speakers via direct lines:

- Using the volume control on the COMAND operating, display and controller unit

- With the + and , for setting specific functions and volume control (S111s1) in the right multifunction steering wheel button group (S111)
