- Instrument cluster
- Interior CAN
A signal tone is emitted after the voice control system has been activated.
The signal tone in vehicles with code (810) Sound system, is transmitted by the "audio unit" via Media Oriented System Transport (MOST) to the amplifier for sound system (N40/3). From there, the signal tone is transmitted over direct lines to the following speakers:
- Left rear door speaker (H4/3)
- Right rear door speaker (H4/4)
- Left front door speaker (H4/5)
- Right front door speaker (H4/6)
- Center cockpit speaker (centerfill) (H4/27)

- Right front door tweeter (H4/34)
- Left rear door tweeter (H4/35)
- Right rear door tweeter (H4/36)
- Left rear surround speaker (H4/54)
- Right rear surround speaker (H4/57)
The audio signal for the subwoofer speaker (H4/29) travels over MOST from the "Audio equipment" to the sound system amplifier and from there, over the subwoofer amplifier (N40/9), via direct lines, to the subwoofer speaker.
In vehicles except code (810) Sound system, the signal tone is transmitted directly from the "audio unit" via direct lines to the following speakers:
- Left rear door speaker
- Right rear door speaker
- Left front door speaker
- Right front door speaker
- Left front door tweeter
- Right front door tweeter
- Left rear door tweeter

- "Dial number"
- "Redial"
- "Listen to telephone book"
- "Listen to or delete address book"
- "Open or spell entries"
- "Landline or mobile"
- "Dial"
The voice commands are acquired by the hands-free system microphone group (A67b1) and forwarded to the "audio equipment" via a direct line.
The voice control of the voice control system (VCS) is used to establish the telephone call in the hands-free mode.
Function sequence, establish call for phone call in hands-free mode
When the call has been established successfully, the "audio unit" transmits or receives the mobile phone signals or data in the following way:

- Direct line
- Telephone/cell phone/STH radio remote control antenna splitter (A2/53), with code (228) Stationary heater, and direct line
- Telephone antenna (A2/93a3)
The voice input in hands-free mode is registered by the hands-free system microphone group and forwarded via a direct line to the "audio equipment".
The voice output in vehicles with code (810) Sound system, is conducted by the "audio unit" to the sound system amplifier control unit via MOST. From there, the voice output is transmitted via direct lines to the following speakers:
- Left rear door speaker
- Right rear door speaker
- Left front door speaker
- Right front door speaker
- Center cockpit speaker (centerfill)
- Left front door tweeter
- Right front door tweeter
- Left rear door tweeter
- Right rear door tweeter

In vehicles except code (810) Sound system, the signal tone is transmitted directly from the "audio unit" via direct lines to the following speakers:
- Left rear door speaker
- Right rear door speaker
- Left front door speaker
- Right front door speaker
- Left front door tweeter
- Right front door tweeter
- Left rear door tweeter
