MODEL 164.8, 251.0/1 with CODE (527) COMAND APS with single DVD drive (with navigation) with CODE (498) Japan version as of model year 2009/Modification Year 2008 

Function requirements 

• Status c. 15R ON
• Cockpit Management and Data System (COMAND) active and operating error-free
• No fault in handsfree system microphone group (A67b1)

General information 

The voice control system (VCS [SBS]) can be used to call up and operate the individual functions in the driver information system and telephony. The VCS is integrated into the COMAND operating, display and controller unit (A40/3). Voice control can be performed by spelling or saying entire words over the handsfree system microphone group.

Operating instructions 

The VCS [SBS] is activated or deactivated via the following buttons on the multifunction steering wheel (MFL):

• VCS on button (S111s4)
• VCS off button (S110s4)

A signal tone sounds after the VCS [SBS] has been activated.

As of 1.7.09, when the voice control is active, the blower output of the blower motor (A32m1) will be reduced to max. 50 % to avoid any misinterpretation during voice input. Regulation is carried out using the AAC [KLA] control and operating unit (N22) (without code (581) Comfort automatic air conditioning) or the comfort AAC [KLA] control and operating unit (N22/7) (with code (581) Comfort automatic air conditioning).

Voice control function sequence 

The control signal from the VCS [SBS] on button and the VCS [SBS] off button is transferred to the COMAND operating, display and controller unit via the following path:

• Steering LIN (LIN E1)
• Steering column tube module (N80)
• Engine compartment CAN (CAN C)
• Instrument cluster (A1)
• Interior CAN (CAN B)

Voice input is made via the accompanying handsfree system microphone group. The words spoken are converted into an electrical signal by the handsfree system microphone group and routed to the COMAND operating, display and controller unit via direct lines.

On vehicles with code (810) Sound system, voice output is performed by means of audio signals by the COMAND operating, display and controller unit via the Media Oriented System Transport (MOST) to the amplifier for sound system (N40/3) and from there, via direct lines, to the following speakers:

• Left front door speaker (H4/5)
• Right front door speaker (H4/6)

In vehicles without code (810) Sound system, voice output is sent by the COMAND operating, display and controller unit using audio signals via direct lines to the following speakers:

• Left front door speaker
• Right front door speaker
