Route guidance by means of voice output, general
The route guidance through voice output function is an assistance function that assists the driver without distracting him from the traffic.
The destination-oriented navigation of the navigation system is supported by voice outputs with the following information:
- Directional instructions
- Name of the next road to turn into
Additional voice messages are emitted at the start of the route calculation, when an intermediate stop is reached or when the destination is reached.
The voice output of the navigation system is performed in the selected system language.
The radio with auto pilot system (A2/56) is operated using the following components:
- Control buttons on the radio with auto pilot system
- Audio/COMAND control panel (A40/9)
- Left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111)
- Voice control system (VCS) (with code (511) Audio 50 APS incl. DVD changer)
The control signals of the left and right multifunction steering wheel button groups are provided via the following route:
- Steering wheel electronics (N135)
- Steering LIN (LIN E1)
- Steering column module control unit (N80)
- Chassis CAN (CAN E)
- Instrument cluster (A1)
- Interior CAN (CAN B)
- Radio with auto pilot system

Function sequence for route guidance through voice outputs
The radio with auto pilot system links the information of the internal navigation processor with word segments to form complete instructions and information, and generates appropriate audio signals.
The voice output in vehicles without code (810) Sound system takes place via the following speakers:
- Left door tweeter (H4/1h1)
- Left door bass speaker (H4/1h2)
- Right door tweeter (H4/2h1)
- Right door bass speaker (H4/2h2)
On vehicles with code (810) Sound system, the radio with auto-pilot system transmits the audio signals via the media-oriented system transport (MOST) to the sound system amplifier control unit (N40/3), which amplifies and output them over the following speakers:
- Door tweeter
- Door bass speaker
- Center dashboard speaker (H4/27)
The volume of the announcements can be adjusted using the following components:
- Volume controller on radio with auto pilot system
- Audio/COMAND control panel
- + and - button for setting specific functions and volume control (S111s1)
The volume of the audio output is controlled by means of speed- dependent volume control.
A special note is given during voice output in the following cases:
- Destination lies in area where driving is not possible
- Destination lies in area where driving is only possible to a limited extent
- Route via ferry
- Route via toll road
