Function requirements 

Route guidance by means of voice output, general 

The route guidance through voice output function in a language selected by the user is an assistant function, that aids the driver without distracting his attention from the traffic situation. The navigation system's route guidance is supported by voice output providing directions.

Additional voice messages are output at the start of the route calculation, when an intermediate stop is reached or when the destination is reached.

For vehicles without code (494) USA version, with dynamic route guidance additional voice messages are issued in response to routes influenced by traffic messages.

The COMAND control unit (A40/3) is operated through the following components:

The control signals from the front central operating unit are transmitted to the COMAND controller unit via the central CAN (CAN F).

The control signals of the multifunction steering wheel button groups are provided over the following route:

Function sequence for route guidance through voice outputs 

The COMAND controller unit links the information of the internal navigation processor with word segments to form complete instructions and information, and generates appropriate audio signals. These are forwarded over the Media Oriented System Transport (MOST) to the audio tuner control unit (N93/1) or the digital sound processor (A2/69) (model 221 as of 1.9.10 with code (811) Advanced Sound System), where they are amplified and emitted at the following speakers.

IMPORTANT During an active voice output the volume of the announcement can be adjusted by the following components:
