General 

The route guidance through voice output function is a comfort function that assists the driver during a journey without diverting his/her attention from the traffic. The destination-oriented navigation of the navigation system is primarily supported by voice outputs with the following information:

• Route summary (following route calculation, a route summary is issued)
• Warning at highway approach roads
• Turnoff recommendations
• Junction names
• Corners
• Railroad overpasses

The voice output of the navigation system features the following languages:

• Japanese
• English

The following messages are also issued during route guidance through voice output:

• Destination, intermediate destination or stopover reached
• Influence of route by traffic information
• Start of route calculation

In the following instances a special instruction is issued during voice output:

• Destination lies in area where driving is only possible to a limited extent
• Route via ferry
• Route via toll road

Function sequence 

The voice data is originally stored on the navigation DVD as individual word segments. This data record is automatically transmitted from the DVD into the navigation processor (with hard disk) of the COMAND controller unit where it is stored.

The voice output is forwarded, if necessary, over the Media Oriented System Transport (MOST) to the sound system amplifier control unit (N40/3) (with code (810) Sound system), where it is amplified and output over discrete lines to the following speakers:

• Left front door speaker (H4/1)
• Right front door speaker (H4/2)
• Center instrument panel speaker (H4/27)

In vehicles except code (810) Sound system, the voice output takes place on discrete lines via the COMAND control unit to the following speakers:

• Left front door speaker
• Right front door speaker
• Center instrument panel speaker

When voice output is active the announcement volume can be adjusted using the following components:

• The volume controller on the COMAND controller unit
• The buttons + and - for setting specific functions and volume control (S111s1) of the right multifunction steering wheel button group (S111)
