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 considerably supplemented by voice outputs with the following instructions:

• Route summary (following route calculation, a route summary is output)
• Warning at freeway approach roads
• Turning recommendations
• Junction names
• Corners
• Railroad crossings

The voice output of the navigation system can be performed in the two 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 in area with restricted traffic access
• Route via ferry
• Route via toll road

Function sequence 

The voice data is stored on the hard drive of the COMAND operating, display and controller unit as individual word segments. The navigation processor of the COMAND operating, display and controller unit links word segments during voice output to form complete instructions or information and generates speech signals. The voice output signals are forwarded via the Media Oriented System Transport (MOST) to the amplifier for sound system (N40/3), with code (810) Sound system, where they are amplified and output over the following speakers via direct lines:

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

In vehicles without code (810) Sound system, the voice output signals are amplified in the COMAND operating, display and controller unit and output via direct lines over the following speakers:

• Left front door speaker
• Right front door speaker

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

• Using the rotary actuator on the COMAND operating, display and controller unit
• With the + and -, for setting specific functions and volume control (S111s1) in the right multifunction steering wheel button group (S111)
