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 primarily supported by voice outputs with the following information:
- Direction information
- Name of road onto which the next turnoff should be made

The voice output of the navigation system features the following languages:
- German
- English (UK and USA)
- French
- Spanish
- Italian
- Dutch
- Danish
- Swedish
- Portuguese
- Turkish
- Russian
- Chinese (traditional or simplified)

Additional voice messages take place at the start of the route calculation, when an intermediate destination is reached, or when the destination is reached.

Operating instructions
The radio with auto pilot system (A2/56) is operated using the following components:
- Using the buttons on the radio with auto pilot system
- Using the Audio/COMAND control panel (A40/9)
- Using the left multifunction steering wheel button group (S110) and the right multifunction steering wheel button group (S111)

Function sequence
The radio with auto pilot system combines, through the integrated navigation processor, the word segments into complete instructions or information during a voice output and generates low frequency (LF) signals. The LF signals are forwarded, if necessary, via Media Oriented System Transport (MOST) to the sound system amplifier control unit (N40/3) (with code (810) Sound system), where they are amplified and output via direct 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 without code (810) Sound system, the LF signals are amplified in the radio with auto pilot system and output via direct lines to 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 switch on the radio with auto pilot system
- Using the + and - buttons for setting specific functions and volume control (S111s1)

The volume of the audio outputs is adapted dynamically to the noise level in the vehicle interior. This is done through the speed-dependent volume control (SDV [GAL]).

A special note is given during voice output in the following cases:
- Destination in area not accessible by car
- Destination in area with restricted traffic access
- Route via ferry
- Route via toll road
