Route guidance via voice output, function

"Voice output" function

The destination-oriented navigation of the navigation system is considerably supplemented by voice outputs with the following instructions:

 Directional instructions

 Name of the next road to turn into

The voice data originally stored on the navigation DVD as individual word segments, are automatically transmitted into the navigation processor (N41/1) where they are stored.

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

 English

 British English (ECE only)

 US English (USA only)

 French

-------------------------------------------------------------------------------------------

 Spanish

 Italian

 Dutch

 Danish

 Swedish

 Portuguese

 Turkish

 Several route recommendations in quick succession are combined to form a single voice output.

The navigation processor combines the word segments into full instructions or information and generates appropriate low-frequency (LF [NF]) signals.

-------------------------------------------------------------------------------------------

If necessary, the low frequency signals thus generated are forwarded via Media Oriented System Transport (MOST) to the COMAND operating, display and controller unit (A40/3) or to the audio gateway control unit (N93/1) where they are amplified and output via the vehicle speakers.

 Loading a language takes a few seconds and changes both the voice output and the menu texts on the LCD color display of the COMAND operating, display and controller unit. Voice loading takes place again automatically after a power disconnection.

 While a language is loaded from the navigation DVD, it is necessary to avoid severe physical shocks. Otherwise voice output may be given in fragments. In such an instance the language should be loaded again.

-----------------------------------------------------------------------------------------

Superimposition of voice output and an audio source.

When voice output is active simultaneously with an audio source (e.g. CD, radio tuner), the two signal sources are superimposed.

Volume of voice output

The voice output volume can be adjusted during voice output.
A defined interval (can be set in the "Settings" menu) is automatically maintained between the volume of the current audio source and the volume of the voice output.

Voice output mute circuit

The navigation voice output can be muted during voice output by pressing the mute button (button marked with struck-out speaker). Muting is only valid for the current voice output.

-----------------------------------------------------------------------------------------

When navigation voice output and an audio source (e.g. CD, radio tuner) can be heard simultaneously, the navigation voice output is muted when the mute button is pressed for the 1st time and the complete playback is muted when the mute button is pressed for the 2nd time.

Notes with voice output

Voice output takes place when the system recommends turns and when turning into a numbered street. A special note is given during voice output for certain areas:

These areas are:

 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

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