GF82.85-P-3001RJ Voice Output, Function
- with CODE (498) Japan version


The navigation of the navigation system (based on DVD data basis) is basically supported by voice outputs:
^ Direction information
^ Name of the next road to turn into

The voice data are originally stored on the navigation Digital Versatile Disk (DVD) as individual word segments. This data record is automatically transferred by the DVD to the navigation processor of the COMAND operating, display and control unit (A40/3) and stored there. The COMAND operating, display and control unit (A40/3) supports both the Japanese and English languages.

Several driving recommendations in quick succession are combined into a single voice output.

This data for voice output is automatically transferred by the DVD to the navigation processor of the COMAND operating, display and control unit (A40/3) and stored there. The integrated navigation processor links these word segments to form complete instructions or information and generates corresponding low frequency (LF) signals. The LF signals generated in this manner are forwarded if required over the Digital Data Bus (D2B) to the sound amplifier (A2/13) (model 230.467 with Code (810) Sound system), amplified there and output via the vehicle speakers. The vehicle speakers can be selected using the "System settings" menu.
Loading a language takes a few seconds and changes both the voice output and the menu texts on the display of the COMAND operating, display and control unit (A40/3). Voice loading takes place again automatically after a power disconnection.

While a language is being loaded by the DVD, severe vibrations (e.g. bad road conditions) should be avoided. Otherwise the voice output might be broken up. In such cases it is necessary to reload the language.

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

Volume of voice output
The voice output volume can be adjusted during voice output . A definable difference (can be modified in "Settings" menu) is maintained between the volume of the current audio source and the voice output volume .

Example of voice output
The volume is turned down during voice output. If the specified volume difference to the audio signal is not attained, the COMAND operating, display and control unit (A40/3) reduces the level of the audio signal until the specified volume difference is attained again.After voice output has taken place, the volume of the audio signal is increased to match that of the voice output. The volume of the voice output cannot be reduced to below a certain minimum level.

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). The mute feature applies only for the current voice output. When navigation voice output and an audio source (e.g. radio tuner) are active simultaneously, the navigation voice output is switched to mute when the mute button is pressed for the first time and the complete playback is switched to mute when the mute button is pressed a second time.
