Fig. 90: MCS Voice Output Block Diagram

The navigation system guidance feature is supported significantly by voice output .

The voice data was originally stored as single-word segments on the navigation CD-ROM . This data set is

transmitted automatically by the CD-ROM to the navigation processor and stored there.

The navigation processor interlinks these word segments to complete instructions or information and generates

corresponding AF signals. The generated AF signals are transmitted internally in the radio and navigation

module (A2/56) to the audio signal processing if required, amplified there and output via the vehicle

loudspeakers.

With the sound system (code 810) the voice signals are transmitted to the sound amplifier (A2/13) from the

audio signal processing via the digital data bus ( D2B ), amplified there, and then output via the vehicle

loudspeakers.

Several short, sequential drive recommendations are compiled to one single voice output.

Loading voice from CD-ROM

Only English is presently available for voice output on the radio and navigation module (A2/56) .

Volume of voice output

The voice output volume can be adjusted during voice output . This ensures that a defined interval is

maintained between the volume of the current audio source and voice output.

Example:

If the volume is reduced during voice output and the preceding volume interval to the audio signal is not

reached the radio and navigation module (A2/56)
