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)

reduces the level of the audio signal until the specified volume interval is reached again. The volume of the
audio signal is then again increased after completion of the voice output to the level present before the voice
output.
Moreover, the volume of the voice output cannot be reduced below a certain minimum level .
Voice output mute circuit
Navigation voice output can be muted by actuating the mute multifunction key. Muting remains active until the
mute multifunction key is pressed again.

A new request is selected in the basic screen " SVC ":
"Send New Request for Info Service "
or optionally:
"View Info Service of..."
allows a previous data record to be viewed.
Selection is possible with the knob/pushbutton on the radio and navigation module (A2/56) and confirmed by
pressing. If" Send New Request for Info Service " is selected, the radio and navigation module (A2/56)
transmits this request via the digital data bus ( D2B ) to the E-call control module (A35/8) and CTEL
transmitter/receiver (A35) . It transmits the request to the service provider via the present telephone network.
The request is processed on the Internet on the basis of the personal information profile and sent to the vehicle
via the telephone network.
A tone and the message:" New Info Received! " indicates reception to the user. The safety question:" Read
Later When Stopped? " with the decision " Yes " or "No " serves for traffic safety.
Selecting:" Yes " leads to a return to the previous menu such as radio, CD, navigation......
Selecting:" No " lists the news according to the personal interest profile.
The messages can be read in sequence. Pressing the knob/ pushbutton button on the radio and navigation
module (A2/56) jumps to the next news item. Turning the knob/pushbutton on the radio and navigation
module (A2/56) scrolls the news. With the" BACK " button on the radio and navigation module (A2/56) it is
always possible to jump back to the previous menu.
The information that is received can be read page by page. It is not possible to jump directly to a certain
page. The format can be changed by the operator.

System concept of information service:
The vehicle owner determines his own interest profile for service information such as world news or stock
exchange data. He transmits the desired information to the Mercedes Benz Customer Service. This profile is
indicated to the S ervice O peration Center (SOC ).
With the" SVC " button on the radio and navigation module (A2/56) it is possible to transmit an update
request for service information to the S ervice O perating C enter (SOC ).
In the S ervice O peration C enter (SOC ) this customer profile is used for selecting information. The desired
information is compiled by the information provider and transmitted to the vehicle via the S ervice O peration C
enter (SOC ).
The data transmitted is indicated on the display in the radio and navigation module (A2/56) .
