You can also start a route guidance in demo mode

purposes.
Navigation system voice guidance
Route calculation is announced with a voice message. During this time, the
display will show a list of the selected route criteria options (
and the dash panel display will show an arrow. This arrow faces in the direc-
tion of the entered destination.
When route calculation is complete, guidance is given by spoken driving
instructions and symbols. The spoken navigation directions are given in good
time before a turn-off.
You can use the following options to repeat the last navigation voice
message:
•
Press the rotary pushbutton while in the
Nav-Info
menu.
•
Press the control button for
Nav-Info
if you are
not
already in the
Nav-Info
menu.
•
press the right thumbwheel on the multi-function steering wheel*
If the navigation CD is inserted in the CD player
page 25, the language in
which the navigation system voice guidance is given can be changed
Caution
If driving instructions run contrary to traffic laws, the traffic laws always take
precedence.
Note
•
You can adjust the volume of the voice guidance prompts as they are
being announced using the on/off button
page 11 on the navigation
control console or the right thumbwheel on the multi-function steering
wheel*
•
If the vehicle is in a location that cannot be read by the navigation system
(e.g. car park or garage), a voice message will inform you of such. The arrow
in the dash panel display faces in the direction of the entered destination.
•
In neighbouring countries, the instructions given are slightly different to
those of your country of origin, as the navigation CD for these countries only
contains the main roads.
Dynamic navigation
The dynamic navigation function calculates routes based on
the currently available TMC traffic messages.
If the dynamic navigation function
page 103 is activated and a TMC radio
station is set, the system constantly checks whether relevant TMC messages
are available for the selected route. If the navigation system then determines
that a TMC traffic message is relevant for the current route, the system will
automatically calculate a new route plan to the destination.
The navigation system receives and processes the traffic announcements
issued by certain channels (TMC) in addition to regular programming. The
reception of TMC traffic messages is free of charge in Germany.
Note
•
Please note that the TMC messages sent by the radio stations may not
always be complete and correct.
