Navigation
In certain circumstances, avoiding conges-
tion due to a TMC traffic report may not save
time if, for example, the detoured section is
already saturated with traffic. The quality of
the dynamic route guidance depends on the
information contained in the TMC traffic re-
ports. The radio stations broadcasting this in-
formation are responsible for the content.
The route to cover can also be blocked man-
ually to force a new route to be calculated

In guided navigation, traffic incidents that af-
fect the calculated route are displayed in red,
while those that do not are displayed in grey.
The length of a traffic incident along the
route calculated is represented by a red line.
The TMC symbol is located at the start of the
traffic delay, provided it has been defined
clearly in the TMC traffic report.
Depending on the scale of the map, other
congestion icons may be hidden behind one
TMC icon. In this case, press the TMC icon
and a list will open with further traffic inci-
dents present.

, Demo mode
is active ›››
page 37 , an additional pop-up

starts.
● Pressing the function button Demo mode starts a “virtual” guided navigation to the fi-
nal destination indicated.●
If you press the function button
Normal mode , the “real” guided navigation
will begin.
The sequence of events and the operations in
virtual route guidance are similar to those in
real route guidance.
Virtual route guidance is repeated when you
reach the fictitious destination and always
starts again from the starting point if it is in-
terrupted.
If in the menu Navigation setup the starting
point of the Demo mode was determined
manually, the virtual guided navigation will
begin from this position.
A starting point introduced manually is over-
written with the current location of the vehi-
cle, if the vehicle starts to move and if the ve-
hicle's location can be determined by the
GPS.
When real route guidance is started following
virtual route guidance in demo mode, the
unit first has to reorient itself. This orienta-
tion can last some time depending on the
number of satellites that are received at that
time. Moving the vehicle may speed up the
reorientation process. Note
Deactivate the Demo mode after use, because
otherwise before starting guided navigation 36
