Important notes
WarningG
For safety reasons, you should only enter a
destination when the vehicle is stationary.
When the vehicle is in motion, a passenger
should enter the destination. Study manual
and select route before driving.
Do not watch display screen or operate but-
tons while the vehicle is in motion - let voice
instructions guide you. Stop at a safe loca-
tion before using buttons or making correc-
tions.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just
30 m.p.h. (approximately 50 km/h), your
car is covering a distance of 44 feet (approx-
imately 14 m) every second.
The route calculated by COMAND is a rec-
ommendation on how to best reach your se-
lected destination.
During route guidance, you will not receive
any information on
Traffic lights
Stop and yield signs
Parking or stopping zones
One-way streets
Narrow bridges
Similar traffic regulation data
You should therefore always strictly observe
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs even if they contradict COMAND in-
structions.
WarningG
The Navigation DVD module contains a
Class 1 laser product. There is a danger of
invisible laser radiation if the cover is
opened or damaged.
Do not remove the cover. The Navigation
DVD module does not contain any parts ser-
viceable by the user. For safety reasons,
have any necessary service work performed
by qualified personnel.
The display unit can cause injury if contac-
ted when open. Return the display unit after
inserting a Navigation DVD to its closed po-
sition (
page 204).

Route guidance
Route guidance in these areas
When you are
entering a partially digitized area
or
starting route guidance within such an
area,
the navigation system will inform you that
turn by turn guidance cannot be provided
with corresponding navigation displays
and voice announcements.Map display
Within these areas the display shows a
split screen with the map on the left-hand
side and a direction arrow on the right side
pointing to the destination instead of the
symbol for the next driving maneuver
(page 174).
Route presentation
Usually the map highlights the active route
on verified roads with a blue line.
After route calculation, the route may
contain unverified road sections. Here, the
exact route guidance is suppressed and
these route sections will appear as blue
dotted lines. This type of line e.g. connects
two verified road sections, which are
displayed as blue lines or connects the end
of a verified road with a stopover or
destination located on an unverified road.
i
Displayed or audible distance to the
beginning of such an area is an
estimation. The actual distance may
differ.
WarningG
If the origin and destination are located very
close to each other, the system may not pro-
vide the shortest path to the destination
when you are travelling in an unverified area.
In most cases you will be directed to a veri-
fied road closest to the destination. This
may appear to be a long and inconvenient
route but it is safer. At your own risk, you
may choose to drive on the unverified roads
to the destination.
