Route guidance
Usually COMAND guides you through fully
digitized areas on verified roads for as long
as possible. Route guidance is conducted
in the usual manner, i.e. with navigation
announcements and route guidance dis-
plays, map or split screen.
The DVD map may contain areas that are
only partially digitized with unverified
roads although they are within a digitized
region.Verified roads
include information about the road’s
average speed, turning restrictions, or
whether it is a one-way street
are typically roads within a
metropolitan area, interstate freeways
or major roads connecting cities
enable reasonably accurate route
calculation and selection
Unverified roads
are roads which lack the expected
road’s average speed and other
attributes
could be smaller city streets and roads
either named incorrectly, have no
name or the name is shown in the
wrong location
may not enable reasonably accurate
route calculation and selection
Partially digitized areas/unverified
roadsWarningG
Due to incomplete digitization, the route
shown on the map may differ from the actual
road/traffic situation.
If you follow the route shown on the map, for
example, it is possible that you could drive
the wrong way down a one-way street, that
a street cannot be driven on or that the road
is of questionable quality.
When using route guidance on a unverified
road in a partially digitized area, you must
therefore be sure to observe all relevant
traffic regulations and the course of the
road.
Drive carefully and keep in mind that all rel-
evant traffic regulations and the course of
the road always take priority over the route
shown on the map.

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.

Display examples are shown below:

the blue dotted line will disappear and a
red dotted line will appear. The line is your
dynamic reference, it moves with the
current vehicle location.

currently travelling on a unverified road
to guide you back to a verified road
or
to guide you to a stopover or
destination located on a unverified
road too.
If the vehicle reaches a verified road again,
the red dotted line will disappear and route
guidance will simply continue in the usual
manner.
i
Stopover and destination are located
on unverified roads:
The map highlights the route section
between a stopover and a destination
with a blue dotted line first. After the
vehicle reaches the stopover, then the
red dotted line will appear.

WarningG
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of traversing through without
damaging your tires, wheels or vehicle. It is
the driver's sole responsibility to determine
the suitability of the route. Off-road routes
may be of varying conditions and their ap-
propriateness for use may be affected by
various factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into consider-
ation by the COMAND system.
i
An OFF ROAD destination is not itself
recorded on the map. You can enter an
OFF ROAD destination using the map,
for example (
