Using the control system, the display
unit can be changed between km or
miles (see your vehicle’s Operator’s
Manual).
When the instrument cluster
multifunction display is set to miles,
the COMAND will indicate
distances in miles (mi) or feet (ft)
When the instrument cluster
multifunction display is set to
kilometers, the COMAND will
indicate distances in kilometers
(km) or meters (m)

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 180).
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 unconvenient
route but it is safer. At your own risk, you
may choose to drive on the unverified roads
to the destination.

Route guidance
Display examples are shown below:
1Road section known to the system
2Route section between the end of a
verified road and the destination on an
unverified roadIf the vehicle approaches a stopover or a
destination located on a unverified road,
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.

4Arrow indicates the direction of the
destination, the distance to destination
and
OFF ROAD indicationThis type of line will also appear if you are
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.
