Route guidance begins when route
calculation is complete.
The system will calculate a new route
during active route guidance if the driver
does not follow the route guidance.
NEW RTE is displayed during recalculation.
The arrow is not filled out.After route calculation, the system assists

Voice instructions
WarningG
Voice instructions are intended to direct you
while driving without diverting your attenti-
on from the road and driving.
Always use this feature instead of consulting
the map display for directions. Consulting
the map displays for directions may cause
you to divert your attention from driving and
increase the risk of an accident.

Route guidance
If the destination is within a partially
digitized area
COMAND guides you through fully digitized
areas for as long as possible. Route
guidance is conducted in the usual
manner, i.e. with navigation announce-
ments and route guidance displays.
Before the vehicle reaches a partially
digitized area, COMAND notifies you of
this with the following announcements:
“Be prepared to enter an area where
turn by turn guidance cannot be
provided.”
“In 700 feet you will enter an area
where turn by turn guidance cannot be
provided.”
Partially digitized areas
i
The digital map may contain areas that
are only partially digitized although
they are within a digitized region.
WarningG
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 re-
levant traffic regulations and the course of
the road always take priority over the route
shown on the map.
i
The indicated distance can be seen
here by way of example. In reality, it
may be different.

“You are about to enter an area where
turn by turn guidance cannot be
provided.”
Route guidance within a partially
digitized area
If you start route guidance in this type of
area, you will hear the following
announcements:
“You are currently in an area where
turn by turn guidance cannot be
provided.”
“Please follow the arrow on the
display.”Route guidance is provided by means of a
direction arrow showing the compass
heading to the destination. COMAND will
not generate automatic navigation
announcements.
If you try to repeat the current voice
instruction manually, (
page 151) you will
hear the announcement “You are currently
in an area where turn by turn guidance
cannot be provided.”.
During route guidance, the display is
divided. On the right-hand side you will see
the direction arrow showing the compass
heading to the destination.
On the left-hand side of the display you will
see the map with the suggested route. The
suggested route is highlighted blue.
However, it may not be possible to follow
the suggested route because, for example,
the road is closed or not open for car
traffic.1Current vehicle location and direction

If, during route guidance, COMAND leads
you back into a fully digitalized area, route
guidance will simply continue in the usual
manner.

When you call up the route info to this
type of destination, (

following data shown there may differ

157 Navigation
Route guidance
Route guidance to an off-road destina-
tionCOMAND can guide you to destinations
within the area covered by the digital map,
even if a destination is not located at a
road known to the system.
These destinations are shown as off-road
destinations, which you can enter using
the map, for example.
In these cases, COMAND guides you for as
long as possible with navigation announce-
ments and displays on roads known to the
system.
Shortly before you reach the last known
point in the digitized road network, you will
hear the announcement “The destination
is nearby. Follow the arrow on the display”.
You will then see an arrow that indicates
the direction to the off-road destination.
When the off-road destination is close to
the road, “Area of dest. reached” appears
in addition below the arrow.The section of the route from the last
known point on the map to the off-road
destination is highlighted blue. It simply
shows the direction to the off-road
destination without taking into account
any type of obstacles in the way.

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 va-
rious factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into considerati-
on by the COMAND system.

158 Navigation
Route guidance
On the off-road section of the route, direc-
tion arrows showing the compass heading
to the destination guide you. You will also
see the “Direction to destination” display.
Route guidance from an off-road
location to a destination
If there is no road available on map at cur-
rent position of the car, vehicle is off road.
COMAND is also able to guide you to a des-
tination from such a location.
At the start of the route guidance, you will
see the “Off Road” message and a direc-
tion arrow. The direction arrow shows the
compass heading to the actual destina-
tion.
The route is highlighted blue from the
nearest road known to the system.
As soon as the vehicle is back on a road
known to the system, route guidance con-
tinues in the usual way.Route guidance from an off-map
location to a destination
If the vehicle position is outside the area
covered by the digital map, then the vehi-
cle is in an off-map location.
COMAND is also able to guide you to a des-
tination from such a location.
At the start of the route guidance, you will
see the “Off Map” message and a direction
arrow. The direction arrow shows the com-
pass heading to the actual destination.
The route is highlighted blue from the near-
est road known to the system.
As soon as the vehicle is back on a road
known to the system, route guidance con-
tinues in the usual way.Off-road during route guidance
The road layout may differ from the data on
the digital map, due to road construction
measures, for example.
In such cases, the system cannot allocate
the vehicle’s position to the digital map
and the vehicle is therefore in an off-road
position.
The “Off Road” message and an arrow
showing the compass heading to the
destination appear on the display.
As soon as the system can allocate the
vehicle position’s to the map again, route
guidance continues in the usual way.
