Off-road during route guidance
Due to roadworks, for example, there may be
differences between the data on the digital
map and the actual course of the road.
In such cases, the system will temporarily be
unable to locate the vehicle position on the
digital map and thus considers the vehicle to
be in an off-road position.
In the display, you will see the
Street
unknown message, an arrow and the distance
to the destination. The arrow shows the
compass heading to the last road you were
driving on.
As soon as the system can assign the vehicle
position to the map again, route guidance
continues in the usual way.
Route guidance on roads that are not
completely digitalized
COMAND attempts to avoid roads that have
not been completely digitalized. If the
vehicle's position or the destination is located
in an area that has not been completely
digitalized, then no active route guidance is
performed. Instead, the map shows a dashed
route along the roads and the target direction
is shown with an arrow. You hear the
announcement: "You will enter an area,
where turn-by-turn guidance can not be
provided. Please follow the arrow on the
display". Once these roads have been left,
regular route guidance is resumed.
Traffic reports
Prerequisite
i The SatRadio mode described below
requires optional satellite radio equipment
and a subscription to SIRIUS XM Satellite
Radio Traffic Message Service. Further
details on SatRadio are available in the
"SatRadio" section (
Y page 216).
COMAND can receive traffic reports via
SatRadio and incorporate them in the
navigation system. Traffic messages and map
symbols can then be shown in the COMAND
display.
COMAND uses high quality traffic data.
Nevertheless, there may be differences
between the traffic reports received and the
actual road and traffic conditions.
Switching traffic reports on/off
X To switch on: set the route type to
Dynamic Route 7 ( Y page 152).
X To switch off: select the Fast Route or
Short Route route type ( Y page 152).
i COMAND calculates a new route if you
change the route type setting with route
guidance active. If you change the route
type setting when route guidance is
inactive, COMAND uses the new setting for
the next route guidance.
Real-time traffic reports on the map
COMAND can show certain traffic incidents
on the map. The incidents are shown on the
map at a scale from 1/16 mi to 20 mi.
X Set the map scale ( Y page 182).
