Important notes COMAND Online calculates the route to the
destination without taking account of the fol-
lowing, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rules and regulations
COMAND Online may give differing driving
recommendations if the data on the digital
map does not correspond to the actual con-
ditions, such as if the road layout has
changed.
For this reason, you must always observe
road and traffic rules and regulations during
your journey. Road and traffic rules and reg-
ulations always have priority over system
driving recommendations.
Route guidance begins once a route has been
calculated (Y page 329).
COMAND Online guides you to your destina-
tion by means of navigation commands in the
form of audible navigation announcements
and route guidance displays.
The route guidance displays can be seen if the
display is switched to navigation mode.
If you do not follow the navigation announce- ments or if you leave the calculated route,
COMAND Online automatically calculates a
new route to the destination.
If the digital map contains the corresponding
information, the following applies:

Recording the route Notes
If you have activated COMAND Online and the
SD memory card has been inserted, you
should not take it out of the slot.
You can store up to 100 routes.
When you record a route, COMAND Online
uses so-called support points and displays
the route as a series of lines. If the route is
then calculated, COMAND Online attempts to
align the recorded route with the digital map.
The support points of the route may not be on
a digitised road. This is often the case with routes which are
drawn up using other map data and imported
via the online function, e.g.:
R routes from the Google™ Local Search
(Y page 442)
R routes from the destination/route down-
load (Y page 446)
