equipped with mbrace and a valid
subscriber account: each destination
address can be downloaded by each
vehicle. This requires each vehicle to be
registered with an e-mail address in your
mbrace account. Route guidance
Important notes COMAND calculates the route to the
destination without taking account of the
following, for example:
R
traffic lights
R stop and give way signs
R merging lanes
R parking or stopping in a no parking/no
stopping zone
R other road and traffic rules and regulations
R narrow bridges
COMAND may give differing navigation
commands if the actual street/traffic
situation does not correspond with the digital
map's data. For example, if the road layout or
the direction of a one-way street has been
changed.
For this reason, you must always observe
road and traffic rules and regulations during
your journey. Road and traffic rules and
regulations always have priority over the
system's driving recommendations.
Route guidance begins once a route has been
calculated (Y page 331). Navigation

Recording the route Notes
If you have activated COMAND and the SD
memory card has been inserted, you should
not take it out of the slot.
When you record a route, COMAND uses so-
called support points and displays the route
as a series of lines. If the route is then
calculated, COMAND attempts to align the
recorded route with the digital map.
The support points of the route may not be on
a digitized road.
This is often the case for routes that have
been calculated using map data from other
sources. Calling up the Routes menu
