>>> NAVIGATION MODE
Taking announcements into
consideration when calculating routes
Your Navigation device can take traffic
announcements into consideration when
calculating a route. You have the option
of setting this function to automatic,
manual or never in the menu in the
navigation settings with the TMC option
(see "The TMC or Traffic button
(model dependent)" on page 77).
Automatic recalculation
If the traffic on your route is obstructed,
the Navigation device checks whether an
expedient detour of the obstruction is
possible. If an expedient detour is
possible, then an alternative route is
calculated and you are guided via the
alternative route.
Manual recalculation
If a traffic announcement affects your
route, a window with detailed informa-
tion on the traffic announcement ap-
pears.
If, after displaying the traffic message,
the navigation system detects that a
sensible alternative route is possible, the
following display appears.
The display provides you with an
overview of the alternative route
calculated.
The red route or route marked blue for
an obstruction shows the previous route.
The route marked yellow displays the
alternative route calculated.
In the right section of the display, you can
see how much the route changes and
how much time you will likely save if you
use the alternative route.
> Now either press the
OK button to use
the alternative route or press the
Reject button to continue using the
existing route.
Note:
This display may also appear if, for
example, a previously obstructed route
is now free again.
