62 Navigation
With dynamic guidance, the whole of
the current traffic situation that is
received by the Infotainment system
via RDS TMC is incorporated into the
calculation of the route.
If there is a traffic hold-up (e.g. traffic
jam, road closure) on the planned
route, you will be informed of this by
the Infotainment system and you can
decide whether the system should
avoid the problem by changing the
route in order to avoid the segment
concerned or whether it would be
more sensible just to drive through
the problematic road section.
This enables the system to check
continuously during guidance on the
basis of the traffic information
whether there is a better route for
route guidance and a new route is
sometimes calculated, for example, if
a traffic jam has disappeared.
■ Dynamic guidance can be
activated/deactivated in the
navigation Settings menu 3 38.
■ The basis for the possible delay
due to a traffic hold-up and
calculated by the Infotainment
system is data that the system
receives via the currently selected
RDS TMC station. From
experience, the actual delay may
deviate from the calculation.
■ The dynamic guidance only works
if the Infotainment system receives
traffic information via RDS TMC.
TMC reception is indicated by the
TMC symbol in the main display of
the Audio function.
Depending on the traffic situation,
there are two different types of detour:
1. Extensive detour
As soon as the Infotainment system
has received information about one or
more traffic hold-ups via RDS TMC
that would mean a relatively long
delay for navigation to your
destination, the system offers you
well in advance of the hold-up the
option of taking a detour around the
traffic hold-ups.
If a relatively long delay on your route
is expected due to traffic hold-ups,
a message informing you of the
calculated delay is given.
■ Select Recalculate if you want to
make an extensive detour around
the traffic hold-ups.
■ Select Cancel if you do not want to
make a detour.
Even after cancelling, it is possible to
have the route recalculated via the
Detour menu item.
Traffic hold-ups that are expected to
result in just a short delay are
detoured locally if desired via the
Detour function (see below).
In the immediate vicinity of a traffic
hold-up, a warning is issued again
and a detour of the immediate traffic
holdup (local detour) is offered via the
Detour menu item.
2. Local Detour
