Requirements for dynamic route guidance
TMC
(Traffic Message Channel)
is
a digital radio
data service for the
constant
transmission of
traffic reports.
The unit
is
constantly supplied with
TMC
traffic
messages
in
the background when a
TMC
trans-
mitter can be received at the current location.
The quality
ofthe
traffic messages sent
depends
on the radio station broadcasting
it.
The recep-
tion ofTMC traffic messages
cannot
be switched
on or off.
The transmitter must not be the
TMC
trans-
mitter.
TMC
traffic messages can only be evaluated
by
the device and displayed
when
the navigation
data for the currently driven area
is
stored in the
unit memory or can be called up using an in-
serted navigation
DVD.
The current
TMC
traffic messages can be dis-
played by pressing the
[TRAFFIC)
function selec-
tion button
=>
page 107.

Note
• If there are serious traffic problems, you may
find that a diversion based
on
the
TMC
informa-
tion does not save you time as the alternative
route
is
also subject
to
traffic problems.
•
You
can also block the route manually if an
upcoming traffic problem has not yet been
re-
corded via
TMC
traffic messages
