Navigation IV and Navigation Plus-D
The new Navigation System IV and Navigation
System Plus-D are equipped with the dynamic
routing system.
The following traffic hold-ups are taken into
account during route planning:
– closed roads
– tailbacks and
– slow-moving traffic.
The system’s sources of information are the
traffic information from the radio stations via
the Travel Message Channel and from the
telematics
®
(optional) via the telephone
connection.
Once it is switched on, the navigation system
takes account of the traffic messages within a
radius of approx. 50 km around the vehicle.
If the route planning is activated, any hold-
ups are taken into consideration.
New hold-ups which arise are immediately
accounted for in the routing and the driver is
re-routed.
Data transfer of the traffic data is by
– Travel Message Channel data from the
radio
– Telephone data from the telematics control
unit J526
to the navigation system via the data bus
information system.
