The radio navigation system

MFD radio navigation system with dynamic
route guidance
The traffic data used by the system is based on
the RDS TMC service which is supported by radio
stations and soon to be available throughout
Europe. Use of a RDS-TMC control unit allows
the driver to freely select a radio station for data
reception. This means that TMC data and normal
radio are received with different receivers.
All traffic information available within a radius
of approx. 200 km is utilised. If the dynamisation
function is activated by traffic conditions, the
driver is informed of this by the announcement:
„The route is being recalculated on the basis of
traffic information!"
Traffic delays (road closures, traffic jams and
slow-moving traffic) are visualised in the map
and are displayed as text messages.
RNS High/D with tuner
A radio navigation system with dynamic route guidance is also available as two-colour display
(low-end). In this system the RDS-TMC tuner is integrated in the radio navigation system.
