allows you:

you are travelling through different regions
(on condition that the transmitters for this
station cover the area being travelled
through),
to listen to traffi c announcement fl ashes
on a temporary basis
to have the station name displayed, etc.

The majority of FM stations use the
RDS system.
These stations process non-audio data
in addition to their programmes.
The data broadcast in this way gives
you access to a variety of functions
that are described in this chapter,
notably the display of the station name,
temporary traffi c information fl ashes
and automatic station search.
It allows to listen to the same sta-
tion thanks to the frequency search.
But RDS frequency search is not
guaranteed over the whole country.
The radio stations cannot cover the
entire territory, which explains the
loss of reception of the station during
a journey.
Your NaviDrive automatically checks and
selects the best frequency for the radio sta-
tion captured (provided the station transmits
on more than one frequency).
The frequency of a radio station extends
to around 50 km. Loss of reception during
a journey is explained by the change from
one frequency to another.
If the station you have selected does not
broadcast on different frequencies in the
areas in which you are travelling, it is possible
to deactivate the automatic RDS transmission
scanning function.
The display will indicate:
RDS while the function is activated
and available.
RDS shaded while the function is
activated but not available for the
station being listened to.

Certain stations are organised in a net-
work.
In the various regions, they transmit pro-
grammes that are sometimes different,
sometimes common.
You can do a search:
On a regional station only
On the entire network, with the possibility
of hearing a different programme.
•
•
When the function is activated: your
NaviDrive does not change from one
regional station to another.
When the function is deactivated:
your NaviDrive selects the best fre-
quency from among the regional
stations.
