What is RDS?
RDS station following
Tr a ffi c information function
Your radio automatically checks
and selects the best frequency
for the radio station to which it is
tuned (if the station broadcasts on se-
veral transmitters or frequencies).
The frequency of a radio station covers ap-
proximately 30 miles (50 km). The change
from one frequency to another explains
the loss of reception during a journey.
If the station to which you are listening
does not have several frequencies in
the region in which you are currently
located, you can deactivate the auto-
matic frequency following.
Radio, RDS, AF, REG, TP, PTY
Radio Data System (RDS) function
on the FM waveband permits:
- tuning to the same station while
travelling through different regions
(if the transmitters of this station
cover the area through which you
are travelling),
- temporary tuning to traffi c information
announcements,
- display of the name of the station,
etc...
Most FM stations use RDS.
These stations transmit non-audible
data in addition to their programmes.
The data transmitted in this way allows
you access to various functions, mainly
displaying of the name of the station,
temporary tuning to traffi c information
announcements or automatic station
following.
RDS allows you to continue listening to
the same station by means of the fre-
quency following. However, in certain
conditions, this RDS frequency follo-
wing cannot be provided throughout
the country. Radio stations do not cover
the whole country, which explains the
loss of reception of the station during
a journey. The Traffic Program (TP) func-
tion permits automatic and
temporary switching to an FM
station broadcasting traffi c information.
The radio station or the source that you
are listening to at this point is paused.
Once the traffi c information has ended,
the system switches back to the radio
station or the source that you were lis-
tening to initially.
Regional following mode
Some stations are organised in
a network.
In different regions, they broad-
cast different or shared programmes de-
pending on the time of day.
You can follow:
- a regional station only,
- the entire network, with the possibility
that you will be listening to a different
programme.

gramme as a priority, selected from
