07 RADIO
ACTIVATE/DEACTIVATE RDS
RDS, if displayed, allows you to continue listening to the same
station by automatic retuning to alternative frequencies. However,
in certain conditions, coverage of an RDS station may not be
assured throughout the entire country as radio stations do not
cover 100 % of the territory. This explains the loss of reception
of the station during a journey.
