RDS, if activated, 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.
