AF – Alternative frequency
The range of FM stations is limited. For this
reason, FM programmes are distributed to
different frequencies. The AF RDS service
sends these frequencies to the tuner. If the
reception deteriorates because the vehicle
leaves the reception area of a frequency,
the tuner can automatically change to the
best receivable frequency.

RDS – Radio Data System
RDS is a service of the radio stations.
