What is RDS?
The RDS(Radio Data System) is a digital information system
developed by the EBU(European Broadcasting Union). Pick-a-
backed on normal FM broadcasts, RDS offers a variety of
information services and automatic retuning functions for RDS-
compatible car stereos.
In 1988 RDS became available in the United Kingdom, France,
West Germany, Ireland and Sweden. Test transmissions are being
conducted in many other European countries. It is expected that
RDS will be available in most western European countries in the
near future.

transmitted along with FM broadcasts. It does not work in
the MW(AM). The RDS function may not work properly in
