Radio Data System. RDS is a service provided by radio stations. In addition to conventional music and speech programmes, the stations also transmit additional information in the form of encoded digital signals that can be analysed by the car radio. The following RDS services are currently available. AF (Alternate Frequency): The car radio automatically selects the frequency with the best reception for the current programme.
EON: In the event that a traffic announcement (TA) is transmitted on any station in the station network, the car radio will automatically switch to that station for the duration of the message if you are currently listening to a station that does not transmit traffic information (i.e. from NDR 3 to NDR 2). Music/Speech (M/S): In future, a number of radio stations will differentiate between music and speech programmes. It is possible (with DSC) to select a separate setting (bass and treble cuts) for speech programmes.
PI code: With the help of the PI code, the car radio can identify the station you have tuned into. PS (Program Service): makes it possible to display the radio station name. PTY (Program Type): a function supported to an increasing extent by the radio stations that enables the car radio to select radio stations by their programming (i.e. news, rock, pop, sport, etc.). RT (Radiotext): additional information transmitted by the radio station on the current programming (i.e. the title of the programme, the name of the musical artist, etc.).
