The CD/MP3 audio systems are equipped with technology known as the Radio Data System (RDS). The RDS is a system that sends data along with the audio of the FM station you are currently tuned to. The RDS is a standard that defines how a FM broadcast station may send digital data along with the audio program. Think of it as a one-way wireless modem, allowing the broadcaster to send information about the program to your receiver.
RDS Basic Information
- RDS functions are provided in the FM broadcast band only.
- RDS functions will only work with FM broadcast stations that are broadcasting RDS data.
- Not all FM Broadcast stations broadcast RDS data or offer all of the RDS services.
- RDS functions may not work properly when reception is weak, reception is of poor quality, or the FM Broadcaster does not implement RDS properly.
In some cases, a radio station broadcasting incorrect information may cause the RDS features of the radio to appear to work improperly.
