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 RDS is not implemented properly by the FM Broadcaster.

In some cases, a radio station broadcasting incorrect information may cause the RDS features of the radio to appear to work improperly.

Broadcast RDS information can be used in a variety of ways by the receiver and listener, but basically falls into two categories: Display and Control.
