Using RDS
Your audio system is equipped with a Radio Data System
(RDS). RDS is a system that receives data along with
the audio of the FM station you are currently tuned to.
You can use RDS to display program information and
to control your radio. With RDS, the radio can do
the following:

Seek only to stations with the types of programs
you want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS features are only available on FM stations that
broadcast RDS information. The RDS features of your
radio rely on receiving specific RDS information from
these stations. These features will only work when the
RDS information is available. In rare cases, a radio
station may broadcast incorrect information that will
cause the radio features to work improperly. If this
happens, contact the radio station.When you are tuned to an RDS station, the station
name will appear on the display, instead of the
frequency. Most RDS stations provide their station
name, the time of day and a Program Type (PTY) for
their current programming. Some stations also provide
the name of the current program.
