Using RDS

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 which

station may broadcast incorrect information that will
cause the radio features to work improperly. If this
happens, please contact the radio station.
