Radio with CD
Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected type of
programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
Seek to stations with traffic announcementsThis system relies upon receiving specic information
from these stations and will only work when the
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.
While the radio is tuned to an RDS station, the station
