Radio with CD (Base)
If your vehicle has the Bose®audio system,
your vehicle has six Bose®amplied speakers.
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
This system relies upon receiving specic
information from these stations and only works
when the information is available. In rare cases,
a radio station can broadcast incorrect information
that causes the radio features to work improperly.
If this happens, contact the radio station.
While the radio is tuned to an RDS station, the
station name or call letters display instead of
the frequency. RDS stations can also provide the
time of day, a program type (PTY) for current
programming, and the name of the program
being broadcast.
