Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
The RDS feature is available for use only on FM stations
that broadcast RDS information. This system relies upon
receiving specific information from these stations and
only works when the information is available. While the
radio is tuned to an FM-RDS station, the station name or
call letters displays. In rare cases, a radio station could
broadcast incorrect information that causes the radio
features to work improperly. If this happens, contact
the radio station.
