Cadillac 2008 CTS - Manual (Page 219)

Your vehicle may have one of these radios as its audio
system.
If your vehicle does not have one of these radio
systems, it may have a navigation radio system. See
the Navigation System manual for more information on
the navigation audio system.
If your vehicle has one of these radios, it has either a
Bose
® sound system or a Bose ® 5.1 Cabin Surround ®
sound system. See “Digital Signal Processing (DSP)”
later in this section for more information on the
Bose
® 5.1 Cabin Surround ® sound system.
The radio with DVD Audio, HDD, and USB utilizes
Gracenote
® technology to provide Song, Artist, Album,
and Genre information for many CD audio discs
and is capable of playing DVD-A and DTS encoded
discs, (DTS and DTS Digital Surround are registered
trademarks of Digital Theater Systems, Inc.).

Radio Data System (RDS)
The audio system has a Radio Data System (RDS)
feature. RDS 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 display. 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.
