The command“Play Album”must first
be spoken; the system will then ask
for the album name. The reply would
be to say the name of the album
to play.
Once the number of files has exceeded
approximately 24,000, there is no
support for accessing the songs
directly through voice commands.
There will still be access to the media
content by using commands for
playlists, artists, and genres.
The access commands for playlists,
artists, and genres are prohibited after
the number of this type of media
exceeds 12,000.
The system will provide feedback the
first time voice recognition is initiated
if it has become apparent that any of
these limits are reached during a
device initializing process.
Voice recognition performance will
degrade to some extent based on
many factors when adding large
amounts of data to recognize. If this is
the case, perhaps accessing songs
through playlists or artist name would
work better.Voice Recognition for

Bluetooth (Overview)
The Bluetooth-capable system can
interact with many mobile devices,

hands-free mode.
.Sharing of the device’s address book
or contact list with the vehicle.
To minimize driver distraction, before
driving, and with the vehicle parked:
.Become familiar with the features of
the mobile device. Organize the
phone book and contact lists clearly
and delete duplicate or rarely used
entries. If possible, program speed
dial or other shortcuts.
.Review the controls and operation
of the infotainment system.
.Pair mobile device(s) to the vehicle.
The system may not work with all
mobile devices. See “Pairing”later in

use a Bluetooth-capable mobile device
with a Hands-Free Profile to make and
receive phone calls. The infotainment
system and voice recognition are used
to control the system. The system can
be used while the ignition is on or in
ACC/ACCESSORY. The range of the
Bluetooth system can be up to 9.1 m
(30 ft). Not all mobile devices support
all functions and not all mobile
devices work with the Bluetooth
system. See my.cadillac.com for more
