146 Infotainment System
Handling Large Amounts of Media Content
It is expected that large amounts of media
content will be brought into the vehicle.
It may be necessary to handle large
amounts of media content in a different
way than smaller amounts of media. The
system may limit the options of voice
recognition by not allowing selection of files
by voice at the highest level if the number
of files exceeds the maximum limit.
Changes to voice commands due to media
content limits are:
.Files including other individual files of all
media types such as songs, audiobook
chapters, podcast episodes, and videos.
.Album type folders including types such
as albums and audiobooks.
There are no restrictions if the number of
files and albums is fewer than 12,000. When
the number of files connected to the system
is between 12,000 and 24,000, the content
cannot be accessed directly with one
command like “Play
The restriction is that the command “Play
Song” must be spoken first; the system will
then ask for the song name. The reply
command would be to say the name of the
song to play. Similar limits exist for album content.
If there are more than 12,000 albums, but
fewer than 24,000, the content cannot be
accessed directly with one command like,
“Play
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.

period of time without an ignition cycle. To
find out the duration of time that applies
for the vehicle, contact an OnStar Advisor by
pressing
Qor calling 1-888-4ONSTAR. If the
vehicle has not been started for an extended
period of time, OnStar can contact Roadside

Global Positioning System (GPS)
.Obstruction of the GPS can occur in a
large city with tall buildings; in parking
garages; around airports; in tunnels and
underpasses; or in an area with very
dense trees. If GPS signals are not
available, the OnStar system should still operate to call OnStar. However, OnStar
could have difficulty identifying the exact
location.
.In emergency situations, OnStar can use
the last stored GPS location to send to
emergency responders.
A temporary loss of GPS can cause loss of
the ability to send a Turn-by-Turn
Navigation route. The Advisor may give a
verbal route or may ask for a call back after
the vehicle is driven into an open area.
Cellular and GPS Antennas
Cellular reception is required for OnStar to
send remote signals to the vehicle. Do not
place items over or near the antenna to
prevent blocking cellular and GPS signal
reception.

cellular network has reached maximum
capacity, this message may come on. Press
Qto try the call again or try again after
driving a few miles into another
cellular area.
