To recalibrate the vehicle's position on
the map, park with the vehicle
running for two to five minutes, until
the vehicle position updates. Make
sure the vehicle is parked in a location
that is safe and has a clear view of the
sky and away from large obstructions.
If the System Needs
Service
If the navigation system needs service,
see your dealer.
Map Data Updates
The map data in the vehicle is the
most up-to-date information available
when the vehicle was produced.
See www.gmnavdisc.com for details on
ordering, purchasing, and installing a
new or replacement SD card. Features
are subject to change. For more
information on this feature, see
my.cadillac.com/learn.
Database Coverage
Explanations
Coverage areas vary with respect to
the level of map detail available for
any given area. Some areas feature
greater levels of detail than others.
If this happens, it does not mean
there is a problem with the system. As
the map data is updated, more detail
can become available for areas that
previously had limited detail. SeeMap
Data Updates 0163.
Voice Recognition
If equipped, voice recognition allows
for hands-free operation within the
navigation, audio, phone, and weather
applications. This feature can be
started by pressing
gon the steering
wheel or touching
gon the
infotainment display.
However, not all features within these
areas are supported by voice
commands. Generally, only complex
tasks that require multiple manual
interactions to complete are
supported by voice commands. For example, tasks that take more
than one or two touches, such as a
song or artist to play from a media
device, would be supported by voice
commands. Other tasks, like adjusting
the volume or seeking up or down, are
audio features that are easily
performed by touching one or two
options, and are not supported by
voice commands.
In general there are flexible ways to
speak commands for completing the
tasks.
If your language supports it, try
stating a one-shot command, such as
“Directions to address city, state/province>.”
Do not include
the ZIP code while stating the address
during the command. Another
example of a one-shot Destination
Entry command is, “Directions to
Place of Interest at .” If these
commands do not work, try saying,
“Take me to Place of Interest ”or “Find
address ”and the system will walk you
through by asking additional
questions.

Hybrid Speech Recognition
If equipped, this feature helps
distinguish words by using
Internet-based information along with
the system’s voice recognition
database. This allows you to speak
more naturally when using voice
recognition.
Using Voice Recognition
Voice recognition becomes available
once the system has been initialized.
This begins when the ignition is
turned on. Initialization may take a
few moments.1. Press
gon the steering wheel
controls to activate voice
recognition.
2. The audio system mutes and the system plays a prompt.
3. Clearly speak one of the commands described in this section.
A voice recognition system prompt
can be interrupted while it is
playing by pressing
gagain.
Once voice recognition is started, both
the infotainment display and
instrument cluster show the selections and visual dialog content. These
displays can be turned on or off in the
Tutorial Mode under
Settings0176.
There are three voice prompt modes
supported:
.Informative verbal prompts: This
type of prompt will provide more
information regarding the supported
actions.
.Short prompts: This type of prompt
will provide simple instructions
about what can be stated.
.Auto informative prompts: This type
of prompt plays during the first few
speech sessions, then automatically
switches to the short prompt after
some experience has been gained
through using the system.
If a command is not spoken, the voice
recognition system says a help
prompt.
Prompts and Infotainment Displays
While a voice recognition session is
active, there may be corresponding
options showing on the displays.
A selection can be made by manually
touching the option, or by speaking
the number for the option to select. Manual interaction in the voice
recognition session is permitted.
Interaction during a voice session may
be completed entirely using voice
commands while some manual
commands may expedite a task. If a
selection is made using a manual
control, the voice recognition dialog
will progress in the same way as if the
selection were made using a voice
command. Once the system completes
the task, or the session is terminated,
the voice recognition dialog stops.
An example of this type of manual
intervention is touching an entry of a
displayed number list instead of
speaking the number associated with
the entry desired.
Canceling Voice Recognition
.Touch or say
“Cancel”or“Exit ”to
terminate the voice recognition
session and show the display where
voice recognition was initiated.
.Pression the steering wheel
controls to terminate the voice
recognition session and show the
display where voice recognition was
initiated.
