INFOTAINMENT SYSTEM 163
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.

Natural Language Commands
Most languages do not support
natural language commands in
sentence form. For those languages,
use direct commands like the
examples shown on the display.
Helpful Hints for Speaking
Commands
Voice recognition can understand
commands that are naturally stated in
sentence form or direct commands
that state the application and
the task.
For best results:
.Listen for the prompt before saying
a command or reply.
.Speak the command naturally, not
too fast, not too slow.
.Use direct commands without a lot
of extra words. For example,“Call
at work,” “Play ”followed by
the artist or song name, or “Tune”
followed by the radio station
number.
.Navigation destinations can be
made in a single command using
keywords. A few examples are:
“I want directions to an address,”
“I need to find a place of interest or
(POI),” or“Find contact.”
The system responds by requesting
more details. For other POIs, say the
name of a category like
“Restaurants,” “Shopping Malls,” or
“Hospitals.”
.Navigating to a destination outside
of the current country takes more
than one command. The first
command is to tell the system
where the navigation will take place,
such as an Address, Intersection,
POI, or Contact. If Address or
Intersection is selected, the second
command is to say, “Change
Country.” Once the system responds,
say the country before saying the
rest of the address and/or
intersection.
If POI is asked for, say “Change
Location,” then“Change Country.” Direct commands might be more
clearly understood by the system. An
example of a direct command would
be
“Call .” Examples of these
direct commands are displayed on
most of the screens while a voice
session is active. If “Phone”or “Phone
Commands,” is spoken, the system
understands that a phone call is
requested and will respond with
questions until enough details are
gathered to make a call.
If a cell phone number has been saved
with a name and a place, the direct
command should include both, for
example “Call at work.”
Using Voice Recognition for List
Options
When a list is displayed, a voice
prompt will ask to confirm or select
an option from that list.
When a display contains a list, there
may be options that are available but
not displayed. The list on a voice
recognition screen functions the same
as a list on other displays. Scrolling or
flinging can be used to help display
other entries from the list.
