all major highways, service roads,
and residential roads. The detailed
areas include points of interest
(POIs) such as restaurants, airports,
banks, hospitals, police stations,
gas stations, tourist attractions, and
historical monuments. The map
database may not include data for
newly constructed areas or map
database corrections that are
completed after production of the
system. The navigation system
provides full route guidance in the
detailed map areas.

symbols that appear on a map
display.
The vehicle symbol indicates the
current position and heading
direction of the vehicle on the map.
The destination symbol marks the
final destination after a route has
been planned.
The waypoint symbol marks one or
more set waypoints.
A waypoint is a stopover destination
point added to the planned route.
The estimated time and distance to
the destination are displayed.If waypoints have been added to the
current route, each waypoint
destination displays estimated time
and distance.
This symbol indicates that the map
view is North up: North up displays

.State the destination and
request it to be downloaded to
the navigation system.
. The destination will then show in
detail on the Destination Entry
display where Start Guidance,
Show On Map, Save, etc., can
be used.
Global Positioning
System (GPS)
The position of the vehicle is
determined by using satellite
signals, various vehicle signals, and
map data.
At times, other interference such as
the satellite condition, road
configuration, condition of the
vehicle, and/or other circumstances
can affect the navigation system's
ability to determine the accurate
position of the vehicle.
The GPS shows the current position
of the vehicle using signals sent by
the GPS satellites. When the
vehicle is not receiving signals from the satellites, a symbol appears on
the map display. See
Navigation
Symbols 039.
This system might not be available
or interference can occur if any of
the following are true:
. Signals are obstructed by tall
buildings, trees, large trucks,
or a tunnel.
. Satellites are being repaired or
improved.
For more information if the GPS is
not functioning properly, see
Problems with Route Guidance 050
and
If the System Needs Service 050.
Vehicle Positioning
At times, the position of the vehicle
on the map could be inaccurate due
to one or more of the following
reasons:
.
The road system has changed.
. The vehicle is driving on slippery
road surfaces such as sand,
gravel, or snow. .
The vehicle is traveling on
winding roads or long straight
roads.
. The vehicle is approaching a tall
building or a large vehicle.
. The surface streets run parallel
to a freeway.
. The vehicle has been transferred
by a vehicle carrier or a ferry.
. The current position calibration
is set incorrectly.
. The vehicle is traveling at high
speed.
. The vehicle changes directions
more than once, or the vehicle is
turning on a turn table in a
parking lot.
. The vehicle is entering and/or
exiting a parking lot, garage, or a
lot with a roof.
. The GPS signal is not received.
. A roof carrier is installed on the
vehicle.
. Tire chains have been installed.
. The tires are replaced or worn.

.The tire pressure for the tires is
incorrect.
. This is the first navigation use
after the map data is updated.
. The 12-volt battery has been
disconnected for several days.
. The vehicle is driving in heavy
traffic at low speeds, and the
vehicle is stopped and started
repeatedly.
Problems with Route
Guidance
Inappropriate route guidance can
occur under one or more of the
following conditions:
.The turn was not made on the
road indicated.
. Route guidance might not be
available when using automatic
rerouting for the next right or
left turn.
. The route might not be changed
when using automatic rerouting.
. There is no route guidance when
turning at an intersection. .
Plural names of places might be
announced occasionally.
. It could take a long time to
operate automatic rerouting
during high-speed driving.
. Automatic rerouting might
display a route returning to the
set waypoint if heading for a
destination without passing
through a set waypoint.
. The route prohibits the entry of a
vehicle due to a regulation by
time or season or any other
regulation that may be given.
. Some routes might not be
searched.
. The route to the destination
might not be shown if there are
new roads, if roads have
recently changed, or if certain
roads are not listed in the map
data. See Maps038.
To recalibrate the vehicle's position
on the map, park with the vehicle
running for two to five minutes, until
the vehicle position updates.
If the System Needs
Service
If the navigation system needs
service and the steps listed here
have been followed but there are
still problems, 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. The map data is updated
periodically, provided that the map
information has changed.
For questions about the operation of
the navigation system or the update
process, contact the GM Nav Disc
Center toll-free phone number,
1-877-NAV-DISC (1-877-628-3472)
or go to the center's website,
www.gmnavdisc.com. If updates are
needed, call the GM Nav Disc
Center. To order map data, have the
vehicle's Vehicle Identification
Number (VIN) available. See
“Vehicle Identification Number
(VIN)” in the owner ’s manual.

52 Voice Recognition
Voice Recognition
Voice recognition allows for
hands-free operation within the
audio and phone applications. This
feature can be started by pressing
b/gon the steering wheel or
touching the voice recognition icon
on the touchscreen 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
selecting 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 pressing one or two
options, and are not supported by
voice commands.
Most voice commands, except for
voice keypad, can be completed in
a single command. If the task takes more than one command to
complete, the first command would
be to indicate the kind of task to be
performed. The system will reply,
prompting dialog to help speak the
necessary information.
Voice recognition can be used when
the ignition is on or when Retained
Accessory Power (RAP) is active.
See
“Retained Accessory Power
(RAP)” in the owner ’s manual.
Using Voice Recognition
Voice recognition becomes available
once the system has been
initialized. Initialization takes place
once the ignition is turned on. This
may take a few moments.
1. Press
b/gon the steering
wheel controls to activate voice
recognition, or touch the voice
recognition icon on the
infotainment display.
2. The audio system mutes and the system plays a prompt
followed by a beep. 3. Wait until after the beep
completes, then clearly speak
one of the commands
described in this section.
Press
b/gto interrupt any
voice recognition. This will
terminate the prompt. The beep
is heard immediately, and a
command can be stated
without having to wait.
There are two voice prompt modes
supported:
. Long verbal prompts: The longer
prompts provide more
information regarding the
supported actions for that voice
recognition session.
. Short prompts: The short
prompts provide simple setup
and action commands.
The voice prompt modes can be
changed in the Voice Recognition
Menu from the Settings icon on the
Home Page.
If a command is not heard during a
short period of time, the voice
recognition process times out.
