Mexico-13690484) - 2021 - crc - 8/17/20
Infotainment System 175
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 are installed on the vehicle.
.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
where driving is 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 which 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. SeeMaps
0 167.
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. The map data is

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-13690484) - 2021 - crc - 8/17/20
176 Infotainment System
updated periodically, provided that the map
information has changed and the vehicle has
a relevant service plan.
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.chevrolet.com/learn.
If the vehicle is equipped with Connected
Navigation, which is a subscription service
that enables certain features of the
navigation system, such as Traffic, Smart
Search/Routing, and Predictive Navigation,
then the system will download the latest
map data from the cloud.
Database Coverage Explanations
If equipped, 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 0175.
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 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.

Mexico-13690484) - 2021 - crc - 8/17/20
Infotainment System 177
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 underSettings
0 187.
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. 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.”

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-13690484) - 2021 - crc - 8/17/20
178 Infotainment System
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.
Manually scrolling or paging the list on a
display during a voice recognition session
suspends the current voice recognition event
and plays the prompt “Please select
manually or touch the Back icon on the
infotainment display to try again.”
If manual selection takes more than
15 seconds, the session terminates and
prompts that it has timed out. The display
returns to the display where voice
recognition was initiated. The Back Command
Say
“Back” or touch the Back icon on the
infotainment display to go to the
previous menu.
If in voice recognition, and “Back”is spoken
all the way back to the starting display, and
then “Back” is spoken one more time, the
voice recognition session will cancel.
Help
Say “Help” on any voice recognition display
and the help prompt for the display is
played.
Voice Recognition for the Radio
If browsing the audio sources when voice is
touched, the voice recognition commands
for AM, FM, and SiriusXM (if equipped) are
available.
“Switch to AM” :Switch bands to AM and
tune to the last AM radio station.
“Switch to FM” :Switch bands to FM and
tune to the last FM radio station.
“Switch to SXM” :Switch bands to SiriusXM
and tune to the last SiriusXM channel.
“Tune to AM” :Tune to
the radio station whose frequency is
identified in the command (like “nine fifty”).

“Voice Keypad” :Begin a dialog to enter
special numbers like international numbers.
The numbers can be entered in groups of
digits with each group of digits being
repeated back by the system. If the group
of digits is not correct, the command
“Delete” will remove the last group of digits
and allow them to be re-entered. Once the
entire number has been entered, the
command “Call”will start dialing the
number.Phone Assistant Voice Recognition
Press and holdgon the steering wheel
controls to pass through and launch Google
