Infotainment System 145
Global Positioning System (GPS)
If equipped, 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 GPS satellites.
When the vehicle is not receiving signals
from the satellites, a symbol appears in the
status bar.
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 0145 and
If the System Needs Service 0146.
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.

146 Infotainment System
.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

0 137.
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 updated periodically, provided that the map
information has changed and the vehicle has
a relevant service plan.
Over-the-Air-Vehicle Map Updates
If equipped, the infotainment system can
receive map updates over the air. Map
updates occur within a 161 km (100 mi)
radius around the home address on file. This
boundary will adjust over time based on
driving patterns. The vehicle uses a
Cloud-connected service to receive the date
and downloads it to the system’s onboard
SD card, if equipped. A data plan or
compatible mobile device hotspot is
required. The SD card is required for
navigation system function.
When a map update is available, a prompt
will appear on the infotainment display.
Once the update is accepted, it will
download and run in the background
without interruption any infotainment
functions. The download will carry over
ignition cycles, stopping and starting where
it left off. The updates can be set to
download automatically.
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.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. See
Map Data
Updates 0146.
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

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
