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. See Maps
0 166.
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.
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

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 0 175.
Infotainment System

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
steering wheel or touching
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 <number, street, city, state/
province>. Do not include the ZIP code
while stating the address during the
