88 Infotainment System
Ordering Map DVDs
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 or order a new disc online.
To order a disc, have the vehicle's
Vehicle Identification Number (VIN)
available. This helps the center
make sure that the correct and most
up-to-date DVD map disc for the
vehicle is received. See “Vehicle
Identification Number (VIN)” in the
Index of the vehicle owner manual
for more information.
After receiving the updated disc,
see Maps on page 55 for more
information.
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 which previously had limited
detail. See Ordering Map DVDs on
page 88 for more information.
Voice Recognition
The navigation system's voice
recognition allows for hands free
operation of the navigation system
and the audio system features.
Voice recognition only works if
the map database is installed in
the system.
If the radio is off, the only
commands would be Hands Free
and Help.
Navigation voice commands are not
available until the OK button has
been selected.
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 index of the vehicle's
owner manual for more information.
