map detail available. Some areas
have greater map detail than others.
The navigation system works only

on the map disc. See

on how to obtain
updated map information.
Voice Recognition
The navigation system's voice
recognition allows for hands-free
operation of the navigation system,
audio system, and OnStar
®
features. The DVD map disc must
be installed in the navigation system
for voice recognition to work. See
“
Installing the DVD Map Disc
”
under
Maps on page 43
. 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 your vehicle's owner
manual for more information.
To use voice recognition:
1. Push and hold the SRCE
(source) steering wheel control
until you hear a beep. The audio
system, if on, will mute.
2. Clearly state one of the
commands listed on the
following pages.
Helpful Hints for Stating

that best works for you.
