Traveling Across Regions
If driving across several states, the selected region
might have to be changed to represent the destination.
There are two ways to plan a destination when
traveling across regions.
The following method is suggested and provides the
most route guidance and map display functions:
1. Change the selected search area region as you get
closer to the destination. See “Setting the Search
Area” underMaps on page 4-38.
2. Enter the destination and route settings. SeeEnter
Destination on page 4-27for more information.
If not using the rst method, keep the currently
selected search area region and enter the destination.
This method allows a destination selection from the
easy planning route method or from the All Points of
Interest (POI) categories with the “All Search Areas”
comment for US Only. For example, Tourist is a category
that features this comment. SeeEnter Destination on
page 4-27for more information.If traveling in or to Canada and the regional border is
crossed, the only map scale views available are 4 mi,
8 mi, 31 mi, and 128 mi (8 km, 16 km, 64 km and
256 km). Change the selected search area region when
you get closer to the destination. See “Setting the Search
Area” underMaps on page 4-38for more information.
Keyless Access System
When the engine is started, Driver 1 or Driver 2 displays
on the screen. A message will not appear on the
screen if the driver is unknown. The number on the back
of the transmitter corresponds to driver 1 or driver 2.
The navigation system can store memory points for
drivers 1 and 2 individually. SeeKeyless Access System
Operation on page 2-5for more information.
OnStar®System
When using the OnStar®system, the audio system
mutes and the navigation voice prompts become
disabled during the call. The volume of the OnStar call
can be adjusted by using the steering wheel volume
controls. SeeOnStar
®System on page 2-42for
more information.

Ordering Map DVDs
The map DVD in the vehicle is the most up-to-date
information available when the vehicle was produced.
The map DVD is updated periodically, provided that the
map information has changed.
If there are any 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 you need any updates or a replacement disc, because
the current disc is lost, damaged, or needs to be updated,
call the GM Nav Disc Center or order a new disc online.
To order a disc, have your Vehicle Identi cation Number
(VIN) available. This helps the center make sure you
receive the correct and most up-to-date DVD map disc for
your vehicle. SeeVehicle Identification Number (VIN) on
page 6-81for more information.
After receiving the updated disc, replace the old disc in
the navigation system. See “Installing the DVD Map Disc”
and “Ejecting the DVD Map Disc” underMaps on
page 4-38. Dispose of the old disc to avoid confusion
about which disc is the most current.
Database Coverage Explanations
Coverage area depends upon the map detail available.
Some areas have greater map detail than others. The
navigation system works only as well as the information
provided on the map disc. SeeOrdering Map DVDs on
page 4-52on how to obtain updated map information.
Navigation Audio System
Notice:Before adding any sound equipment to the
vehicle, such as an audio system, CD player, CB
radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound equipment
can be added, it is very important to do it properly.
Added sound equipment can interfere with the
operation of the vehicle’s engine, radio, or other
systems, and even damage them. The vehicle’s
systems can interfere with the operation of sound
equipment that has been added.
The vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be played
even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-25for more
information.
The audio system is operated using navigation system
menus. The audio menus are explained in this section.

audio screen.
Preset Selection:The audio system’s presets can be
programmed to recall the home settings by touching
HOME. The presets used when traveling can also be
recalled to another area by touching AWAY. See “Preset
Station Menu” later in this section for more information on
how to store preset stations.
The Home and Away feature is not available for the XM™
Satellite Radio source, if equipped.Display Presets on the Map:With this feature on,
the audio system presets for the current audio source
displays on the left of the map screen. Touch ON to turn
this feature on. This feature can also be turned off.
With this feature on, the preset radio stations can be
recalled from the map screen. Preset stations from
the map screen cannot be stored. This must be done
from the audio screen. See “Preset Station Menu” later
in this section for more information on storing presets.
Noise Compensation Technology:The system
is equipped with Bose
®AudioPilot®noise compensation
technology. AudioPilot continuously adjusts the audio
system equalization to compensate for the background
noise, so the music sounds the same, even as the
background noise levels change.
To use AudioPilot
®, press the ON screen button.
To turn it off, press the OFF screen button.
This feature is most effective at lower volume settings
where background noise can affect how well the music
being played through the vehicle’s audio system is heard.
At higher volume settings, where the music is much
louder than the background noise, there may be little or
no adjustments by AudioPilot
®.

®, visit

Radio Data Systems (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information. With RDS, the radio can:
Seek to stations broadcasting the selected type of
programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
Seek to stations with traffic announcementsRDS:Touch RDS to use alternate RDS functions
located in the preset menu. After touching RDS, there
is about ve seconds to choose RDS ON/OFF, TA,
MSG, PTY, or SEL PTY. If no selection is made, the
system returns to the previous menu.
If tuned to a station broadcasting RDS information, the
station’s Program Service (PS) and Program Type (PTY)
will replace the station’s frequency on the status line
at the top of the display. After about ve seconds, if
available, the PTY will be replaced on the display by the
station’s PTY name. The PTY and PTY name may be the
same or different.
If the audio system is tuned to a station that is not
broadcasting RDS information, the station’s frequency
remains on the display. While RDS is on, the audio
system searches for a stronger station in the network
if a station gets too weak for listening.
The RDS feature relies upon receiving speci c
information from RDS stations. These features only
works when RDS information is available.
TA (Traffic):Touch TA to receive traffic announcements.
The audio system turns on the TA display. TA appears on
the display if the current station broadcasts traffic
announcements. Traffic announcements can also be
