NAVIGATION SYSTEM OPERATION
Selecting a Destination
A destination can be selected by Address, Intersection,
Place, Personal Address, Previous Destination, Map
Input, or Today's Destinations using the touch-screen,
the joystick, or the voice control system. Refer to the
Navigation System Manual for detailed information.
Traveling to a Destination
Confirm a selected route – The system display asks
you to select one of these route options:
• Direct Route – Takes the least amount of time
• Easy Route – Minimizes the number of turns
• Minimize Freeways – Avoids freeway travel (when
possible)
• Minimize Toll Roads – Avoids toll roads (when
possible)
• Maximize Freeways – Incorporates freeway travel
(when possible)
Going off the route – If you leave the route, the
system recalculates the route from your current
position, and displays a new highlighted route.
Modifying the route – The system can recalculate
portions of the route and/or avoid a specific street, and
then return you to the current route.
Save current location – This option stores the current
location for later use (it does not change or cancel the
route instructions currently in progress). A location can
be stored anytime the navigation system is in use.
Off-road tracking – This option displays dots ("bread
crumbs") on the map if you drive on a road not shown
on the navigation screen. These bread crumbs begin to
appear approximately ½ mile away from a mapped
road, and they allow you to retrace your route back to a
mapped road. They will not appear if this feature is
turned off during setup.
Personal Addresses
Two users can each store up to 100 destinations
(addresses with phone numbers) in the system. A PIN
(Personal Identification Number) is optional. Refer to
the Navigation System Manual for instructions on how
to enter a PIN and use Personal Addresses.
Go Home
This option allows a single button entry to set your
home address as a destination. A PIN is optional.

System Limitations
Always verify the audio and visual route information by
carefully observing roadway signs, signals, etc. Use
your own good judgment, and obey traffic laws while
driving. The navigation system has these limitations:
• The GPS (global positioning system) satellites used
by the navigation system are operated by the U.S.
Department of Defense. For security reasons,
certain inaccuracies are built into the GPS. This can
cause occasional positioning errors of up to several
hundred feet. If the navigation system indicates your
position incorrectly, wait several seconds until it
corrects itself. The system may also correct itself
after you make a turn or cross a road.
• The routes calculated by the system may not always
be what you consider to be the most direct ones. Try
different routing methods to obtain the best route.
Even the direction your vehicle is pointing influences
the route calculation.
• Since businesses fail or move to new locations,
some information may be inaccurate. Also, route
guidance may conflict with actual road conditions
such as street closures, construction, and detours.
• Occasionally, the navigation system may "reboot"
due to excess heat or shock, or from recalculating a
route too many times. Rebooting does not
necessarily indicate a need for service.
• GPS reception is affected by outside electrical
interference from aftermarket electronic devices
placed near the GPS antenna or navigation unit.
Aftermarket metallic tinting of windows above the
GPS antenna, that is located beneath the package
tray, can seriously degrade the GPS signal.
NAVIGATION SYSTEM SETUP AT TQI
The navigation system must be allowed to initialize
itself before use. During initialization, the system
obtains the orbital information of the GPS satellites.
When initialization is complete, the system can "locate"
itself and function normally. To initialize the system,
follow this procedure:
1. Perform the normal TQI of the vehicle, including the
audio system. The AUDIO button and the
navigation system voice will not function if the 5-
digit anti-theft code for the audio system has not
been entered.
