System Initialization
System Initialization
If for any reason, you lose power to the
navigation system (like the battery was
disconnected), the navigation system
will require initialization. Once
completed, your system will be ready to
use.
This initialization requires the
following:
 Entry of the 4-digit anti-theft security code to “unlock” the navigation
system.
 GPS initialization (may not be needed depending on the le ngth of time the
system was without power).
 Map matching to align the GPS coordinates to a place on the map
(displays current street at the bottom
of the map).
Entering the Security Code
If the battery goes dead or is
disconnected for any reason, you will
have to enter a security code for the
navigation system before you can use it
again.
When you purchased the vehicle, you
should have received two cards that
have the audio and navigation system’s
security codes and serial numbers. Keep
these cards in a sa fe place in case you
need the codes. If you lose the cards,
you must obtain the security codes from
your dealer. Enter the four-digit security code, then
select
Done. If you have entered it
correctly, the display changes to the
Disclaimer screen. If you make a
mistake, the system will display
“incorrect PIN.” Re-enter your 4-digit
security code. You have ten chances to
enter the correct code. If all ten are
incorrect, turn the i gnition to OFF, then
back to ON (II) to have ten more
chances to enter the correct code.
Follow the instructio ns in the vehicle
Owner’s manual to enter the 5-digit
audio code. The navigation voice will
not operate if the audio code is not
entered.
NOTE:
The anti-theft security code is unrelated
to your optional Navigation system PIN
(for Personal or Home Address).

System Initialization
GPS Initialization
Depending on the length of time the
battery was disconnected, your system
may require GPS initialization. If it
does, the following screen appears:
If this procedure is not necessary, the
system proceeds directly to the
Disclaimer screen (see page17).
During initialization, the system
searches for all available GPS satellites,
and obtains their orbital information.
During this procedure the vehicle
should be out in th e open with a clear
view of the sky. If the navigation system finds the
satellites properly, this box clears, and
changes to the
Disclaimer screen. If
within ten minutes the system fails to
locate a sufficient number of satellites to
locate your position, the following
screen appears:
After 30 minutes with this screen
displayed, turn off the engine and restart
the car. If you now see the Disclaimer
screen, the GPS initialization is
complete. The green GPS icon should
appear in the upper left corner of the
screen. NOTE:
 The average acquiring time is less
than 10 minutes, but it can take as
long as 45 minutes.
 If the system is still unable to acquire a signal, follow the instructions on
the screen, or contact your local
dealer for assistance.
Map Matching
This part of the initialization matches
the GPS coordinates found above with a
road on the map screen. To perform this
part of the procedure, ensure that the
navigation system is displaying a map,
and drive the vehicle on a mapped road
(a road shown on the map screen). Do
not enter a destina tion at this time.
When the name of the current road you
are driving on appears at the bottom of
the screen, the entire procedure is
complete. Your system is now ready to
use.
Navigation system is unable to acquire
a proper GPS signal.
- Move vehicle to another location.
- Turn the ignition switch off.
- Disconnect the battery for 30 minutes
to clear the GPS receiver’s memory.
- Reconnect the battery and follow
the screen prompts.

132Navigation System
Daylight savings time occurred,
but the navigation system did
not change time even though Setup shows “Auto Daylight
Saving Time” is “On.” Go to the
Clock adjustment screen in Setup and select DST Selection.
Ensure that the correct DST schedule is selected. For more information, see
Clock Adjustment on page 98.
The navigation system
automatic daylight time feature is not
switching the navigation system clock on the correct dates.
Why is this? 1) Go to the
Clock adjustment screen in Setup and ensure that Auto
Daylight Saving Time is On .
2) The navigation system is designed to switch to daylight savings time
according to the months selected in the DST schedule selection screen.
Ensure that the appropriate schedule is selected. For more information,
see Clock Adjustment on page98.
The navigation system clock switched by one hour for no
apparent reason. Wh at can cause this? 1) You may be driving near
a time zone boundary (see Auto Time Zone by
GPS on page 99).
2) The navigation system does not,
or incorrectly switches between
standard and Daylight Savings Time. Set Auto Daylight Saving Time
to On on the Clock adjustment screen in Setup, and ensure that the
correct month switching sc hedule is chosen on the DST schedule
selection screen. See page 98 for more information.
When driving near a time zone border, the time changes even
though I am not near the time zone. Why is this? The time zone borders are only appr
oximated in the system. Depending on
the geography of the time zone boundary, the switch to a different zone can
be erratic. See page 99.
My battery was disconnected, or went dead, and the
navigation system is asking for
a code. Where do I find this
code? There should have been a card in the
glove box with the anti-theft code for
the navigation/audio system. This card contains the 4-digit security code
and serial number. If you cannot find it, your de aler can help you out.
I speak a language other than English. When will other
languages be available fo r the navigation system? This is being considered
as a future enhancement.
