Problem Solution
Why does the Disclaimer screen need to be displayed every
time I start the car? I am the only driver. The
Disclaimer screen reminds you and your guest drivers to always
operate the navigation sy stem in a safe manner.
The Setup or Information screen has “grayed out” items that
I cannot select. Why? You need to select
OK on the Disclaimer screen to view these items. See
System Function Diagram on page 26.
I tried entering an address, but th e city or street could not be
found. Is there any other way to route to the location? Some cities are lumped in with a major metro area Try entering the street
first. In rural “unverified” areas
or new subdivisions, streets may be
missing, or only partiall y numbered. Try selecting the destination directly
from the map. See By Map Input on page 45.
When I enter an address, some letters become grayed out. Is
this normal? Yes, as you enter each letter in an addr
ess or a point of interest (POI), the
system looks in the databa se to see what letters are possible and “grays out”
letters that do not apply.
How do I delete Personal Address, Previous Destinations, or
the Home Address? This is done in Setup, under “P
ersonal Information.” See page 84.
I cannot hear the navigation system voice. 1) Ensure that Volume in the Setup screen (first) is not OFF. See page 83.
2) Go to “Basic Settings” in the Setup screen (second), and set Voice
Recognition Feedback to ON . See page 90.
The voice control system is ha ving difficulty recognizing my
Voice commands. Ensure that the vents are not blowi
ng on the microphone on the ceiling, the
vehicle is as quiet as possible, and that you are using the correct command
when speaking (See Improving Voice Recognition on page 14). Say “Help”
at any screen to see a list of the applicable voice commands.
When the system pronounces the street name in the guidance
command, or reads the destinat ion address it sounds strange.
What causes this? The basic guidance phrase uses a studio
-recorded voice, but the street name
is pronounced by the system us ing a machine-generated voice.
Consequently, the name may be misp ronounced or sound strange at times.
When I drive at night, the screen is bright and will not switch
to the night display mode. Why? Verify the following: The disp
lay mode in Setup is set to Night mode, the
dash brightness is not set to maximum, and Map Color in Setup is set to
Black for Night. See Switching Display Mode on page 104.

Frequently Asked Questions
The daytime map screen is dark like the night display mode,
and it is hard to see. Why? Verify the following: The disp
lay mode in Setup is set to Day mode, and
Map Color in Setup is set to White for Day. See Switching Display Mode
on page 104.
During the day, I turned on the lights because it started to
rain, but the screen went dark. How can I make it still display
day mode? Adjust the dash brightness (+) knob to fu
ll brightness. Remember to set it
back to a medium setting, or at ni ght, the screen will be bright. See
Switching Display Mode on page 104.
How can I input my destination using map coordinates? The navigation system was not designed for this. However, you can view
the coordinates of an address by pushing in on the Interface Dial, selecting
Show Icon on Map , and moving the Interface Dial left to select
Current Location . See Displaying Current Location on page 21
How do I change or remove my PIN? Go to “Personal Information” in the Setup screen (second) , and select PIN
Number . Enter your existing PIN, and then you have the choice to change
or remove the PIN. See page 88.
I forget the PIN. How do I reset it? PINs are optional. See information regarding PINs on page 88. Your dealer
can reset the PIN for you.
I change my setup settings, bu t they are not saved when I
restart the vehicle. Verify that your Remote Keyless
Entry is linked (The MID shows
“Welcome drive 1” or “Welcome dr iver 2”). See page 18 for additional
information.
I cannot access my Calendar or Address Book. Why?
CALL is not available on the Calculate route to screen.
Why? Your phone is not “paired” to the HFL,
or if your phone is “paired,” it is in
use; press HFL BACK button.

Frequently Asked Questions
Guidance, Routing
Problem Solution
The navi does not route me the same way I would go, or the
way some other mapping progr am displays. Why is this? The navigation system attempts to
generate the optimum route. See
Changing the Routing Method on page 51.
Why is the street I’m on not shown on the map? It has been
here for more than a year. The mapping database is
constantly undergoing revision. See page 116 for
ways to obtain the latest de tailed coverage information.
The vehicle position icon is not following the road and the
“GPS icon” text in the upper left hand corner of the screen is
white or missing.  The GPS antenna (located under the center of the dash) may be blocked by
personal items. For best reception, remove items from the dash, such as
radar detectors, cell phone s, or loose articles.
 Metallic tinting or other after-marke t devices can interfere with the GPS
reception. Please see your dealer. Also see System Limitations on
page 111.
I entered a destination, but th e blue highlighted route and
voice guidance stopped, or turned into a blue/purple dashed
line before I got to my destination. Why is this? Your route has entered
an unverified area. See Unverified Area Routing on
page 92.
The map rotates while I make a turns, How can I stop this? Select the “North-up” map orientation by voice, or by selecting “North-up”
from the map menu. See Map Orientation on page 61.
Sometimes I cannot select between the North-up, and
Heading-up map orientations, why is this? The “Heading-up” map orientation can
only be shown in the lower scales
(1/20 - 1 mile scales). See Map Scale on page 60.
While driving to my destinati on, the “time to go” display
sometimes increases even though I am getting closer. The “Time to go” is based on actual
road speeds. However if you speed
slows down when you encounter slower traffic, the system updates the
“Time to go” based of your actual spee d to give you a better estimate of
arrival time.
The vehicle position icon on the map “lags” a short distance
behind especially when I arrive at an intersection. Is there
anything wrong? No, when at an intersection, the syst
em is unaware of the width of the
intersecting road. Large differences is vehicle position can indicate a
temporary loss of the GPS signal. See GPS Reception Issues on page 111.

132Navigation System
Frequently Asked Questions
While I drive, my screen shows white dots (“breadcrumbs”)
on it. What do they mean? These are called “breadcrumbs.”
If you drive more than 1/2 mile from
mapped roads, the off-road tracking feature begins to function. See Off-road
Tracking on page 67 and 101.
How can I get rid of the whit e dots (“breadcrumbs”) from my
screen? Go to “Vehicle” in the
Setup screen (second), and set Off-road Tracking
to OFF, then return to the map. See page 101.
A road that I selected to avoi d is being used when routing.
What is wrong? When you “draw” your area to avoid, make sure to select sections of roads
that include at least one
intersection. See page 96.
When I arrive at my destination, the “bulls-eye” is shown at a
different location on the street. Why? The system calculates the “bulls-eye
” location based on the street address
range allocated for that street. See Destination Icon on page 62 for an
example.
My elevation (shown when I di splay the current position)
seems to fluctuate even though my elevation has not changed. This is normal, and due to errors in sa
tellite position. The elevation can vary
+/- 100 feet. See System Limitations on page 111.
My elevation is missing on th e “current position” screen.
Why? If the GPS antenna cannot receive at leas
t 4 satellites, the elevation is not
displayed. Try moving the vehicle into an open area. If the elevation is zero,
or below sea level, the elev ation is also not displayed.

Frequently Asked Questions
Ordering a Navi DVD, Coverage, Map Errors, Limitations
Problem Solution
I want to buy a new DVD. How do I purchase one? You cannot obtain a new DVD from the dealer. See Obtaining a Navigation
Update DVD on page 116.
I want to order a DVD. How ca n I determine the DVD version
in my navigation system? The version is on the label of your DVD. It starts with “Ver:.” See
Changing
the DVD on page 116.
I got a Navi DVD from a “friend,” but it does not work. Why? Your vehi cle was designed to use a white DVD. DVDs with different
colored labels, or from different manuf acturers, will not operate correctly.
Always obtain DVDs from the DVD order desk. See page 116.
When is my city going to become part of a fully verified
detailed coverage area? The mapping database vendor is constantly revising map coverage. See
page 116 for ways to obtain the latest
detailed coverage information.
Will the navigation system work outside North America? The navigation system contains maps only for the lower 48 states, and portions of southern Canada. The system will not work in Mexico, Hawaii,
Alaska, or overseas. Canada coverage is limited. See Map Coverage on
page 118.
Can I play video DVDs in my navigation sy stem?No. The navigation system is desi gned only to read the white DVD provided
with your vehicle. Map di scs for other vehicle manufacturers, or PC map
programs will not work.
I found some errors in the database. How do I report them? Mi nor errors are bound to occur in a large database. If you encounter major
errors, you can report them following the instructions on page 114.

Frequently Asked Questions
Display, Accessories
Rear Camera
Miscellaneous Other Questions
ProblemSolution
The display appears dim when starting the car in real cold
weather. Is there a problem? No, this is normal, and will beco
me brighter after a few minutes.
Problem Solution
When I shift gears, the rear camera image is delayed. When shifting into or out of reverse, you may experience delays when the
screen image switches between the navi screen and the rear camera image.
This is normal.
The rear camera image is too dark or too bright, how do I
adjust the brightness. While the camera image is displayed, use the Zoom In/Zoom Out controls to
adjust the brightness. This ad
justment does not affect the Setup screen
brightness adjustments.
Problem Solution
My clock frequently changes forward and backward by one
hour. Why is this? The clock is being automatically set based on your GPS location. If you live
and work on the boundary between two
time zones, you can turn off this
feature. See page 100.
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 100.
My state does not observe dayl ight savings time. How do I
turn off this feature? You can turn off this feature. See page 100.

Navigation System135
Frequently Asked Questions
Daylight savings time occurred, but the navigation system did
not change time even though Setup shows “Auto Daylight” is
“ON.” Go to the Clock Adjustment
screen in Setup and simply turn off the auto
daylight savings time feature, select Time Adjustment , and adjust your
clock
using the Interface Dial by one hour. For more information, see
Clock Adjustment on page 99.
The navigation system automatic daylight time feature is not
switching the navigation system clock on the correct dates.
Why is this? The Navigation system is designed to
switch to daylight savings time in
April/October. For more information, see Clock Adjustment on page 99.
The navigation system clock switched by one hour for no
apparent reason. Wh at can cause this? 1) You may be near a ti
me zone boundary…(Covered in the other “clock”
FAQs)
2) The navigation system is still swit ching per the old Daylight savings
schedule (April/October). Set the “Auto Daylight” to “OFF” on the
Clock Adjustment screen in Setup. Manually adjust the clock by one
hour as needed. See page 99 for more information.
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.
