My Real-Time Traffic is mi ssing and is not displaying 
properly. What is wrong? Verify the following: 
 Check the traffic icon on the icon bar,
 and the icon options for traffic. 
page 65 walks you through the verification steps.
 Ensure that you have the correct remo te (the settings for driver 1 and 
driver 2 are set independently by each driver).
 Your XM “Nav Traffic” subscription  may have expired. Call XM at (800) 
967-2346 and verify your account status . If your subscription has lapsed, 
you may need to request a “rapid re fresh” after XM performs the refresh, 
then leave the vehicle running outsi de for 30 minutes to receive the 
refresh.
 It is possible that there is a te mporary technical problem with your 
metropolitan area traffic. You can call Acura Client Services to see if there 
is an outage (page 114).
 If the situation persists, see your  Acura dealer for assistance.

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.

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.

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.
