Map and Features, Voice Oper ation, Entering Addresses
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.
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 page46.
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 Addre sses, Previous Destinations, 
or the Home Address? This is done in the 
SETUP screen ( Main Setup ), under “Personal 
Information.” See page 95.
I cannot hear the navigation system voice. 1) Ensure that Volume in the SETUP  screen (Main Setup ) is not OFF. 
See page 95.
2) Go to “Basic Settings” in the  SETUP screen ( Other), and set  Voice 
Recognition Feedback  to ON . See page 104.
The voice control system is ha ving difficulty recognizing my 
voice commands. Ensure that the vents are not blowing on the microphone on the ceiling, the 
vehicle is as quiet as 
possible, and you are using the correct command when 
speaking (see  Improving Voice Recognition  on page14). Say “Help” at any 
screen to see a list of the applicable  voice commands. If the system cannot 
recognize your command because of  background noise, speak louder.
When the system pronounces the  street name in the guidance 
command or reads the destinati on 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: Th
e nighttime dash brightness control is not set to 
maximum, and  Map Color in SETUP is set to  Black for Night. See 
Switching Display Mode Manually  on page118.

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 
Map Color in SETUP is set to  White for Day. 
See  Switching Display Mode Manually  on page118.
How do I change or remove my PIN? Go to “Personal Information” in the  SETUP screen ( Main Setup ), and 
select  PIN Number . Select GO Home 1 PIN  or GO Home 2 PIN  or 
Address Book PIN  and enter your existing PIN.  You then have the choice 
to change or remove the PIN. See page 100.
I forgot the PIN for Home, or  the PIN for personal addresses 
(DRIVER 1 or DRIVER 2). How do I reset it? PINs are optional. See information re
garding PINs on page100. Your dealer 
can reset the PIN for you.
CALL  is not available on the  Calculate route to screen. 
Why? Your phone is not paired to HFL, or if
 your phone is paired, it is in use; 
press the HANG-UP button.

Frequently Asked Questions
Traffic
Problem Solution
My AcuraLink Real-Time Tra ffic is missing and is not 
displaying properly. What is wrong? Verify the following:
• Check the traffic icon on the icon ba
r, and the icon options for traffic. 
Page 62 walks you through the verification steps.
• Your XM traffic subscription may ha ve expired. Call XM at (800) 852-
9696 and verify your account status. If  your subscription has lapsed, you 
may need to request a “rapid refresh.” After XM refreshes your account 
status, leave the vehicle running outside for 30 minutes to receive the 
refresh. See page 124 for the status of your subscription.
• 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 132).
• If the situation persists, see  your Acura dealer for assistance.
• AcuraLink relies on a satellite signal. It will not work in Alaska, Hawaii,  Canada, and Puerto Rico.
When I am driving a route on the freeway and Traffic 
Rerouting is  ON, sometimes the system  provides a detour 
route. Why is this? The system will provide a detour route 
to your destination only if it can find 
a considerably faster route than the original one.
While traveling on my route on  the freeway, the system has 
me exit and take an altern ate freeway with unknown flow 
speeds or surface st reets. Why is this? Based on freeway c
ongestion along your route, the system predicted that 
taking an alternate freeway or surface  streets would be faster. Use your own 
experience to determine whether th e alternate route would be faster.
How can I ignore the detour route and return to the original 
route? Turn 
Traffic Rerouting  to OFF in SETUP, under Routing & Guidance 
(page 110).

Frequently Asked Questions
Guidance, Routing
ProblemSolution
The navigation system does not route me the same way I 
would go, or the way some ot her mapping program displays. 
Why is this? The navigation system attempts to 
generate the optimum route. See 
Changing the Route Preference  on page53.
The navigation wants to rout e me around potential traffic 
problems. How do I stop  these pop-up messages? This feature can be turned off. See 
Traffic Rerouting on page110.
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 page134 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 on the back
 of the navigation display) may be 
blocked by personal items.  For best reception, remove items from the 
dashboard, such as radar detector s, cell phones, or loose articles.
• Metallic tinting or othe r aftermarket devices can  interfere with the GPS 
reception. Please see  your dealer. Also see  System Limitations on 
page 129.
I entered a destination, but th e blue highlighted route and 
voice guidance stopped, or turned  into a blue/pink dashed line 
before I got to my dest ination. Why is this? Your route has entered 
an unverified area. See  Unverified Area Routing  on 
page 106.
The map rotates while I make turns. How can I stop this? Select the North-up map orientati on by voice, or by selecting North-up 
from the  Map menu . See Map Orientation on page 63.
Sometimes, I cannot  select between the North-up and 
Heading-up map orienta tions. Why is this? The Heading-up map orientat
ion can only be shown in the lower scales (1/
20 - 1 mile scales). See  Map Scale on page66.
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 your speed 
slows down when you encounter slower  traffic, the system updates the 
“Time to go” based on your actual spee d to give you a better estimate of 
arrival time.

Frequently Asked Questions
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 in vehicle position can indicate a 
temporary loss of the GPS signal. See  GPS Reception Issues on page129.
While I drive, my screen s hows 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 71 and 115.
How can I get rid of the white dots (“breadcrumbs”) from my 
screen? Go to “Vehicle” in the 
SETUP screen (Other ), and set Off-road 
Tracking  to OFF, then return to the map. See page 115.
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 page110.
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 Initialization  on page127.
My elevation is missing on the “current pos ition” screen. 
Why? If the GPS antenna cannot receive signals
 from at least four satellites, the 
elevation is not displayed. Try moving  the vehicle into an open area. If the 
elevation is zero, or belo w sea level, the elevation is also not displayed.

Frequently Asked Questions
Update DVD, Coverage, Map Errors, Limitations
ProblemSolution
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
134 for ways to obtain the late st detailed coverage information.
Will the navigation system work outside North America? The system c ontains maps for the 50 U.S. states, as well as for Canada and 
Puerto Rico. The system will not wo rk in Mexico or overseas. See Map 
Coverage  on page134.
Can I play video DVDs in my navigation  system?No. The navigation sy stem is designed only to read music discs and the 
update DVD provided with your vehicl e. The system cannot read other 
mapping databases or video DVDs. If  you experience any problems that you 
cannot resolve, please  contact your dealer.
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

Frequently Asked Questions
Display, Accessories
Rear Camera
Miscellaneous Other Questions
Problem Solution
The display appears dim when starting the car in really cold 
weather. Is there a problem? No. This is normal, and it will become 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 navigation 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 displaye
d, use the rotating portion of the 
Interface Dial  (knob ) to adjust the brightness . This adjustment 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 ba
sed on your GPS location. If you live 
and work on the boundary between two  time zones, you can turn off this 
feature. See page 115 (Auto Time Zone).
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 115 (Auto Time Zone).
My state does not observe dayli ght saving time. How do I turn 
off this feature? You can turn off this feature. See page
114 (Auto Daylight).
