Also, depending on your current view
of the sky and the position of the
satellites, the elevation may be shown
incorrectly.
You may also notice some delay of the
vehicle position icon at intersections;
this is normal.
GPS Reception Issues
The signals received from the GPS
satellites are extremely weak (less
than a millionth of the strength of
a local FM station) and require an
unobstructed view of sky. The signal
can easily be interrupted or interfered
with by the following:
• Aftermarket metallic window tint
above or to the sides of the GPS
antenna (located on the back of the
navigation display)
• Cell phones, PDAs, or other electronic devices docked in a cradle
or lying loose on the dashboard
• Remote starters or “hidden” vehicle tracking systems mounted near the
navigation unit • Other aftermarket audio electronic
devices mounted near the navigation
unit
• Trees, tall buildings, freeway overpasses, tunnels, or overhead
electrical power wires
Although the system will direct you
to your desired destination, it may not
always generate what you consider to be
the most direct route. Try changing the
method of routing. See Changing the
Routing Method on page 53 . You may
also have Unver ifi ed Area Routing set
to OFF. See Unverifi ed Area Routing
on page 103 .
Additionally, the mapping database
contains verifi ed and unverifi ed maps.
See Map Overview on page 6 . A
Disclaimer screen will warn you if
your route includes unverifi ed streets.
Unver ifi ed streets may be missing from
the map, in the wrong location, or have
an incorrect name or address range.
Exercise additional caution when
driving in these unverifi ed areas. The destination icon shows the
approximate location of the destination.
This occurs because a city block can
have as many as 100 possible addresses
(for example, the 1400 block is followed
by the 1500 block) Since most cities
use only a portion of the 100 possible
addresses (for example, in the 1400
block, the addresses may only go up to
1425 before the 1500 block starts), the
address 1425 will be shown a quarter of
the way down the block by the system
instead of at the end of the block where
the destination is actually located.
You may fi
nd that the system
occasionally reboots. This is indicated
by the display returning to the globe
screen. A reboot can be caused by a
number of things, such as extreme
temperatures or shock from bumpy
roads. It does not necessarily indicate
a problem that requires service. If this
happens frequently, please see your
dealer.

Coverage Areas
142 Navigation System

Operation in Alaska, Hawaii,
Canada, and Puerto Rico
Certain functions that rely on a satellite
signal will not work correctly. These
functions include but are not limited to
AcuraLink, NavTraffi c and Weather.
XM Radio
Navigation-equipped veh icles delivered
to Alaska, Hawaii, Canada, and
Puerto Rico are equipped with XM
hardware, but XM broadcasting is
not available; therefore sections of
the manual that mention XM audio,
traffi c displays, weather information,
and AcuraLink features do not apply.
Vehicles originally delivered to the U.S.
mainland and shipped to Hawaii also
have XM, but will not function because
the XM satellites (aimed toward the
U.S. mainland) are too far away to
obtain reception.
Alaska, Hawaii, Canada, and
Puerto Rico
This section describes the differences in
navigation system operation for vehicles
delivered in Alaska, Hawaii, Canada,
and Puerto Rico.
Map Coverage
All roads displayed on the map screens
are detailed coverage roads. Text related
to “unverifi ed” roads or areas are not
applicable. The following topics do not
apply:
• Unverifi ed road descriptions (see
page 7, 103 )
• Cautions and pop-up windows related to unverifi ed roads (see page 72 )
• Setup entries that relate to turning on or off unverifi ed routing (see page
10 4 )
Other Map Issues
• See the coverage section for a list of
islands with coverage (see page 131 )
Address and POI Entry Screens
The following differences occur for
map, address, and POI selection:
• Entry of a destination address or POI on an island other than your current
island may result in a screen caution
message. This is normal because
there are no “ferry” routes between
islands available in the database.
Setup Screen Differences
The SET UP screen differences are
minor and are listed below. See the
Setup section (pag e 93 ) for additional
information.

Traf c
Problem Solution
My Real-Time Traffi c is missing and is not displaying
properly. What is wrong? y Verify the following:
• Check the traffi
c icon on the icon bar, and the icon options for traffi c. Page
68 walks you through the verifi cation steps.
• Your XM NavTraffi c subscription may have 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 pag e 121 for the status of your subscription.
• It is possible that there is a temporary technical problem with your metropolitan area traffi c. You can call Acura Client Services to see if there
is an outage (pag e 128 ).
• 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 Traffi c
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 fi
nd a
considerably faster route than the original one.
While traveling on my route on the freeway, the system
has me exit and take an alternate freeway with unknown
fl ow speeds or surface streets. Why is this? Based on freeway congestion along your route, the system predicted that
taking an alternate freeway or surface streets would be faster. Use your own
experience to determine whether the alternate route would be faster.
How can I ignore the detour route and return to the
original route? Tu r n Tr a f fi
c Rerouting to OFF in Setup, under Routing & Guidance (pag e 110 ).

Frequently Asked Questions
148 Navigation System
Problem Solution
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
Tr a c k i n g on page s 70 and 112 .
How can I get rid of the white dots (“breadcrumbs”)
from my screen? Go to “Vehicle” in the SET UP
screen (Other), and set Off-road Tracking
to OFF , then return to the map. See pag e 112 .
A road that I selected to avoid 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
107 .
My elevation (shown when I display the current position)
seems to fl uctuate even though my elevation has not
changed. This is normal and due to errors in satellite position. The elevation can vary
+/- 100 feet. See
System Initialization on page 123 .
My elevation is missing on the “current position” 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 below sea level, the elevation is also not displayed.
