System Limitations
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 IssuesThe 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
Route Preference on page 53. You may
also have Unverified Area Routing set
to OFF. See Unverified Area Routing on
page 106.
Additionally, the ma pping database
contains verified and unverified maps.
See Map Overview on page 6. A
Disclaimer screen will warn you if your
route includes unverified streets.
Unverified 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 unverified 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 find that the system
occasionally reboots. This is indicated
by the display returning to the
navigation system 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.00 ACURA MDX_KA.book 129 ページ ２０１１年７月２７日　水曜日　午前１１時６分

Coverage Areas
Operation in Alaska, Hawaii,
Canada, and Puerto RicoCertain functions that rely on a satellite
signal will not work correctly. These
functions include but are not limited to
AcuraLink, and traffic- and weather-
related services.XM RadioNavigation-equipped vehicles 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, traffic 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 RicoThis section describes the differences in
navigation system operation for vehicles
delivered in Alaska, Hawaii, Canada,
and Puerto Rico.Map CoverageAll roads displayed on the map screens
are detailed coverage roads. Text related
to “unverified” roads or areas are not
applicable. The following topics do not
apply:
 Unverified road descriptions (see page 6, 106)
 Cautions and pop-up windows related to unverified roads (see page 72)
 Setup entries that relate to turning on or off unverified routing (see
page 106)
 See the coverage section for a list of islands with coverage (see page 134)
Address and POI Entry ScreensThe 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 DifferencesThe SETUP screen differences are
minor and are listed below. See the
Setup section (page 94) for additional
information.AcuraLink/MessagesThis item is grayed out on the SETUP
screen ( Other) because XM is not
available.Traffic & Weather StatusThis item is grayed out on the SETUP
screen ( Other) because XM is not
available.

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 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 page 124 for the status of your subscription.
 It is possible that there is a temporary technical problem with your metropolitan area traffic. You can cal l Acura Client Relations to see if
there is an outage (page 132).
 If the situation persists, see y our 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 rout
e than the original one.
While traveling on my route on the freeway, the system has
me exit and take an alternate freeway with unknown flow
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 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
The vehicle position icon on th e map “lags” a short distance
behind, especially when I arrive at an intersection. Is there
anything wrong? No. When at an in
tersection, the system is un aware 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 page 129.
While I drive, my screen s hows white dots (“breadcrumbs”)
on it. What do they mean? These are called “breadcrumbs.” If yo
u 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 page 110.
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 page 127.
My elevation is missing on th e “current position” screen.
Why? If the GPS antenna cannot receive signal
s 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.
