2012 Acura TL Navigation Manual

System Initialization
128 Navigation System

System Initialization
If for any reason you lose power
to the vehicle (e.g., the battery is
disconnected), the navigation and audio
system will require initialization. Once
completed, your system will be ready
to use.
This initialization requires the
following:
• Entry of the 5-digit anti-theft security
code to “unlock” the navigation and
audio system.
• GPS initialization (may not be needed depending on the length of
time the system was without power).
(See GPS Initialization o n p a g e 1 2 9 . )
• Map matching to align the GPS coordinates to a place on the map
(displays current street at the bottom
of the map). (See Map Matching on
page 129 .)
Entering the Security Code
When you purchased the vehicle,
you should have received one card
containing a 5-digit anti-theft code
used to activate both the navigation and
audio system.
Enter the 5-digit security code in
accordance with the instructions in your
owner’s manual. If you do not enter the
security code, navigation, audio, and
voice recognition will not function.
If you lose the card or do not have
access to it, you can retrieve it using
one of the following methods:
1) G o t o www.myacura.com , if you
previously set up your account in
accordance with the vehicle owner’s
manual.
2) Call Acura Client Relations at (800) 382-2238.
3) Visit your dealer.
You will need your radio serial number
and vehicle VIN to retrieve the anti-
theft code. To retrieve the radio serial number,
press and hold the audio preset 1 and 6
buttons. Continue to hold the buttons,
then turn on the radio. Record the serial
number shown on the radio display.
NOTE:
The anti-theft security code is
unrelated to your optional navigation
system PIN (for Address Book or Home
Address) .

GPS Initialization
Depending on the length of time the
battery was disconnected, your system
may require GPS initialization. If it
does, the following screen appears:
If this procedure is not necessary,
the system proceeds directly to the
Disclaimer screen (see page 18 ).
During initialization, the system
searches for all available GPS satellites
and obtains their orbital information.
During this procedure, the vehicle
should be out in the open with a clear
view of the sky. If the navigation system fi
nds the
satellites properly, this box clears and
the Disclaimer screen is shown. If
within 10 minutes the system fails to
locate a suffi cient number of satellites
to locate your position, the following
screen appears:
If the system is still unable to acquire
a signal, follow the instructions on the
screen, or contact your local dealer for
assistance.
NOTE:
The average acquiring time is less than
10 minutes.
Map Matching
This part of the initialization matches
the GPS coordinates found above with a
road on the map screen. To perform this
part of the procedure, ensure that the
navigation system is displaying a map,
and drive the vehicle on a mapped road
(a road shown on the map screen). Do
not enter a destination at this time.
When the name of the current road you
are driving on appears at the bottom
of the screen, the entire procedure is
complete. Your system is now ready to
use.

System Initialization
130 Navigation System
Although your navigation system is one
of the most highly sophisticated pieces
of equipment you will fi nd in a modern
automobile, you may fi nd during its use
that it has certain limitations.
The system uses GPS signals to aid
in determining its current location.
The GPS is operated by the U.S.
Department of Defense. For security
reasons, there are certain inaccuracies
built into the GPS that the navigation
system must constantly compensate for.
This can cause occasional positioning
errors of up to several hundred feet.
For example, in urban areas where
streets are close together, this could
cause the system to show that you are
traveling on a street that parallels the
street you are actually on. The system
will, under most circumstances, correct
itself while you drive.

System Limitations
Navigation System131
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 10 8 .
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.
System Limitations

Database Limitations
132 Navigation System
You will fi nd that some points of
interest (POI) may be missing when you
search the database. This can be caused
if at the time the database was gathered,
the name was misspelled, the place
was improperly categorized, or the POI
change is not yet in the database. This
means you may not fi nd places listed
that you know exist. This is also true
for police agencies and hospitals. In
outlying areas, facilities listed may not
be the closest. Always check with local
information sources if you need law
enforcement or hospital services.
Every effort has been made to verify
that the system’s database was accurate
at the time it was created. However,
businesses do close or relocate, and new
businesses start in the old locations.
For this reason, you may occasionally
fi nd inaccurate information when you
select and drive to a point of interest
(for example, a restaurant is now a
jewelry store). The number of these
inaccuracies increases the longer you go
without an update. The digitized map database refl
ects
conditions as they existed at various
points in time before production.
Accordingly, your database may contain
inaccurate or incomplete data or
information due to the passage of time,
road construction, changing conditions,
or other causes.
Due to ongoing software and database
improvements, navigation software and
mapping versions versions may change
in the middle of a production year. The
version shipped with your vehicle was
the most recent available at the time of
production and is considered standard
equipment for that vehicle. There is no
free program to retrofi t early production
vehicles with the latest software and
mapping versions. For update DVD
ordering information, see page 135 . In addition, this database does not
include, analyze, process, consider, or
refl
ect any of the following categories
of information:
• Neighborhood quality or safety
• Population density
• Availability or proximity of law enforcement
• Emergency, rescue, medical, or other assistance
• Construction work, zones, or hazards
• Road and lane closures
• Legal restrictions (such as vehicular type, weight, load, height, and speed
restrictions)
• Road slope or grade
• Bridge height, width, weight, or other limits

Reporting Errors
Occasionally, you may encounter
database errors.
• If the error pertains to freeways and
main “verifi ed” roads shown in black
on the map, then report it online at
http://update.navteq.com / .
• If the error involves a purple “unverifi ed” road, then do not report
it. These areas have not been verifi ed
and are provided for reference only
(see Map Overview on page 6 ).
• For errors in points of interest (POI), like a business that has changed its
name, do not report them. Keep in
mind that depending on when the
data was collected, the database can
be out of date. The business may
have not reported the change(s), or
not be in the database at all. Update
Navigation DVDs are available for
purchase, usually in the fall of each
year. See Obtaining a Navigation
Update DVD on page 135 regarding
updates to the navigation system. • If the error does not involve the
database, such as vehicle position
icon error, screen error messages,
or other GPS related errors, see

Visiting Your Dealer
We strive to make this manual as
complete as possible and to answer all
questions regarding operation of the
system. Occasionally, you may run into
a specifi c issue that you cannot fi nd
in the book. You may save yourself a
trip to the dealer by fi rst consulting the
following resources:
• The Troubleshooting section (see page 163 )
• The Frequently Asked Questions (FAQs) section (see page 155 )
• The FAQs found on the online update DVD order site (see “Obtaining a
Navigation Update DVD”)
• For detailed questions regarding HFL, audio, or other systems that
interact with the navigation system,
see your owner’s manual, or the
Advanced Technology Guide.
• For traffi c-related issues, see the
“ AcuraLink Real-Time Traffi c™ ”
section (on page 23 ) and FAQs (on
page 155 ). • Call Acura Client Relations (see
Acura Client Relations on page 134 ).
• For database or POI issues, follow the guidelines in the “ Reporting Errors ”
section (see page 134 ).
If your question is still unanswered
and you wish to visit the dealer, please
be prepared to demonstrate the issue
to the service consultant. That way,
the service consultant can document
the issue for the factory to allow more
effi cient troubleshooting.
Some issues may at fi rst seem random,
but you may notice a pattern, like they
only occur when you enter a specifi c
address, when driving on a certain road,
or just when it’s cold. This information
is very useful to the service consultant.
Be patient, the service consultant may
be unfamiliar with your specifi c issue. Obtaining a Navigation
Update DVD
Acura is continually expanding the
scope of the navigation system.
Upgraded software may be made
available to navigation system owners
periodically, usually in the fall of each
yea r.
To purchase an updated DVD, you will
need your vehicle’s VIN number and the
System/Device Information from the
INFO screen (Other). Call the Acura
Navigation Disc Fulfi
llment Center at
