When replacing the navigation unit, this function allows
the dealer to transfer the client’s personal data to the
new navigation unit. The transferred information
includes their Setup settings, and personal addresses.
The dealer inserts a PC card to the navigation unit, and
then selects the Save Users Memory function. The two
functions in this diagnostic screen are EXPORT and
IMPORT. EXPORT saves the client’s data to the PC card,
andIMPORTmovesthePCcardfilestothenew
navigation unit.
Before starting this function, see the PC Card FAQs for
information regarding PC cards, and how to use this
function. 1. Select EXPORT button to move the client’s data
from the original navigation unit to the PC card.
Select YES on the Export User Data Confirmation
screen. The process takes only a couple of seconds.
The system stores two files on the card.
NOTE: If the EXPORT button is grayed out, check
the PC card’s edge connector, and the pins inside
the navigation unit (with a flashlight) for damage.
2. After installing the client’s original DVD in the new navigation unit, allow the system to boot up. Insert
the PC card in the new navigation unit and enter the
Save Users Memory in the navigation system
diagnostic mode.
3. Select IMPORT button to move the two files stored by the Export process from the PC card to the new
navigation unit. Select YES on the Import User Data
Confirmation screen. When the transfer is finished
(a few seconds) the system automatically reboots.
After the system reboots, remove the PC card from
the PC slot.
NOTE: If the IMPORT button is grayed out, check if
the Model and the Program Flash shown on the
Version screen are the same.

This screen is for factory use only, and should always
be set to OFF. Occasionally the DEMO setting is turned
ON when vehicles are being used at Auto Shows or
similar events. Turning this feature on, allows the
navigation system to automatically follow a route to a
destination when the vehicle is stationary. The Speed
changes the speed of the demo mode. This diagnostic allows you to independently test the
microphone and the navigation TALK and BACK
buttons. They are used to activate the voice control
system. The microphone is located near the map light
in the roof console. It is directional, and works only with
the voice coming from the driver’s seat.
 Press the navigation TALK button on the steering wheel, wait unit you hear a beep, and in a normal
voice say ‘‘testing’’. The TALK indicator on the screen
should momentarily turn green, and the text Now
Recording... should appear in yellow. If the talk
indicator shown on the screen does not briefly turn
green, check the wiring from the steering wheel
navigation TALK button to the navigation unit. If there
is no Mic Level movement when you speak, then you
should check the wires running from the microphone
in the roof console to the HandsFreeLink control unit
and the navigation unit. If the wires are OK, the
microphone must be faulty; replace the microphone
located in roof console (see page 23-358).
 PressthenavigationBACKbuttononthesteering wheel. This should cause the Cancel indicator on the

This screen shows the current status of GPS reception.
The circular diagram shows the current location of the
GPS satellites (yellow numbers) as they would appear
in the sky. The outer circle represents the horizon
(0 degrees elevation). The middle and inner circles
represents 30 and 60 degrees respectively. The very
center of the diagram (90 degrees elevation) is directly
overhead. Nearby obstructions, like tall buildings will
block satellites in that direction. That is why it is
necessary to be in an open area to effectively
troubleshoot GPS reception issues. The sate llite
numbers shown on the diagram correspond to the PRN
number in the GPS Details screen. There are always at
least 24 active GPS satellites in orbit. Because satellites
fail, and have to be removed from service, spares are
always parked in orbit, ready to be activated. This is
why the PRN (satellite ID number) can be greater than
24.
NOTE: When you use this screen for troubleshooting,
park the vehicle outside, away from buildings, tall trees,
and high-tension wires for at least 10 minutes with the
engine running.  The Number of Satellites box shows the number of
acquired satellites (maximum of 12). It should contain
three or more icons. If not troubleshoot for GPS icon
is white or not shown (see page 23-341).
 The Current Position shows latitude, longitude, and elevation (in feet). If there are less than four satellites,
the elevation can be grossly inaccurate.
 The Date/Time field shows the current date, and also a time that includes daylight savings and other
offsets entered by the customer in Setup screen 2
Adjust Time Zone/Clock.
NOTE: Pressing the map/guide button displays the
satellite number on each circle.

This diagnostic allows you to graphically display
problems with the yaw rate sensor.
 The ANG-Disp value accumulates any differences between the offset and sensor voltages (see Yaw
Rate diagnostic). When the sensor functions properly,
the random changes in these two voltages generally
cancels out, so the value is 0. However if one voltage
is consistently higher than the other, then the ANG-
Disp value accumulates the constant change.
 The Reset button temporarily clears the angular accumulation (ANG-Disp), and clears the display dots.
 Do not touch the CCW, CW, or Set buttons. These are used for factory setup only.
Two tests are explained below. For large problems with
the sensor values, the stationary test usually confirms
whether the sensor is defective. For yaw rate issues
related to driving, do the road test described below. 1. Stationary test: If the VP icon spins in place and the ANG-Disp value slowly increases or decreases in
value, the yaw rate sensor is defective. Replace the
navigation unit.
2. Road test: Drive the vehicle on a very straight road. Enter the diagnostic mode, select Yaw rate, and
touch the Tuning button. While driving down a
straight road, the white dots should trace a straight
line across the screen. However, if you are driving
on a straight road, and you notice the dots
constantly dropping down or heading up as you
drive, the navigation unit’s yaw sensor is defective.
You can touch Reset to clear ANG-Disp, and dotted
lines.
If either test above fails, please enter Yaw rate
sensor defective for the problem description, on
the Navigation core return form.
NOTE: The CCW, CW and Set buttons are disabled,
and cannot be activated. Use this screen to confirm that the navigation unit is
properly receiving input signals. Signals equal to (0) are
OFF, and signals equal to (1) are ON. If the value on the
display does not match the actual vehicle status, then
check the wire carrying the signal.
 VSP-Vehicle Speed Pulse from ECM/PCM (Connector A (24P) terminal No. 15)
a) OFF (0) when vehicle is not moving
b) ON (1) when vehicle is moving
The VSP comes from the ECM/PCM as a dedicated
signal. Internally, the navigation unit compares the
actual VP on the map against street data to adjust the
pulse to speed scaling factor. As this scaling factor
becomes more accurate, the Level gradually increases
from 0 to 10 (see the Tire Calibrate diagnostic screen).  BACK-Reverse indication from taillight relay (Connector C (8P) terminal No. 7)
a) OFF (0) when the shift lever is in any position other
than reverse
b) ON (1) when the shift lever is in reverse
The Back signal is used by the navigation unit to allow
the map screen to show the VP moving backwards
when in reverse. This signal is needed because the
Speed Pulse has no direction indication.

NOTE:
 Check the vehicle battery condition first.
 This is not the same condition as when driving off-road (or on a fire or logging road).
 This condition is caused by a loss of map matching from a bad sensor input. Check for aftermarket or
other objects that can block the GPS signal. Always
perform Map matching (see page 23-269) before
proceeding with the troubleshooting.
 Always check for and resolve all CAN DTCs before troubleshooting the navigation system.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode, and use
Version (see page 23-316).
 Make sure that the correct DVD color and version are installed.
 Check for aftermarket metallic window tinting.
 Inspect the DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
 Before troubleshooting, make sure you have anti- theft codes for the navigation system.
 After troubleshooting, enter the anti-theft codes for the navigation system.
 Check the DVD for damage or scratches.
 Check for connectors for poor connections or loose terminals.
1. Check the GPS icon on the navigation screen.
Do the troubleshooting for GPS icon is white
or not shown (see page 23-341).
Go to step 2.
2. Go into the Self-Diagnostic mode, and use the Yaw Rate diagnosis (see page 23- 314) to check the yaw
rate sensor.
Go to step 3.
Replace the navigation unit (see page 23-355). 3. Go into the Diagnostic mode, and use the Car
Status diagnosis (see page 23-315) to check the
vehicle speed pulse (VSP) and the BACK signals.
The problem may be a characteristic of the
system. Check to see if the problem occurs in the
same place in a known-good vehicle. If it does, the
problem could be in the database. Go to step 4.
 If the problem is the vehicle speed pulse, troubleshoot the vehicle speed signal circuit. BLU
wire for open or short. If OK, good ECM/PCM. If
the problem or symptom goes Update the ECM/
PCM (see page 11-227) if it does not have the
latest software or substitute a known-good ECM/
PCM (see page 11-228).
 If the BACK signal is indicated ON (I), when in any shift lever position other than reverse,
troubleshoot the back-up light switch circuit or
MICU (A/T).
4. Substitute a known-good navigation unit (see page 23-355), and check to see if the problem occurs in
thesameplace.
The problem is in the database and should
be considered a characteristic of the system.
Report the problem according to the Navigation
System Owner’s Manual under Reporting Errors
and look for improvements in future databases.
Replace the navigation unit (see page 23-355).

Introduction
Checking Cell Phone CompatibilityVoice Control Tips and Improving Voice
Recognition
23-361
The HFL system works only with Honda approved
Bluetooth
-enabled cell phones with a hands-free
profile. If you are not sure if a particular cell phone is
compatible with the HFL system, Acura has a dedicated
call center at 888-528-7876 and website www.acura.
com/handsfreelink to answer your questions.
The HFL system allows you to make and receive hands-
free calls. It cannot control the phone’s performance
(call quality and signal strength). For more information
about performance and performance problems, refer to
Dropped Calls.
The most important step in troubleshooting HFL issues
is to identify the model, software version, and wireless
carrier of the phone in question. Not all phones with the
Bluetooth feature and a hands-free profile are
compatible with the HFL system.
Go to handsfreelink.com, and check if the client phone
is approved to work with Honda HFL system.
NOTE:  The lists of approved, archived, and currently testing phones are constantly changing, so make sure you
view them frequently.
 Phones are added as they are approved.
 Phones can be removed from the approved list if a software bug is discovered that makes the phone
incompatible. These phones can be added back to the
approved list if the phone manufacturer corrects the
bug.
 If the software bug is corrected, a new software version is created and may be listed in the Supported
Features section of the phone.
 The software versions that are approved are now being listed in the Software Version field.
 If you cannot access the Acura website, call the HFL call center at 888-528-7876 for further assistance. The
call center is open Monday thru Friday from 6:00 a.m.
to 6:00 p.m. CT; Saturday from 7:00 a.m. to 6:00 p.m.
CT; and Sunday from 8:00 a.m. to 6:00 p.m. CT. To give a voice command to the HFL system, press and
release the HFL TALK button. Always wait for the beep,
then give your command in a clear, natural voice. The
HFL microphone is on the ce
iling by the map lights.
If the HFL system doesn’t recognize your voice
command, you’ll hear ‘‘Pardon.’’ If your command isn’t
recognized a second time, you’ll hear ‘‘Please repeat.’’
If your command isn’t recognized a third time, the HFL
system sends you to its Help menu.
To hear a list of available options at any time, press the
HFL TALK button and say ‘‘Hands-free help.’’
The HFL system may have problems recognizing some
voices. To improve voice recognition:
 Close the windows and the moonroof.
 Set the fan speed to low (1 or 2) or off.
 Adjust the airflow from the center vents down, so that it’s not blowing against the microphone on the ce iling.
 Speak in a clear and natural voice. If the system cannot recognize your command, try speaking louder,
in a deeper tone.
 If the background noise is too loud, you may need to speak louder.
 If you speak with something in your mouth, or your voice is too high, the system may not interpret your
command correctly.
 Find out if the problem is with one person or with everyone who uses the system. If the system has a
problem with only one person’s voice, this is a
system limitation.
