NOTE: Check the vehicle battery condition first.
 With good reception, the icon is normally green.
 Make sure the GPS antenna is plugged in.
 Check for any aftermarket accessories or metallic window tinting that may be interfering with the GPS
signal.
 Make sure the vehicle is parked outside, away from buildings.
 Refer to GPS Information (see page 23-312) for realtime satellite reception display.
1. Check for aftermarket metallic wi ndow tint on the
rear window and electronic aftermarket
accessories (possibly hidden) mounted near the
GPS antenna or the navigation unit.
Remove tint or the accessories, and
recheck.
Go to step 2.
2. Turn the ignition switch to ON (II).
3. Go into the Self-Diagnosis Mode, and use the System Links diagnostic (see page 23- 297) to check
the GPS antenna.
Check for a kinked, crushed, or disconnected
GPS antenna wire. If the icon is still red, replace the
GPS antenna (see page 23-358).
Check that nothing is blocking the GPS
antenna located under the package shelf and
recheck. Substitute a known-good GPS antenna,
and recheck.
 If the symptom is gone, replace the GPS antenna.
 If the symptom is still present, substitute a known-good navigation unit (see page 23- 355),
and recheck. If the symptom is gone, replace the
original navigation unit. NOTE:
 Check the vehicle battery condition first.
 Check the navigation volume level (see Owner’s Manual).
 Check the connectors for poor connections or loose terminals.
 If the Hard Error Code is stored, check the Hard Error Code troubleshooting first.
 Make sure that the correct DVD color and version are installed.
 Inspect the DVD for dirt or damage.
 Before troubleshooting, make sure you have anti- theft codes for the navigation system.
 After troubleshooting, enter the anti-theft codes for the navigation system.
1. Turn the ignition switch to ON (II).
2. Press the SET-UP button.
3. Check the volume and voice feedback setting for the navigation system in set-up.
Set the voice feedback to ON, and select an
audible level for the volume.
Go to step 4.
4. Check the audio system operation.
Go to step 5.
Troubleshoot audio system.
5. Select the Self-Diagnosis mode.
6. Check for error code to the Error History.
Refer to the Hard Error Code
troubleshooting.
Replace the navigation unit (see page 23-355).

NOTE:
 Check the connectors for poor connections or loose terminals.
 Before troubleshooting, get the navigation system anti-theft code, then write down the audio presets.
 After troubleshooting, re-enter the anti-theft code, and re-initialize the navigation system, then enter the
audio presets.
 Check for aftermarket accessories that use the same power circuit. A feedback can cause this problem.
1. Remove the key from the ignition.
Go to step 2.
The system is OK at this time.
2. The vehicle may have been used as a demonstration vehicle at an event like an auto
show. In these events, power is often jumpered to
the navigation system so that the ignition key is not
needed in the vehicle. At the end of the show, the
jumper wire may not have been removed. Check
the navigation unit connector A (24P) for a non-
factory jumper wire in series with the factory cable.
Remove the jumper wire, and re-test. Return
the jumper wire to Tech Line.
Go to step 3.
3. Check if the audio unit works.
Troubleshoot the ACC circuit for a short to
power with another circuit.
Replace the navigation unit (see page 23-355). NOTE:
 Check the vehicle battery condition first.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode and use
Version (see page 23-316).
 Check for connectors for poor connections loose terminals.
 Before troubleshooting, make sure you have anti- theft codes for the navigation system.
 After troubleshooting, enter the anti-theft codes for the navigation system.
 Make sure that the correct navigation DVD color and version are installed.
 Inspect the navigation DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
1. Make sure the anti-theft code for the navigation system is entered.
2. Go into the Diagnostic Menu, and use the Navi System Link test (see page 23-297).
Do the troubleshooting for the voice
guidance cannot be heard (see page 23-341).
Go to step 3.
3. Substitute a known-good navigation unit (see page 23-355), and recheck.
Replace the navigation unit (see page 23-355).

Navigation Through Menus
23-362HandsFreeLink System
General Troubleshooting Information (cont’d)
Many issues result from the client not using the system
properly. Make sure the client is using the HFL buttons
and not the navigation buttons. When the HFL TALK
button is pressed, the client hears one audible tone.
When the HFL BACK button is pressed, the client hears
two audible tones. Make sure to press the HFL BACK
button to exit the HFL main menu after completing a
call and before giving any navigation commands.
The HFL system may experience a number recognition
issue, such as when a client says a set of numbers in a
group unrecognized by the system. The HFL system
understands phone numbers in specific blocks of 1, 3, 4,
7, and 10 numbers. For example, the system
understands:
1234567890
123-456-7890
1-2-3-4-5-6-7-8-9-0
The system may become confused if numbers are
stated in other blocks, as following: 1234-567-890
12-34-56-78-90
12345-67890
123-4567-890 To skip a voice prompt, press and release the HFL TALK
button while the HFL system is speaking. The system
beings listening for your next voice command.
To go back a step in a voice command sequence, press
and release the HFL BLACK button, or press the HFL
TALK button and say ‘‘Go back.’’ If you
don’t say
anything while the HFL system is listening for your
voice command, it times out and stops voice
recognition. The next time you press and release the
HFL TALK button, the HFL system begins listening from
the point it timed out.
If you’ve finished or want to stop a voice command
sequence at any time, press and release the HFL BACK
button, or press and release the HFL TALK button, wait
for the beep, and say ‘‘Cancel.’’ The next time you press
and release the HFL TALK button, the HFL system
begins from its main menu. To avoid keeping the audio
system muted, press and release the HFL BACK button
when you are finished.
NOTE: You can say multiple commands in one
sequence, like ‘‘Phone setup-pair’’ after pressing the
HFL TALK button.

Dropped Calls
23-365
Clients may perceive dropped calls as being an HFL
system fault, but most dropped calls are from cell
phone and cell phone carrier issues. The HFL system
does not directly handle the cell phone signal. It allows
the cell phone to transmit the cell phone audio over the
vehicle’s audio system.
Before troubleshooting for dropped calls, confirm the
cell phone settings: Disable Audio Answer. If Auto Answer is enabled, incoming calls are routed to voice mail.
 Disable Always Ask/Trust, Authorize Device, or similar setting, If these settings are enabled, each
time the HFL system attempts to link to the phone, the
phone will ask if you want to connect. If you do not
allow the connection, the HFL will not operate. The
phone must be set to N ever Ask, Authorize Device,
etc. (based on the phone manufacturer and carrier)
for permission. Refer to the cell phone owner’s
manual for more information.
 Disable Flip Open to Answer. If this setting is enabled, the phone must remain open in the vehicle. If it is
closed, the incoming calls are routed to voice mail. Always confirm with the client if the number of dropped
calls is higher while using the HFL system as opposed
to using the cell phone only. Clients often confuse
problems with their phone or carrier as a problem with
the HFL system. The HFL system cannot control or
determine:
 Cellular connection quality.
 Signal strength.
 Cellular coverage.
 Ambient weather conditions that affect cellular signals.
When a client complains about dropped calls, ask
questions about when or where the calls are dropped,
such as:  Do you drive the same route on a regular basis?
 Does the call drop in the same location?
 Where do you keep your cell phone?
 Have you compared the number of dropped calls using the HFL versus making calls from the handset?
 Does your phone have an antenna that needs to be extended?
