Navigation system is unable acquire a
 Move vehicle to another location
 Turn the ignition switch off
 Disconnect the battery for 30
minutes to clear the GPS receiver’s
memory
 Reconnect the battery and follow
the screen prompts proper GPS signal.
If the navigation system finds the satellites properly,
this box clears, and changes to the Disclaimer screen. If
within 10 minutes the system fails to locate a sufficient
number of satellites to locate your position, the
following screen appears.
After 30 minutes with this screen displayed, turn off the
engine, then restart the vehicle. If the Disclaimer screen
appears, the GPS initialization is complete.
NOTE:
 The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes.
 If the system is still unable to acquire a signal, follow the instructions on the screen. If this screen appears
again, go to troubleshooting for the GPS icon is white
or not shown (see page 23-122).
 To bypass the GPS acquire screens, press and hold the Menu, and Zoom out keys at the same time.
Touch the Return button on the screen to exit the
diagnostic mode. This allows you to continue
troubleshooting while in the shop.
This part of the initialization matches the GPS
coordinates with a road on the map screen. To do this
part of the procedure, make sure that the navigation
system displays a map, and drive the vehicle on a
mapped 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. If the navigation DVD is lost or damaged, or you need a
yearly
updated DVD, you have 2 ways to purchase one.
You can either call 888-291-4675, or order on-line at
www.hondanavi.com.
Both methods require a credit card. The DVD cannot be
ordered through the parts system. The following DVDs
will not work in this navigation system:
 Earlier model navigation DVDs (black, orange, or older vesions with a white label)
 Map software programs manufactured by other companies
 DVD movies, or DVDs containing audio recordings
 Copies of an original Navigation DVD
Update DVDs are available for purchase usually in the
fall of each year. They may contain the following:  Enhanced maps and points of interest (POI) coverage
 Fixes for minor software bugs
 Additional features
NOTE:  Map matching must be done any time the DVD is removed or replaced.
 Always order navigation DVDs on an as-needed basis. During a typical model year, each color DVD may
undergo a half a dozen software only version
upgrades to fix minor issues on some or all models
the DVD supports. This is normal. Usually only the
letter at the end of the version number changes,
while the database (maps and POIs) remain
unchanged.
 Never promise your customers future free updates.
There are no free programs for updating the
navigation DVD. Update DVDs are generally available
for purchase each fall. The on-time DVD order site
provides information when an update for a particular
color DVD is available, damaged discs are not
warrantable.

NOTE: Check the vehicle battery condition first.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
 Check the connector for poor connection or loose terminals.
 Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code.
 After troubleshooting, enter the navigation system anti-theft code.
Before assuming that a voice complaint is hardware
related, ensure that the voice control system is being
operated correctly.  Make sure you are on the correct screen when trying to issue a voice command. For instance, the
command ‘‘Find the nearest Italian Restaurant’’ only
works on a Map screen (See the Navigation System
Manual for a complete list of allowed voice
commands for the information being displayed.).
 Close the windows, moonroof, and doors.
 Set the fan speed to low (1 or 2).
 Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the
ceiling.
 Pause after pressing the navigation TALK button, then give a voice command clearly in a natural
speaking voice. If the system cannot recognize your
command, speak louder.
 If the microphone picks up voices other than yours, the system may not interpret your voice commands
correctly.
 If you speak a command with something in your mouth, or your voice is too husky, the system may
misunderstand your command.
 Compare the system operation with a known-good vehicle. Have more than one person test the system
operation. If the known-good vehicle performs the
same, it is a characteristic of the system. 1. Turn the ignition switch to ON (II).
2. Go into the Diagnostic Menu and use the Mic Level
test under Functional Setup (see page 23-147) to
check the operation of the navigation TALK and
navigation BACK buttons.
Go to step 10.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Do the voice control switch test (see page 23-156).
Go to step 5.
Replace the voice control switch.
5. Disconnect the cable reel 20P connector and navigation unit connector D (5P).
6. Check for continuity between body ground and navigation unit connector D (5P) terminal No. 4.
Repair short to body ground in the wire
between the navigation unit and the voice control
switch, or replace the cable reel.
Go to step 7.
