23-90Navigation System
General Troubleshooting Information
Refer to the Navigation System manual for the
navigation system operating procedures.
The navigation system has a coded theft protection
circuit. Be sure you have the client’s anti-theft security
code before;
 Disconnecting the battery
 Disconnecting the navigation unit A (17P) and C (12P) connector
 Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box
After service, reconnect power to the navigation unit,
and turn the ignition switch ON (II). Enter the 4-digit
anti-theft security codes, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the Navi ECU diagnostic screen (see page 23-139).
Alternatively, you can find the serial number from the
navigation unit in the dash.
When replacing the navigation unit, be sure to give the
client the new anti-theft security code.
Certain circumstances and system limitations can result
in occasional vehicle positioning errors. Some clients
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing clients
about symptoms of the navigation system. The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause some discrepancies between
the vehicle’s actual position and the indicated vehicle
position (GPS vehicle position).
The following circumstances may cause vehicle
positioning errors:
 Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
 Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface.
– Driving with snow chains mounted.
– Abnormal tire pressure.
– Incorrect tire size.
– Frequent lane changes across a wide highway.
– Continuous driving on a straight or gently curving highway.
 Tolerances in the system and map inaccuracies will sometimes limit how precisely the vehicle position is
indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible).
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage.
– Driving on a road with a series of sharp hair-pin turns.
– Driving near a gradual highway exit or transition.
– Driving on one of two close parallel roads.
– Making many 90 degree turns.
– The direction to destination icon or the destination icon shown or the map may be up to several
hundred feet away from the actual location.

The system is acquiring its GPS signal.
This could take up to 10 minutes. Engine must be running
 Vehicle must be parked outside, away from buildings
 Do not move the vehicle at this time
***Wait***
Any time the navigation system loses power, you need
to enter the 4-digit anti-theft code on the navigation
system display. The 4-digit code is located on a small
card that was given to the customer. Enter the 4-digit
code, then select Done.
If the navigation system anti-theft code is missing, use
the interactive Network (iN) to look it up. You will need
the serial number for the navigation unit to do this.
You can view the serial number by entering the
diagnostic mode. Select Unit Check from the main
menu, then the Navi ECU diagnostic screen. This gives
you the serial number without removing the navigation
unit.
The iN may display more than one code for a given
serial number. This is because serial numbers are not
unique. You may have to try more than one 4-digit code.
If no code is shown, or if the code(s) given do not work
in the navigation unit, contact the Automobile Warranty
department. If the code 0000 works, replace the
navigation unit.
When replacing the navigation unit, make sure you give
the customer the new anti-theft security code. NOTE: You must park the vehicle outside with a clear
view of the southern sky.
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. 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 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.

How to Identify Navigation DVD Versions,
and How to Inspect A DVD for Damage
23-96Navigation System
General Troubleshooting Information (cont’d)
To determine the navigation version on a particular
model, start the engine, then locate the navigation unit.
Open the DVD door, and push the eject button to eject
the DVD. Hold the DVD by the edges, and check for
these items:
 The DVD label color.
 Read the DVD version on the label, and note it on the repair order. The version number is near the bottom
of the label text (for example, ver: 4.23A). You will
need this version number:
– To verify that the DVD version is appropriate for the vehicle. Check any official Honda service website
for more service information.
– Any time you call Tech Line regarding a navigation system issue.
– To answer client inquires concerning update or coverage issue.
NOTE: Clients may obtain DVDs from sources
outside the normal ordering process. If you
determine this is the case, recommend that your
client purchase the appropriate DVD from the
Honda Disc Fulf illment Center (see ORDERING A
DVD).
– Check the underside of the DVD for signs of mishandling. Deep scratches, or random scratches,
light swirl marks, or fingerprints can cause random
lock-ups, reboots, erratic voice response, erratic
positioning errors, and DVD read or format errors.
NOTE: A damaged DVD is not covered under
warranty unless the disc is damaged by the
navigation unit. Damage by the navigation unit
typically appears as circular scratches caused by
something rubbing against the DVD as it spins. The
damage may appear as arcs or complete circles on
the DVD reading surface.
– Verify that the underside of the DVD is silver, and not a copy with a blue color. Copies will not work
properly and can cause other symptoms that mimic
hardware problems.  Incorrectly colored DVDs being put into navigation
vehicles. This causes the system to either display
error messages, or causes system malfunctions that
mimic a hardware problem. This results in the client
leaving with a malfunctioning navigation system.
 The DVD version provided to the client is out-of date or incompatible with a particular model. This
inconveniences your client by delaying the repair, or
by causing additional (and unnecessary) returns to
your dealership.
 The client experiences bugs or other issues that have already been resolved in later versions currently
available at the fulfillment desk.
If the DVD is defective, or has any of the issues
mentioned above, return the vehicle to your client and
recommend that they order the proper DVD from the
Honda Disc Fulf illment Center (see ORDERING A DVD).
NOTE: Navigation DVDs do not come with replacement
navigation units. If you are replacing a navigation unit
because it is defective (following appropriate service
manual troubleshooting), and the DVD does not eject,
order a DVD. See Obtaining a navigation DVD.

 After troubleshooting, enter the navigation system anti-theft code.
 Full brightness on the instrument panel brightness control with the head lights turned on causes the
system to stay in the day mode, even when the lights
are on.
1. Make sure the instrument panel brightness control is not on full brightness. Turn the headlights on and
adjust the dash brightness to the middle range.
2. Change the day/night mode under Set-up to AUTO, and recheck.
The system is OK at this time.
Go to step 3.
3. Go into the Diagnostic Menu and use the Car Status test to check for an ILL signal (see page 23-141).
Replace the navigation unit (see page 23-155).
Check the ILL circuit between the
navigation unit and the No. 14 (7.5 A) fuse in the
under-dash fuse/relay box. NOTE:

 ILL-Illumination Indication
(Navigation unit connector A (17P) terminal No. 10)
a) OFF (0) when parking lights, or headlights are off
b) ON (1) when parking lights, or headlights are on
The navigation unit uses the signal to determine
whether to put the navigation screen into the Day or
Night brightness mode. (Setup screen 1)
 Display-this displays the current position of the display
a) (Close) when the display is closed
b) (Open) when the display is open
The navigation unit has a micro switch to detect this. If
open is indicated when the display is closed, replace
the navigation unit. This screen shows the current status of GPS reception.
The circular diagram shows the current location of the
GPS satellites (yellow balls) 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 satellites shown on the diagram
correspond to the PRN number in the GPS Details
screen. There are always 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.
 Metallic window tinting on the front or side window or after-market electronic accessories mounted near
the navigation unit, GPS antenna, or navigation
display can interfere with GPS acquisition.
 The Number of Satellites box shows the number of acquired satellites (maximum of 12). It should contain
4 or more icons. If not, troubleshoot for GPS icon is
white or not shown (see page 23-122).
 The Current Position shows latitude, longitude, and elevation (in meters). If there are less than 4 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 client in Setup function Adjust
Time Zone/Clock.
