23-266Navigation System
General Troubleshooting Information
Refer to the navigation system manual for the
navigation system operating procedures.
The navigation system and audio unit have a coded
theft protection circuit. Make sure you have the anti-
theft security code before:
 Disconnecting the battery.
 Disconnecting the navigation unit connector A (24P) and C (8P).
 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 to ON (II). Enter the 4-digit
anti-theft security code, 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 ECU Info diagnostic screens (see page 23-305).
Alternatively, you can find the serial number on the
underside label which is located on the navigation unit
in the trunk.
When replacing the navigation unit, be sure to give the
customer the new anti-theft security code.
Certain circumstances and system limitations will result
in occasional vehicle positioning errors. Some client’s
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 client’s
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 discrepancies between the
vehicle’s actual position and the indicated vehicle’s
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
– Very bumpy roads
 Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle’s 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 GPS cannot detect the vehicle’s position or
elevation during the following instances:  For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
 When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside
parking structures or large trucks.
 When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the
vehicle. The GPS antenna requires a clear
unobstructed view of the sky.
 When there is no satellite signal output (signal output is sometimes stopped for sate llite servicing).
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.

Muting Logic
LCD Unit LimitationsSymptom Duplication
23-267
The accuracy of the GPS is reduced during these
instances:
 Metallic window tinting above the GPS antenna.
 When only three or less satellite signals are received (Four satellite signals are required for accurate
positioning).
 When driving near high tension power lines.
 When the satellite control centers are experiencing problems.
Whenever the navigation system is giving guidance,
the front speakers are muted. When the voice control
system is being used, all of the speakers are muted. If
the HandsFreeLink is in use, the voice control system is
unavailable and a message appears onscreen.
NOTE: The screen is not touch sensitive. Use the
interface dial and buttons to select items on the screen.  In cold temperatures, the display may stay dark for the first 2 or 3 minutes until it warms up.
 When the display is too hot because of direct summer sunlight, it will remain dark until the temperature
drops (you may see an error message displayed
stating this fact).
 When the humidity is high and the interior temperature is low, the display may appear cloudy.
The display will clear up after some use.
 Fingerprints on the screen may be noticeable. Clean the screen with a soft, damp cloth. You may use a
mild cleaner intended for eye glasses or computer
screens. To avoid scratching the panel, do not rub too
hard or use abrasive cleaners or shop towels.  When the symptom can be duplicated, verify that it is
not a characteristic of the system. Review the
navigation system manual and compare it to a
known-good vehicle (with the same software and
database), under the same conditions. If the
symptom is not the same as the known-good vehicle,
follow the self-diagnostic procedures and the
appropriate troubleshooting procedures.
 When the symptom does not reappear or only reappears intermittently, ask the client about the
conditions when the symptom occurred.
– Always ask the client to demonstrate the problem.
– Trytoestablishpossibleusererrorora misunderstanding of the system.
– Try to establish if outside interference may have been the cause.
– Try to duplicate the symptom under the same conditions the client experienced.
– Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to
duplicate.
– Inspect the vehicle for after-market electronic devices (vehicle locators, amps, radar detectors,
etc.) that may be hidden.
When troubleshooting navigation system problems,
ensure that the known-good vehicle is the same
software version year and model as the vehicle being
serviced. Mixing incompatible navigation DVDs or
other system components can delay the
troubleshooting process by creating symptoms or
issues causing effects unrelated to the original problem.

How to Answer Client Questions About
Navigation CoverageHow do I find the local address of a business
that is part of a national chain (for example,
Starbucks)?
Precaution on Client ‘‘Sneak Previews’’
Is my address covered by the navigation system?
Is my city covered by the navigation system?
The gas station on my corner is now a restaurant. Why
is it still incorrect in the navigation system?
23-272Navigation System
General Troubleshooting Information (cont’d)
Some clients may ask questions regarding a city,
address, or POI (point of interest) covered by the
navigation system. It is better to verify a coverage
question on an actual vehicle than to disappoint your
client by promising coverage that may be incomplete or
missing in their area. The following suggestions can be
used to answer coverage inquiries from your client.
Using a current production vehicle (of the same model),
try and enter the client’s address (street first) to see if
their area is covered. Always enter the street first,
because sometimes their city may be included in a
neighboring township, or under some larger
metropolitan city name. If the address is shown in a
later year vehicle, but not your client’s vehicle, you
might recommend that your client purchase an update.
For general questions about whether a city is covered,
view the map coverage link on the DVD order site. On
the site, select a year, and select a model, then click on
the Coverage link. You then select a state or province,
and the cities are listed. Of course, this does not
guarantee that the customer’s road or address is in the
system. Verifying on an actual production vehicle is
always the best guarantee that your information is
accurate.
For POI-related client questions, explain that
businesses are constantly moving, and there can be a
considerable lag in updating the m
illions of POIs in the
system. The database is updated annually, and the best
way to the verify whether the POI is accurate is verify
the inquiry on a current production vehicle.
Answers to these and other questions regarding
coverage can be found in these locations:
 In the Frequently Asked Questions section of the navigation system manual.
 At the online DVD order site, by clicking on the FAQs link. There are three ways to find the local address to
businesses:
 If you know the phone number of the business, select Phone Number and enter the 10 digit phone number
(area code plus seven digit number).
 Select Category, then Restaurant. Enter the keyword Star. The resulting list includes all restaurants that
have the letters Star anywhere in the name.
 Select Name and enter Starbucks. For more common business names, like McDonalds, you may have to
search through a list that includes other businesses
like McDonalds Welding, McDonalds Automotive, etc.
Your client might request a look (or sneak preview) at
features in the latest navigation software. You should
never preview a navigation DVD in a client’s vehicle.
Inserting a newer DVD installs the latest software from
the DVD into the memory of the client’s navigation
system. When the original DVD is reinstalled, the newer
software remains in memory and is often incompatible
with the client’s original DVD Map and POI database, or
software.
If your client wishes to see the latest navigation
coverage or software features, demonstrate it on an in-
stock vehicle that already has the latest DVD version.
If a newer version is loaded either by the dealer or the
client, the only remedy is to enter the navigation
diagnostic mode’s Version screen and do a forced
download. Check any official Honda service website for
more information about what patches may need
reinstalling.
