This screen is for factory use only. It allows adjustment
of the GPS time. This display updates in real time.
 GPS Time is the time as received from the GPS satellites. It is in Greenwich Mean Time (GMT).
 Date, Hour, Minute, and Set should not be used.
This screen allows the navigation system to drive a
route, when the vehicle is stationary. Typical
applications include auto shows, and other events.
This feature allows a visitor to enter a destination, and
see the system drive to the destination. No speed signal
is needed.  To initiate the mode, select ON.
 Changing the speed rate in ms (millisec onds) is
optional, and represents the time between updates of
the VP (vehicle position) movement.
– When you increase the rate, the VP slows down because it is updated (moved) at a slower rate.
– When you decrease the rate, VP is faster because it is updated (moved) more frequently.
– 1500 ms is VP at its slowest in demo mode.
– 150 ms is VP at its fastest in demo mode (Default).
 At key off, the setting automatically returns to the default of Off. This diagnostic screen 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 ceiling. It is directional, and works best if the
voice is coming from the drivers 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 on the screen does not briefly turn green,
then check the wiring from the navigation TALK
button to the navigation unit.
 If there is no Mic Level movement when you speak, then you should check the wire running from the
microphone to the navigation unit.
 If the mic level bar is full or almost full wit hout you
speaking or other back ground noise, replace the
microphone and recheck.

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.
