DVD HANDLING AND CLEANING

To avoid damaging or leaving fingerprints on the DVD, always handle it by the edges and place it in a jewel
case whenever it is outside the navigation unit. Deep scratches or fingerprints on the back of the DVD can
cause intermittent rebooting or other system errors.

Smudges and fingerprints can be carefully removed using a mild cleaner and tissues designed to clean
eyeglasses. To clean a DVD, use a clean soft cloth. Very gently wipe across the DVD from the center to the
outside edge, never in a circular motion.

Do not place stabilizer rings or labels on the DVD.

model year, each color DVD may under go a half a dozen "software
only" version up grades 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 clients future free updates. There are no free
programs for updating the navigation DVD. Update DVDs are generally
available for purchase each fall. The on-line DVD order site provides
information when an update for a particular color DVD is available.



Damaged discs are not warrantable.

EARLIEST DVD VERSION APPLICATION FOR EACH MODEL

Each navigation system DVD contains a map/POI (point of interest) database and the navigation system
software for each model that it supports. Inserting an older DVD can cause problems since it lacks the
software to provide the specific features needed for that model. Unfortunately, the navigation software does
not detect or warn you that the version is outdated, and it may even appear to operate.

Typical warning symptoms that an outdated DVD is being used include:



The Acura model navigation screen may display a Honda logo while booting up.



A newly introduced model feature or current accessory may not display properly, and Extension will
display instead.



The current street (the street being driven on) may not appear properly at the bottom of the map screen
display when the vehicle is driven on a main road.

HOW TO IDENTIFY NAVIGATION DVD VERSIONS, AND HOW TO INSPECT A DVD FOR
DAMAGE

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 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.



Anytime you call Tech Line regarding a navigation system issue.



To answer client inquires concerning update or coverage issue.



Check the underside of the DVD for signs of mishandling. Deep scratches, swirl marks, or

NOTE:

Replacing a DVD just because the version number is higher is not always
warranted. A higher software version does not necessarily mean it contains
newer software for your model. The DVD contains software for all models
that use the same color DVD, and a revised number may or may not have
software fixes or upgrades for the model in question.

NOTE:

Extension may be displayed when using Music Link, but should never
be displayed when XM is selected.

NOTE:

If necessary, compare the operation to the navigation system of the
same model and year vehicle that has a current DVD.

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 Acura Disc
Fulfillment Center (see ORDERING A DVD).

fingerprints can cause random lock-ups, reboots, and DVD read or format errors.



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 it causes system malfunctions that mimic a hardware problem. This result in the
client driving away 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 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 Acura Disc Fulfillment Center (see ORDERING A
DVD).

HOW TO ANSWER CLIENT QUESTIONS ABOUT NAVIGATION COVERAGE

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.

Is my address covered by the navigation system?

Using a current production vehicle (of the same model), try entering 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 lager metropolitan city name. If the address is shown in a later year
vehicle, but not your client's vehicle, you might want to recommend that your client purchase an update.

Is my city covered by the navigation system?

For general questions about whether a city is covered, view the map coverage link on the DVD order site.
On the site, you enter a year and model, and 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 client's road or address is in the
system. Verifying on an actual production vehicle is always the best guarantee that your information is
accurate.

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.

NOTE:

If it is determined that the navigation unit is defective (through the
appropriate service manual troubleshooting procedures) and the DVD will
not eject, order a replacement navigation unit, and also order a DVD from the
Acura Disc Fulfillment Center.

The gas station on my corner is now a restaurant. Why is it still incorrect in the navigation system?

For POI-related client questions, explain that businesses are constantly moving, and there can be a
considerable lag in updating the millions 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 on-line DVD order site, by clicking on the FAQs link (see ORDERING A DVD).

PRECAUTION ON CLIENT "SNEAK PREVIEWS"

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 new 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.

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, by chance, a newer version is located accidentally, 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. Refer to the iN for
applicable patches that may need reinstalling.
