light ACURA CSX 2006 Service Repair Manual

How to Identify Navigation DVD Versions,
and How to Inspect A DVD for Damage
23-271
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: Check any official Acura service website for more service information about the navigation DVDs.
 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: Client’s may obtain DVDs from sources
outside the normal ordering process. If you
determine this is the case, recommend that your
customer purchase the appropriate DVD from the
Acura Disc Fulfillment 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 The DVD version provided to the client is out-of date or incompatible with a particular model.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
Acura Disc Fulfillment Center.
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.

Overview
23-279
System Description
The navigation system is a highly sophisticated, hybrid locating system.
The navigation unit uses global positioning system (GPS) satellite signals, internal yaw and vehicle speed inputs, and
a map database to show where the vehicle is and to help guide you to a desired destination.
The navigation unit’s GPS receiver receives signals from the GPS, a network of 24 satellites in orbit ar ound the earth.
By receiving signals from several of these satellites, the navigation system can determine the latitude, l ongitude, and
elevation of the vehicle.
Signals from the system’s yaw rate sensor (inside the navigation unit) detects turns, and the ECM/PCM vehicle speed
pulse (VSP) and reverse signal enable the system to keep track of the vehicle’s speed and direction of travel. The
advantage of this hybrid system is that the system can track your position if either the GPS signal or the vehicle speed
signal is missing. For instance, when in a tunnel (no GPS), the speed signal is used to update your position on the map.
Alternately, while the vehicle is being transported on a ferry, GPS signals can show the vehicle position on the map as
it crosses the water.
The navigation system uses the location, direction, and speed information to display the appropriate map and
calculate a route to the destination entered. As you drive to a destination, the system provides both visual and audio
guidance. Audio guidance is sent to the audio unit, and an RGB graphics color signal is sent to the navigation display.
This navigation system also has voice recognition that allows voice control of most of the navigation, and audio
functions. The voice control switches (navigation TALK and navigation BACK buttons on the steering wheel) activate
the voice control system. The microphone on the ce iling receives your voice commands. For more information on this
feature, consult the navigation owner’s guide.
The illumination signal is used by the navigation unit to automatically switch the display mode between the Night and
Day display modes. When the headlights are on, the dash brightness control setting full brightness overrides the Night
display mode, and allows a daytime navigation display with the lights on.
When the navigation system is giving voice guidance commands, the front speakers are muted. When the voice
control system is being used (navigation TALK button pressed), all of the speakers are muted.
The internal GA-Net II bus passes information back and forth between the navigation display, the navigation unit, and
the audio system components. The information passed on this bus are touch button commands, audio muting signal,
audio (radio and XM), and any open in these bus lines can affect the navigation system or other audio accessory
operation.
The clock on the navigation display is set and maintained by the navigation unit. The time is automatically adjusted for
daylight savings, and time zone changes while driving. The time can be adjusted in setup.
Additional information is available about the navigation components following the System Diagram. A glossary of
terms that are used throughout this section follows the detailed information.
The Navigation System Manual in the glove box covers all of the system functions and settings. Use this as a resource
when evaluating a customer concern.
The Comm.Bus connects the HFL and the navigation unit.
If a POI phone number is available, the navigation unit sends the phone number (on the calcurate route to screen) to
the HandsFreeLink control unit for dialing.

Overview of navigation display
The illumination input from the gauge brightness
control provides back lighting for the buttons
surrounding the screen.
These screens allow you to troubleshoot the navigation
display. Select the item you want to troubleshoot, and
follow the diagnostic instructions. This screen verifies that the display unit is receiving the
video (R, G, B and Composite sync) signals properly.
The three primary colors should all appear without
distortion. The combination of all three should produce
a central white section. If the picture has lines in it, or
scrolls horizontally or vertically, and any of the colors
are missing, troubleshoot for a composite sync and
color signal problem (see page 23-339).
This screen diagnoses problems with contrast. You
should be able to see the changes from bar to bar
across the scale. It is normal for the two bars on either
side to appear the same. If you can’t see changes from
bar to bar, replace the navigation unit.

This diagnostic screen checks for pixels that may be
stuck on. The entire display must be black. If pixels are
stuck on, replace the navigation unit.
The panel touch sensing system consists of a touch
sensitive resistive membrane covering the display.
Contrary to other systems using infrared beams, the
screen has to be physically touched to make it work.
The display has the capability of 479 touch locations
(left to right), and 233 touch locations (top to bottom).
The upper left hand corner is position (0, 0) and the
lower right hand corner is (479, 233) as displayed.
Touching anywhere on the screen displays the
coordinate of the location, and a icon appears where
you touched the screen. If any area of the screen either
doesn’t respond, or responds at some other location
when touched, then replace the navigation unit.
NOTE: Unlike earlier screens that used infrared sensors,
direct sunlight does not affect this test. The display screen uses a touch sensitive membrane.
This means that every location of the entire surface of
the display is touch sensitive. This diagnostic allows
alignment of these touch locations with the location of
the buttons images on the screen.
Normally this should n
ever need adjustment, and is
used only to adjust the touch locations for parallax (the
touch locations appear different when viewed at an
angle). However, if an adjustment is necessary, follow
this procedure:
 The screen consists of the button icons. Touch the center of the five buttons on order 1 5.
 To store any change you make, touch the Set button.
 Use the Return key to exit the diagnostic.
