Navigation System
System Description (cont'd)
Overview
The Acura Navigation System is a highly-sophisticated, hybrid locating system that uses satellites and a map database to
show you where you are and to help guide you to a desired destination.
The navigation system receives signals from the Global Positioning System (GPS), a network of 24 satellites in orbit
around the earth. By receiving signals from serveral of these satellites, the navigation system can determine the latitude,
longitude, and elevation of the vehicle. In addition, signals from the system's yaw rate sensor and the PCM (vehicle
speed pulse) enable the system to keep track of the vehicle's direction and speed of travel.
This hybrid system has advantages over a system that is either entirely self-contained or one that relies totally on the
GPS. For example, the self-contained portion of the system can keep track of vehicle position even when satellite signals
cannot be received. When the navigation system is on, the GPS can keep track of the vehicle position even when the vehi-
cle is transported by ferry.
The navigation system applies all this location, direction, and speed information to the maps and calculates a route to the
destination entered. As you drive to that destination, the system provides both visual and audio guidance.
This navigation system also has voice recognition that allows voice control of most of the navigation functions. The TALK
and BACK buttons on the steering wheel activate the voice control.
The illumination signal is used for two purposes. The display unit uses the signal to light up the hard buttons surrounding
the display. In addition the signal is used by the navigation unit to automatically switch from the "Day" to "Night" display
mode when the headlights are on. This automatic switching occurs only if the "Display" setting in setup screen 1 is set to
"AUTO". If the headlights are on and the customer has the dash light brightness control to "full bright," then this overrides
the "Night" mode.
The use of the audio speakers follows a hierarchy. The highest priority is the OnStar voice, followed by the navigation voice,
and finally the radio/CD. The audio unit enforces this hierarchy. The GA-Net bus is used to pass commands to mute the speak-
ers, and to disable the voice control system. Prior systems used dedicated wires to accomplish this function.
• If On-Star is in use, the audio unit passes a command on the GA-Net bus to the navigation unit to disable the voice control
system. The navigation unit then ignores the voice control switch, and temporarily ceases voice route guidance prompts.
• When the navigation system issues route guidance, the navigation unit uses the GA-Net bus to tell the audio unit to mute just
the front speakers. When the voice control system is being used (the TALK/BACK buttons), the navigation unit uses the GA-
Net bus to tell the audio unit to mute all speakers.ProCarManuals.com
Navigation System
System Description (cont'd)
Audio Unit
The audio unit receives the audio driving instructions from the navigation unit and transmits the instructions through the
front speakers even when the audio system is in use.
Display Unit
The display unit uses liquid crystal display (LCD). The LCD is a 7-inch-diagonal, thin film transistor (TFT), stripe type with
280,800 picture elements. The color film and fluorescent light are laid out on the back of the liquid crystal film. The touch
sensor on the front of the LCD is an infrared type with 20 vertical and 9 horizontal infrared rays to produce 180 sensing
points. The display unit transmits the signal from each operation key and the touch switches to the navigation unit.
Infrared rays
Microphone (Mic)
Receives voice commands and transmits them to the navigation unit for interpretation.
Talk Button (Voice Control Switch)
Activates the voice control system in the navigation unit to accept voice commands.
Back Button (Voice Control Switch)
Returns the display to the previous screen.ProCarManuals.com

Definition
Off road tracking dots that can be followed on the map to retrace your route back to a
mapped (digitized) road. This function can be turned on/off in Setup screen 1.
Central Processing Unit. The main device within the navigation unit that coordinates the
rest of the electronic functions.
This consists of the Map data, and the POI (Points Of Interest) data stored on the DVD.
Detailed Coverage Area. Main metropolitan areas in the Lower 48 states, and Canada are
mapped to this level. See the Navigation Owner's manual for a list of these areas.
Diagnostic Trouble Codes. Use the HDS tablet to obtain, and troubleshoot the cause of
these codes.
The use of the speed signal, and yaw rate sensor to position the vehicle on the map even
when the GPS signal is obscured by tall buildings, or while driving in a tunnel.
A road that appears on the navigation screen. The road name will appear at the bottom of
the navigation screen. If the user drives "off road" the navigation system will display
"Not on a digitized road", and if 1/2 mile, then "breadcrumbs" will appear.
Screen containing cautionary information. It is meant to read carefully and acknowledged
by the customer when using the navigation system.
Digital Versatile Disk. The navigation program and database resides on this disk. See the
Navigation Owner's Manual for information on how to order a replacement or update
DVD.
Engine Control Module. Typically referred to as the PCM
Frequency Asked Question. See the Navigation Owner's Manual for a list of the customer
FAQs, and troubleshooting information
Proprietary communication bus. This serial bus connects the audio unit, navigation unit,
display unit, and XM receiver. Signals passed on this bus include audio muting requests,
navigation and display unit buttons, control commands, and XM control sequences.
Global Positioning System. A network of 24 satellites in orbit around the earth. The navi-
gation system can simultaneously receive signals from up to 12 satellites to accurately
positioning the vehicle on the map.
Honda Diagnostic System. A hand held tablet PC for use in diagnosing vehicle problems.
This device can be used to obtain DTC codes for diagnosis of navigation system CAN
related problems.
Head Unit. The navigation system display unit assembly in the dash.
This refers to the period needed to re-acquire the GPS satellite orbital information when-
ever the navigation system power has been disconnected. This can take from 10 to 45
minutes.
Liquid Crystal Display (the navigation screen)
The received GPS information allows the navigation system to position the vehicle on the
map. Map matching has occurred if the map screen is displaying the current street name
in the bottom-shaded area.
Abbreviation for the microphone used for receiving voice commands. It is located near
the map light in the ceiling
