GENERAL OPERATION

Refer to the Navigation System Manual for the navigation system operating procedures.

ANTI-THEFT FEATURE

The navigation system and audio unit have a coded theft protection circuit. Make sure you have the antitheft security codes before:





Disconnecting the battery.

Disconnecting the navigation unit 8P connector.



Removing the No. 7 (10A) fuse from the driver's under-dash fuse/relay box.

After service, reconnect power to the navigation unit, and turn the ignition switch 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 the Navi ECU diagnostic screen (see UNIT CHECK ). Also, you can find the serial number on the navigation unit that is stored in the trunk. The serial number is on a label on the bottom of the unit.

When replacing the navigation unit, be sure to give the client the new anti-theft security code.

SYMPTOM DIAGNOSIS

Certain circumstances and system limitations will result in occasional vehicle positioning errors. Some clients 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 clients about symptoms with the navigation system.

SELF-INERTIAL NAVIGATION LIMITATIONS

The limitations of the self-inertial portion of the navigation system (the yaw rate sensor and the vehicle speed signal) can cause some discrepancies between the vehicle's actual position and the indicated vehicle 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.



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 position is indicated. Examples of this include: me

Friday, June 05, 2009 3:28:14 PM Page 2 © 2005 Mitchell Repair Information Company, LLC.

2007 Acura RL




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

GLOBAL POSITIONING SYSTEM (GPS) LIMITATIONS

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 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 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.

The accuracy of GPS is reduced during these instances:



Metallic window tinting above the GPS antenna





When only three satellite signals can be received (Four satellite signals are required for accurate positioning).

When the satellite control centers are experiencing problems.





When driving near high tension power lines.

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

Whenever the navigation system is giving guidance, all of the 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.

LCD UNIT LIMITATIONS



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 sometimes be noticeable because of the panel's low-reflection coating. me


2007 Acura RL


Clean the screen with a soft, damp cloth. You may use a mild cleaner intended for eye glasses or computer screens.

SYMPTOM DUPLICATION



When the symptom can be duplicated, verify that it is not a characteristic of the system. Review the navigation 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 selfdiagnostic 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.



Try to establish possible user error or 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.

NOTE: When interchanging navigation DVD/parts during diagnosis.

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 causing side effects unrelated to the original problem.

SERVICE PRECAUTIONS



If the navigation unit needs to be replaced, inform the client that personal information in the navigation system will be lost. If possible, have the client record their personal information before the unit is replaced.





On '07 and later models you can back-up the navigation data and transfer it to a new navigation unit.

See save USERS MEMORY , audio system and navigation system.

Before disconnecting the battery, make sure you have the anti-theft codes for the audio and the navigation system, and write down the audio presets. Also obtain any PGM-FI or transmission DTCs and freeze frame data (which will be lost when the PCM loses power).





When the battery is disconnected, the internal GPS clock is reset to "0:00". The clock will reset to the correct time after the system finishes GPS initialization.

After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10 to 45 minutes.

Verify map matching.



Before returning the vehicle, enter the audio system and navigation system anti-theft security code, then enter the audio presets. me


2007 Acura RL


Adjust the setup clock settings (time zone and daylight savings) in the navigation system.

SYSTEM INITIALIZATION

If for any reason, you lose power to the navigation system (like the battery was disconnected), the navigation system will require initialization. Once completed, your system will be ready to use.

This initialization requires the following:





Entering the 4-digit anti-theft security code to "unlock" the system

GPS initialization (may not be needed depending of the length of time the system was without power)



Map matching to align the GPS to a location on the map

ENTERING SECURITY CODE

Any time power is disconnected from the navigation unit, the 4-digit anti-theft code must be entered on the navigation system display. This 4-digit code can be found on a small code card that was given to the client.

Enter the 4-digit code, then select "Done".

If the navigation system anti-theft code cannot found, use the interactive Network (iN) to look it up. You will need the serial number for the navigation unit to do this. You can view the serial number by entering the diagnostic mode. Select Unit Check from the main menu, then the Navi ECU diagnostic screen. This allows you to get the serial number without removing the navigation unit.

The N may display more than one code for a given serial number. This is because serial numbers are not unique. You may have to try more than one 4-digit code. If no code is shown, or if the code(s) given do not work in the navigation unit, contact the Automobile Warranty department. If the code "0000" works, then replace the navigation unit.

When replacing the navigation unit or audio unit, be sure to give the client the new anti-theft security code.

GPS INITIALIZATION

Depending on the length of time the battery was disconnected, your system may require GPS initialization.

If it does, the following screen appears:

***Wait***

The system is acquiring its GPS signal. This could take up to 10 minutes.





Engine must be running

Vehicle must be parked outside, away from buildings



Do not move the vehicle at this time

If this procedure is not necessary, the system proceeds directly to the Disclaimer screen. During initialization, the system searches for all available GPS satellites, and obtains their orbital information.

During this procedure, the vehicle should be out in the open with a clear view of the sky.

If the navigation system finds the satellites properly, this box clears, and changes to the Disclaimer screen. If me


2007 Acura RL

2005-08 ACCESSORIES AND EQUIPMENT Navigation System - RL within 10 minutes the system fails to locate a sufficient number of satellites to locate your position, the following screen appears.

Navigation system is unable acquire a proper GPS signal.



Move vehicle to another location





Turn the ignition switch off

Disconnect the battery for 30 minutes to clear the GPS receiver's memory



Reconnect the battery and follow the screen prompts

If this is displayed, turn off the engine, then restart the vehicle. If you now see the Disclaimer screen, the

GPS initialization is complete.

NOTE:





The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes.

If the system is still unable to acquire a signal, follow the instructions on the screen. If this screen appears again, go to troubleshooting for the GPS ICON IS WHITE OR NOT SHOWN .

MAP MATCHING

This part of the initialization matches the GPS coordinates with a road on the map screen. To perform this part of the procedure, ensure that the navigation system is displaying a map, and drive the vehicle on a mapped road shown on the map screen). Do not enter a destination at this time. When the name of the current road you are driving on, appears at the bottom of the screen, the entire procedure is complete. Your system is now ready to use.

OBTAINING A NAVIGATION DVD

If the Navigation DVD is lost or damaged, or you need a yearly updated DVD, you have 2 ways to purchase one. You can either call (888) 549-3798, or order on-line at www.acura.com.

Both methods require a credit card. The DVD for this model has a white label, and cannot be ordered through the parts system. The following DVDs will not work in this navigation system:





Earlier model navigation DVDs (black label)

Map software programs manufactured by other companies



DVD movies, or DVDs containing audio recordings

Update DVDs are available for purchase usually in the fall of each year. They may contain the following:



Enhanced maps and points of interest (POI) coverage





Fixes for minor software bugs

Additional features

NOTE:





Map matching must be done any time the DVD is removed or replaced.

Always order navigation DVDs on an as-needed basis. During a typical me


2007 Acura RL




 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.

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.

Fig. 2: Identifying DVD Handling


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.

Fig. 3: Identifying DVD Cleaning


Do not place stabilizer rings or labels on the DVD.

me


2007 Acura RL


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.

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.

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.

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



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.

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

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.

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).



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


2007 Acura RL

2005-08 ACCESSORIES AND EQUIPMENT Navigation System - RL fingerprints can cause random lock-ups, reboots, 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 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).

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.

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. me


2007 Acura RL


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.

SYSTEM DESCRIPTION

OVERVIEW

The navigation system is a highly-sophisticated, hybrid locating system that uses satellites and a map database to show where the vehicle is 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 several 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 vehicle is transported by ferry.

The navigation system applies all location, direction, and speed information to 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 Navigation TALK and BACK buttons on the steering wheel activate the voice control. The voice control also allows control of the audio and climate functions.

The illumination signal (headlights ON) is used by the navigation unit to automatically switch the display between "Night" and "Day" brightness modes when display is set to Auto. When the instrument panel is set to night and the brightness control is set to full brightness (hold both "+" and "-" key at the same time), the navigation system stays in the day mode, even with the headlights on.

The GA-NET II bus passes information back and forth between the display panel control unit, the navigation unit and the audio system, The information passed on this bus are audio and climate control settings directed by the navigation unit.

The "Comm. Bus" connects the HFL, XM (AcuraLink), and navigation units. This bus supports these functions:





The navigation control unit receives traffic and message information from the AcuraLink Control unit.

The navigation control unit sends a POI phone number ("Calculate route to" screen) to the HFL for dialing.





If vehicle problems are detected, and the client's cellular contract includes data service, then the HFL can send vehicle data to the HFL unit for transmitting back to the AcuraLink servers.

The AcuraLink server can pass additional problem details back through the HFL, to the AcuraLink

Control unit, and finally to the navigation unit for display. me

GA-Net Bus Configuration

The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.

These commands include navigation audio/XM selections by voice, and XM station and music title names.

Because the entire bus is interconnected between components, an open or short in the GA-Net bus harness may cause any or all of these functions to become inoperative.

Vehicle Speed Pulse

The vehicle speed pulse is sent by the PCM. The PCM receives a signal from the countershaft speed sensor, then processes the signal and transmits it to the speedometer and other systems.

Charge Signal, Navigation Unit Cooling Fan Operation and Trip Computer

The PCM sends a charge signal to the navigation unit via F-CAN. A thermister inside the navigation unit monitors the units internal temperature. This information combined with a charge signal determines the control units internal cooling fan operation. The navigation system displays trip computer information that is calculated by the gauge assembly.

Fig. 8: Charge Signal, Navigation Unit Cooling Fan Operation And Trip Computer Diagram


Yaw Rate-Lateral Acceleration Sensor

The yaw rate-lateral acceleration sensor (located in the navigation unit) detects the direction change (angular speed) of the vehicle. The sensor is an oscillation gyro built into the navigation unit.

Sensor Element Structure

The sensor element is shaped like a tuning fork, and it consists of the piezoelectric parts, the metal block, and the support pin. There are four piezoelectric parts: one to drive the oscillators, one to monitor and maintain the oscillation at a regular frequency, and two to detect angular velocity. The two oscillators, which have a 90-degree twist in the center, are connected at the bottom by the metal block and supported by the support pin. A detection piezoelectric part is attached to the top of each oscillator. The driving piezoelectric part is attached to the bottom of one oscillator, and the monitoring piezoelectric part is attached to the bottom of the other oscillator.

Oscillation Gyro Principles

The piezoelectric parts have "electric/mechanical transfer characteristics. "They bend vertically when voltage is applied to both sides of the parts, and voltage is generated between both sides of the piezoelectric parts when they are bent by an external force. The oscillation gyro functions by utilizing this characteristic me


2007 Acura RL

2005-08 ACCESSORIES AND EQUIPMENT Navigation System - RL of the piezoelectric parts and "Coriolis force. "(Coriolis force deflects moving objects as a result of the earth's rotation.) In the oscillation gyro, this force moves the sensor element when angular velocity is applied.

Operation

1. The driving piezoelectric part oscillates the oscillator by repeatedly bending and returning when an

AC voltage of 6 kHz is applied to the part. The monitoring-side oscillator resonates because it is connected to the driving-side oscillator by the metal block.

2. The monitoring piezoelectric part bends in proportion to the oscillation and outputs voltage (the monitor signal). The navigation unit control circuit controls the drive signal to stabilize the monitor signal.

3. When the vehicle is stopped, the detecting piezoelectric parts oscillate right and left with the oscillators, but no signal is output because the parts are not bent (no angular force).

4. When the vehicle turns to the right, the sensor element moves in a circular motion with the right oscillator bending forward and the left oscillator bending rearward. The amount of forward/rearward bend varies according to the angular velocity of the vehicle.

5. The detecting piezoelectric parts output voltage (the yaw rate signal) according to the amount of bend.

The amount of vehicle direction change is determined by measuring this voltage.

Global Positioning System (GPS)

The global positioning system (GPS) enables the navigation system to determine the current position of the vehicle by using the signals transmitted from the satellites in orbit around the earth. The satellites transmit the satellite identification signal, orbit information, transmission time signal, and other information. When the GPS receiver receives a signal from four or more satellites simultaneously, it calculates the current position of the vehicle based on the distance to each satellite and the satellite's position in its respective orbit.

Position detection Image with GPS satellite me

Fig. 10: Identifying Global Positioning System (GPS)


Precision of GPS

The precision of the GPS varies according to the number of satellites from which signals are received and the view of the sky. The precision is indicated by the color and shape of the GPS icon shown on the display.

DESCRIPTION

The GPS can't be utilized due to a faulty

GPS receiver, open in the wire, or other fault or interference.

GPS function is normal. The satellite signals received by the GPS are too few to detect the vehicle position.

The longitude and latitude of the vehicle position can be detected. (Less precise than detection in three dimensions)

The longitude, latitude and the altitude of the vehicle position can be detected. (More precise than detection in two dimensions)

GPS Antenna

The GPS antenna amplifies and transmits the signals received from the satellites to the GPS receiver.

GPS Receiver and Clock

The GPS receiver is built into the navigation unit. It calculates the vehicle position by receiving the signal from the GPS antenna. The current time, vehicle position, and signal reception condition is transmitted from the GPS receiver to the navigation control unit to adjust vehicle position.

Navigation Unit

The navigation unit calculates the vehicle position and guides you to the destination. The unit performs map matching correction, GPS correction, and distance tuning. It also controls the menu functions and the DVDme


2007 Acura RL


ROM drive, and interprets voice commands. With control of all these items, the navigation unit makes the navigation picture signal, then it transmits the signal to the display panel control unit and audio driving instructions to the audio unit.

Calculation of Vehicle Position

The navigation unit calculates the vehicle position (the driving direction and the current position) by receiving the directional change signals from the yaw rate sensor and the travel distance signals from vehicle speed pulse (VSP) signal of the PCM.

Map Matching Tuning

The map matching occurs when you drive the vehicle along a mapped road until the road name appears of the bottom of the screen. The map data transmitted from the DVD-ROM is checked against the vehicle position data, and the vehicle position is indicated on the nearest road. Map matching tuning does not occur when the vehicle travels on a road not shown on the map, or when the vehicle position is far away from a road on the map.

GPS Tuning

The GPS tuning is accomplished by indicating the vehicle position as the GPS's vehicle position. The navigation unit compares its calculated vehicle position data with the GPS vehicle position data. If there is large difference between the two, the indicated vehicle position is adjusted to the GPS vehicle position.

Distance Tuning

The distance tuning reduces the difference between the travel distance signal from the VSP and the distance data on the map. The navigation unit compares its calculated vehicle position data with the GPS vehicle position data. The navigation unit then decreases the tuning value when the vehicle position is always ahead of the GPS vehicle position, and it increases the tuning value when the vehicle position is always behind the

GPS vehicle position.

Route Guidance

The navigation unit can calculate different routes to a selected destination. You have five options:





Direct Route-Calculate a route that is the most direct.

Easy Route calculate a route that minimizes the number of turns needed.





Minimize Freeways-Calculate a route that avoids freeway travel. If that is not possible, keep the amount of freeway travel to a minimum.

Minimize Toll Roads-Calculate a route that avoids, or minimizes travel on toll roads.



Maximize Freeways-Calculate a route that uses freeways as much as possible.

Audio Guidance

The navigation unit transmits audio driving instructions before entering an intersection or passing a junction.

The audio instructions come through the audio unit to the front speakers.

NOTE: The front speakers are muted whenever the navigation system is giving guidance commands, and all of the speakers are muted when the voice me

Off Road Tracking (breadcrumbs)

Off road tracking dots that can be followed on the map to retrace your route back to a mapped (digitized) road.

Clock and Time Zone

The clock set up allows you to set daylight setting time, auto time zone and time adjustment.

Muting Signal Logic

The audio muting logic is controlled by the audio unit. The audio unit determines what audio source has priority to use the speakers.

The priority of the audio sources is as follows:

On-Star ('05-06 models) has the highest priority, followed by HFL, AcuraLink, navigation, and finally the radio/CD-DVD player. The priority is passed by On-Star ('05-06 models), HFL, and AcuraLink to the audio unit by dedicated mute wires. The navigation mute signal is passed to the audio unit on the GA-Net bus.

The navigation unit temporarily disables the voice control buttons, but allows guidance to be heard. In addition, the audio unit suppresses the output from the radio, XM unit, disc player, or other audio accessories.

When the navigation system sends out a voice route guidance command, the audio front center speaker is muted, and the navigation voice is heard in the front speakers.

When the navigation voice control system is in use, all of the speakers are muted, and the navigation voice prompts are heard from the front speakers.

CAR STATUS

Use this screen to confirm that the navigation unit is properly receiving input signals. Signals equal to (0) are OFF, and signals equal to (Dare ON. If the value on the display does not match the actual vehicle status, then check the wire carrying the signal.



VSP-Vehicle Speed Pulse from PCM (Pin 6 of C-connector) a. OFF (0) when vehicle is not moving b. ON (1) when vehicle is moving

The VSP comes from the PCM as a dedicated signal. Internally, the navigation unit compares the actual VP on the map against street data to adjust the pulse to speed scaling factor. As this scaling factor becomes more accurate, the "Level" gradually increases from 0 to 10 (see the TIRE CALIBRATE diagnostic screen).



BACK-Reverse indication from taillight relay (Pin 5 of C-connector) a. OFF (0) when the shift lever is in any position other than reverse b. ON (1) when the shift lever is in reverse

The Back signal is used by the navigation unit to allow the map screen to show the VP moving backwards when in reverse. This signal is needed because the Speed Pulse has no direction indication.

2007 Acura RL

2005-08 ACCESSORIES AND EQUIPMENT Navigation System - RL a. OFF (0) if illumination cancel is not selected b. ON (1) if illumination cancel is activated

The illumination cancel function is activated by increasing the dash brightness to "MAX" using the "+" button. The CAN bus passes this information from the gauge control module to the navigation control unit.

NOTE: This setting is unaffected by the "display mode" hard button located below and to the left of the interface dial.



ILL-Illumination Indication

This signal is used by the navigation unit to determine whether to put the navigation screen into the Day or

Night brightness mode (Setup screen 1).



DVD Lid-senses if DVD door is open a. (Close) when door is closed b. (Open) when door is open

The navigation unit has a micro switch to detect this. If open is indicated when the door is closed, replace the navigation unit.

F-CAN SYSTEM LINK

F-CAN (Fast Controller Area Network) passes information between processors on the network. For example, the F-CAN network is used to pass charging system signals between the PCM and the navigation unit for the trip computer cooling fan function. The F-CAN network uses a communication protocol that transmits data at 500 Kbps.

COVERAGE AREA

This screen allows the dealer to select the area that applies to their location. The choice is US (continental) or Hawaii. The default is "US." Select the choice (the system may reboot), exit the diagnostic mode, and restart the vehicle.

NOTE: This function is designed to operate only when the vehicle is physically located in the coverage area you select.

Fig. 72: Screen Display - Coverage Area


GPS INFORMATION

This screen shows the current status of GPS reception. The circular diagram shows the current location of the GPS satellites (yellow numbers) as they would appear in the sky. The outer circle represents the horizon

(0 degrees elevation). The middle and inner circles represents 30 and 60 degrees respectively. The very center of the diagram (90 degrees elevation) is directly overhead. Nearby obstructions, like tall buildings, will block satellites in that direction. That is why it is necessary to be in an open area to effectively troubleshoot GPS reception issues. The satellite numbers shown on the diagram correspond to the "PRN" number in the "GPS Details" screen. There are always at least 24 "active" GPS satellites in orbit. Because satellites fail, and have to be removed from service, spares are always parked in orbit, ready to be activated.

This is why the PRN (satellite ID number) can be greater than 24.

NOTE: To use this screen for troubleshooting, the vehicle should be out side away from buildings, tall trees, and high-tension wires for at least 10 minutes with the engine running.



The "Number of Satellites" box shows the number of acquired satellites (maximum of 12). It should contain four or more icons. If not troubleshoot for "GPS icon is white or not shown" (see GPS ICON

IS WHITE OR NOT SHOWN ).





The "Current Position" shows latitude, longitude, and elevation (in feet). If there are less than four satellites, the elevation can be grossly inaccurate.

YAW RATE

This diagnostic checks the yaw rate sensor in the control unit. This device detects when the vehicle turns, and repositions the vehicle position icon on the map screen. For more detailed information, see the yaw rate sensor theory of operation under "System Description" (see YAW RATE-LATERAL ACCELERATION

SENSOR ).





"Sensor" indicates the voltage output from the yaw rate sensor. It should indicate about 2.500 volts when stopped.

"Offset" is the reference voltage or standard within the yaw rate sensor. It also should indicate about

2.500 volts when stopped.



A "sensor" output voltage LOWER than the "Offset" voltage indicates that the vehicle is turning to the right.

A "sensor" output voltage HIGHER than the "Offset" voltage indicates that the vehicle is turning to the left.

 The yaw rate offset, and sensor should both indicate about 2.500 volts when stopped. If either reads zero, or 5.000 volts, replace the navigation unit.



The yaw rate offset and sensor should be within +/-0.01 V of each other when stopped. The sensor value should change relative to the offset as the car is turned while driving. If not, replace the navigation unit.

"Sensitivity study" represents the status of the internal tuning function. At initialization, this value starts at 6 and increases to # 10 as the internal correction values become more accurate.

The settings "CCW Cal Factor," "CW Cal Factor," and "Set" are for factory use only. THIS SHOULD

NEVER BE ADJUSTED.



For detailed analysis of the yaw rate select "tuning."

Fig. 75: Screen Display - Yaw Rate


YAW RATE TUNING

This diagnostic allows you to graphically display problems with the yaw rate sensor.





The "ANG-Disp" value accumulates any differences between the "offset," and "sensor" voltages (see

Yaw Rate diagnostic, refer to YAW RATE ) . When the sensor is working properly, the random changes in these two voltages generally cancels out, so the value is 0. However if one voltage is consistently higher than the other, then the "ANG-Disp" value accumulates the constant change.

The "Reset" button temporarily clears the angular accumulation (ANG-Disp), and clears the display dots.



Do not touch the "CCW," "CW," or "Set" buttons. These are used for factory setup only.

Two tests are explained below. For gross problems with the sensor, the stationary test usually confirms whether the sensor is defective. For yaw rate issues related to driving, perform the road test described below.

1. Stationary test: If the "VP" icon spins in place and the "ANG-Disp" value slowly increases or decreases in value, the yaw rate sensor is defective. Replace the navigation control unit.

2. Road test: Drive the vehicle on a very straight road. Enter the diagnostic mode, select "Yaw rate," and touch the "Tuning" button. While driving down a straight road, the white "dots" should trace a straight line across the screen. However, if you are driving on a straight road, and you notice the dots constantly dropping down or heading up as you drive, the navigation control unit's yaw sensor is defective. You can touch "Reset" to clear "ANG-Disp," and dotted lines.

If either test above fails, please enter "Yaw rate sensor defective" for the problem description, on the

"Navigation core return form." me


2007 Acura RL


Fig. 76: Screen Display - Yaw Rate Tuning


TIRE CALIBRATE

As the vehicle moves, the navigation system receives speed pulses from the PCM. These pulses are converted using a conversion factor to a mph speed that moves the vehicle position (VP) on the map. The navigation system has an internal tuning function that generates and refines this factor based on actual driving. The "Study" indicates the status of the tuning. At navigation initialization, it begins at 0, and increases to 10 as the navigation system is used.



The "Auto Tuning" is factory set to "ON," and should remain on.





The "Study" indicates the tuning status. If it is less than 10, the unit is still calibrating.

The "Tire-Cal. Tuning" and Set should not be used. It is for factory use only.

Solar Angle

This screen graphically displays the sun's position as determined by the GPS. The navigation system uses the sun's angle, along with the sunlight sensor to control the driver/passenger A/C air flow. The heat that the

A/C unit removes varies, depending on the angle of the sun entering the vehicle. This screen is for factory use only, and should not be adjusted.





The screen shows a circular diagram of the sky oriented in the direction that the vehicle is pointing.

During daylight hours a red dot is shown, representing the direction and elevation of the sun. The outer circle represents the horizon (0 degrees elevation). The middle circle is 30 degrees, the center circle is 60 degrees, and the very center is directly overhead (90 degrees).

The "manual tuning" button should always be "OFF."





The "Angle" is the angle that the sun (shown with red "dot") is above the horizon.

The "vehicle" value represents the angle, clockwise from North, to the direction that the vehicle position (VP) icon is pointing (always points straight up).





The "direction" value is the angle, measured clockwise from the VP (straight up) to the suns position.

The reliability ranges from 1 to 3, and represents the accuracy of the Vehicle Position relative to the sun.

Select "YES" on the "Import Confirmation" screen.

Import moves the two files stored by the Export process from the PC card to the new navi ECU. When the transfer is finished (a few seconds) the system will automatically reboot. After the system reboots, remove the PC card from the PC slot.

If the Import button is grayed out, follow the troubleshooting in the FAQs below. The client's files can only be transferred to a new core if the "Model" and the "Program Flash" shown on the "Version" screen are the same. So files cannot be transferred from Civic to Accord, or from a Civic with version 1.07.00 to a Civic with version 1.32.00.

PC Card FAQs

PC CARD FAQS CHART

Question Answer

Where do we buy the flash do we ask for?

You need a "PCMCIA type II" adaptor and a flash memory chip (see below for memory chip types). They can be purchased at a computer, memory or adaptors, and what or office supply store. The card will have the same size and shape as the PC card in the HDS. Adaptors that accept multiple flash types are not recommended.

What memory flash chips will

The flash memory devices that have been tested include Compact work with what adaptors?

Flash (CF), and ATA style (like the card in the HDS). Other card types and flash memory chips may work, but have not been tested.

What capacity card do 1 need for this function?

A memory chip with capacity of 64 MB to 2 GB will work. The two files moved to the card during "export" are less than a Megabyte in size. An adaptor and flash memory can be obtained for less than 50 dollars.

Should the dealer have a dedicated card for the Export and Import navigation function?

What device can 1 use to maintain the card, and delete files?

Yes, treat the card as a dedicated "special tool" that should be used anytime your '07 or later client needs their navi personal files transferred to a new ECU core.

Any computer store sells USB style PC card readers that accept the card, and allow you to perform file maintenance on your card. Most laptops will also accept the card.

Can we move the client's data to different models (like moving Civic navi data to a

Pilot)?

No, the files are model specific and will only load into a navi ECU with the same part number.

Can we move the client's data to the same vehicle with a different software version

(Like moving version 4.51)?

The client's files can only be transferred to a new core, if the "Model" and the "Program Flash" shown on the "Version" screen are the same.

Files cannot be transferred from Civic to Civic Hybrid (different model code), or '07 Civic to '08 Civic (different versions).

The "Export" button is

"grayed out" Why?

2007 Acura RL




A PC card with it's media memory chip is not inserted.

The "Import" button is

"grayed out". Why is this?



The model code of the files stored during export do not match the model code of the new navi ECU.



The version of the files from the original navi ECU are not the same as the version in the new ECU.

Will other files on the card like images or music files prevent the Export/Import function from working?

No, the system simply adds two small files that are recognized by the new core when performing the Import function. However, if the card is full, the "Export" function won't work correctly.

Do I have to delete the files on the card after each transfer of the client's data?

After the transfer of client data to the new core, the files remain on the card. Since this is confidential information, we recommend that you delete these files after each use. Please note that each time you export navi files of the same model and version, the files are overwritten.

Over time the card will accumulate two files for each version of the 8 or so Honda navi models.

What format should be used if It is unlikely that the card will ever need formatting, however the FAT the card needs reformatting?



The card may not be fully inserted into the slot. Eject the card, and inspect for warping or damage to the edge connector. Never use excessive force to insert a card. This can result in damage to the pins in the rear of the slot.

The card may not contain files that are recognized by the new core. Navi data can only be transferred between cores with the same "Model code", and with the same navi "Program flash" version.





The flash memory chip type may not be accepted by the system.

Only Compact Flash and ATA cards have been tested.

The card's PCMCIA adaptor may be preventing a known good card from playing. Avoid multi slot type PCMCIA adaptors that accept several different flash memory types.
