How to Troubleshoot the Navigation System
Muting Logic
Whenever the navigation system is giving guidance, the front speakers are muted. When the navigation voice control system is being used, all of the speakers are muted.
If HandsFreeLink is in use, the voice control system is unavailable and a message appears on screen.
LCD (Liquid Crystal Display) 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 and a navigation DTC may be set).
- 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 be noticeable. Clean the screen with a soft, damp cloth. You may use a mild cleaner intended for eye glasses or computer screens. To avoid scratching the panel, do not rub too hard or use abrasive cleaners or shop towels.
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 self-diagnostic procedures and the appropriate troubleshooting procedures.
- When the symptom does not reappear or only reappears intermittently, ask the customer about the conditions when the symptom occurred.
- Always ask the customer to demonstrate the problem.
- Ask the customer if they remember the time and date when they had the issue. You may be able to find the DTC stored in the hard error history.
- 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 customer 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.
NOTICE
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 creating symptoms or causing effects unrelated to the original problem.
Service Precautions
- If you need to replace the audio-navigation unit, you can back-up the navigation data and transfer it to a new audio-navigation unit. See save users memory.
- 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.
- Before disconnecting the battery, make sure you have the anti-theft codes for the navigation system. Also obtain any PGM-FI or transmission DTCs and freeze frame date (which will be lost when the ECM/PCM loses power).
- After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10 to 45 minutes.
- Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
- Before returning the vehicle to the customer, enter the anti-theft codes for the audio system and the navigation system.
System Initialization
If the navigation system loses power (like the battery was disconnected), the navigation system requires initialization. Once completed, the system is 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 the Security Code
Any time the navigation system loses power, you need to enter the 4-digit anti-theft code on the navigation system display. This 4-digit code is located on a small code card that was given to the customer. Enter the 4-digit code, then select Done.
If the navigation system anti-theft code is missing, get the serial number from the audio-navigation unit and use the interactive Network (iN) to look it up. You do not need to remove the audio-navigation unit. See Anti-Theft Feature.
When replacing the audio-navigation unit, make sure you give the customer the new anti-theft security code.
GPS Initialization
NOTE: You must park the vehicle outside with a clear view of the southern sky.
Depending on the length of time the battery was disconnected, your system may require GPS initialization. If it does, the following screen appears:
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 within 10 minutes the system fails to locate a sufficient number of satellites to locate your position, the following screen appears.
If this screen appears, turn off the engine, then restart the vehicle and move it to a different location. If the disclaimer screen appears, 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 GPS icon is white or not shown troubleshooting.
- Skip to a CSF screen by pressing the MENU and the ZOOM OUT buttons at the same time and you can move to a System Links screen.
Lever-Locked Connector
Disconnecting
To disconnect the connector, pull the lever (A) while pushing the lock tab (B) down, then pull out the connector (C).
Connecting
To connect the connector, push the connector into the connector sleeve (A). As the connector is pressed in, the lever (B) moves to the locked position.
Map Matching
This part of the initialization matches the GPS coordinates with a road on the map screen. To do this part of the procedure, make sure 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 two ways to purchase one. You can either call 888-291-4675, or order on-line at www.hondanavi.com.
Both methods require a credit card. The navigation DVD for this model has a turquoise label, and cannot be ordered through the parts system. The following DVDs will not work in this navigation system:
- Earlier model navigation DVDs (black, orange, white, and older versions with a turquoise label). Refer to any official Honda service website for more information about navigation DVD colors and versions.
- Map software programs manufactured by other companies
- DVD movies, or DVDs containing audio recordings
Update navigation 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 navigation DVD is removed or replaced.
- Always order navigation DVDs on an as-needed basis. During a typical model year, each color navigation DVD may undergo a half a dozen software only version upgrades to fix minor issues on some or all models the navigation 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 customer future free updates. There are no free programs for updating the navigation DVD. Update navigation DVDs are generally available for purchase each fall. The online navigation DVD order site provides information when an update for a particular color navigation DVD is available.
- Damaged discs are not covered by warranty unless they have been damaged by the navigation system.
DVD Handling and Cleaning
To avoid damaging or leaving fingerprints on the navigation DVD, always handle it by the edges and place it in a jewel case whenever it is outside the audio-navigation unit. Deep scratches or fingerprints on the back of the navigation 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 navigation DVD, use a clean soft cloth. Very gently wipe across the navigation DVD from the center to the outside edge, never in a circular motion.
Do not place stabilizer rings or labels on the navigation DVD.
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 navigation 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. Refer to any official Honda service website for more information about navigation DVD colors and versions.
NOTE: Replacing a navigation 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 navigation DVD contains software for all models that use the same color navigation 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 navigation DVD is being used include:
- The Honda model navigation screen may display an Acura logo while booting up.
- A newly introduced model feature or current accessory may not display properly, and Extension may display instead.
- The system locks up when entering an address or POI.
- The current street (the street being driven on) does 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 navigation DVD.
