How to Troubleshoot the Navigation System

Is my city covered by the navigation system?

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

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 online navigation DVD order site, by clicking on the FAQs link.

How do I find the local address of a business that is part of a national chain (for example, Starbucks)?

There are three ways to find the local address to businesses:

- If you know the phone number of the business, select Phone Number and enter the 10 digit phone number (area code plus seven digit number).
- Select Category, then Restaurant. Enter the keyword Star. The resulting list includes all restaurants that have the letters Star anywhere in the name.
- Select Name and enter Starbucks. For more common business names, like McDonalds, you may have to search through a list that includes other businesses like McDonalds Welding, McDonalds Automotive, etc.

Why are some features different or missing compared to my previous Honda vehicle?

Hardware and software continually go through updates and improvements. Features may change or disappear over time based on the navigation system development.

Precaution on Customer Navigation DVD Sneak Previews

Your customer might request a look (or sneak preview) at features in the latest navigation software. You should never preview a navigation DVD in a customer's vehicle. Inserting a new navigation DVD installs the latest software from the navigation DVD into the memory of the customer's navigation system. When the original navigation DVD is reinstalled, the newer software remains in memory and is often incompatible with the customer's original navigation DVD Map and POI database.

If your customer wishes to see the latest navigation coverage or software features, demonstrate it on an in-stock vehicle that already has the latest navigation DVD version.

If a newer version is loaded, either by the dealer or the customer, the only remedy is to enter the navigation diagnostic mode's Version screen and do a forced download. Check any official Honda service website for more information about what patches may need reinstalling.

How to Check Error History (Navigation DTCs)

NOTE: The navigation DTCs cannot be retrieved with the HDS.

The Error History feature is to record intermittent navigation issues that occur while using the system by setting navigation DTCs. Sometimes the customer complaint cannot be duplicated. The error history may record the information needed to diagnose the problem. To check the error history:

1. Start the engine.

2. Press and hold the MAP/GUIDE, MENU, and CANCEL buttons for 3 seconds.

3. When the Select Diagnosis Items menu is displayed, select Self-Diagnosis Mode.






4. When the audio-navigation unit has hard error codes, the Error History icon appears yellow when the Self-Diagnosis mode (System links) screen is displayed. When no hard errors are stored, the icon appears gray. To view the errors with their navigation DTC codes, select the error history icon.






5. Select Hard Error

NOTE: Soft errors are for factory use only.






Hardware Error History

6. The Hard Error screen displays the following information for each error:

- The navigation DTC for the error.
- A brief description of the navigation DTC.
- The date and time when the error occurred.

NOTE:

- To see additional errors, use the interface dial to select UP or DOWN icons (A).
- Write down the DTCs, then select Clear to delete the error history. The Save feature is for factory use only.





- Use the DTC Symptom Troubleshooting table to troubleshoot the error.

- Clear the navigation DTCs.

- Select Return to exit the error history.

Software Error (Soft Error) History

Software errors are not available. They are for factory use only.

How to Clear Error History

NOTE: It is recommended that you write down the stored DTCs before clearing them.

1. Do the steps in How to check Error History.

2. Select Clear in the error menu.

NOTE:

- By selecting Clear, all software and hardware errors stored in history are erased at the same time.
- Save is for factory use only.

3. After selecting Clear, then selecting Yes, both Hard Error history and Soft Error history are cleared at the same time.
