Honda CR-V: General Troubleshooting Information

General Operation

Refer to the navigation system manual, for the navigation system operating procedures.

Anti-theft Feature

The navigation system has a coded theft protection circuit. Make sure you have the customer's anti-theft security code before;

After service, reconnect power to the navigation unit, and turn the ignition switch ON (II). Enter the 4-digit anti-theft security codes, then select "Done".

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

Symptom Diagnosis

Certain circumstances and system limitations will result in occasional vehicle positioning errors. Some customers 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 customers about symptoms of 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:

Global Positioning System (GPS) Limitations

The GPS cannot detect the vehicle's position during the following conditions:

The accuracy of GPS is reduced during these instances:

Muting Logic

Whenever the navigation system is giving guidance, the front speakers are muted. When the voice control system is being used, all of the speakers are muted.

LCD Unit Limitations

Symptom Duplication

Service Precautions

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 Security Code

The navigation system has a coded theft protection circuit. Make sure you have the customer's anti-theft security codes number before;

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

GPS initialization

Depending on the length of time the battery or the navigation unit 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.

After 30 minutes with this screen displayed, turn off the engine, then restart the vehicle. If you now see the Disclaimer screen, the GPS initialization is complete.

NOTE:

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.honda.com "ORDER NAVIGATION DVD" link.

Both methods require a credit card. The DVD for this model has an turquoise (blue/green) label, and cannot be ordered through the parts system. The following DVDs will not work in this navigation system:

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

NOTE: Updating is optional, and there is no program to provide free DVDs containing yearly mapping updates.
