Vehicle Position Icon Constantly Leaves Road, Moves Erratically, Or Is Very Far From Actual Position

NOTE:
- Always make sure that the correct DVD color and version are installed.
- Check any official Honda service website for more service information about the navigation system.
- Check for aftermarket accessories.
- Check the vehicle battery condition first.
- Check the connectors for poor connections or loose terminals.
- This is not the same condition as when driving off-road (or on a fire or logging road). This condition is caused by a loss of map matching from a bad sensor input. Check for aftermarket or other objects that can block the GPS signal. Always do the Map matching before proceeding with the troubleshooting.

1. Check the GPS icon on the navigation picture.

Is the GPS icon on the map screen?

YES - Do the troubleshooting for GPS icon is white or not shown.

NO - Go to step 2.

2. Go into the Diagnostic Menu, and use the Yaw Rate test to check the yaw rate sensor.
3. Go into the Diagnostic Menu, and use the Car Status test to check the vehicle speed pulse.

Are the yaw rate sensor and vehicle speed pulse OK?

YES - The problem may be a normal characteristic. Check to see if the problem occurs in the same place. If it does, the problem could be in the database. Compare to a known-good vehicle under the same conditions. If you can duplicate the problem, report it. Refer to the Customer Assistance section of the navigation system manual, "Reporting Errors".

NO - If the problem is the yaw rate sensor, replace the navigation unit. If the problem is the vehicle speed pulse, troubleshoot the vehicle speed signal circuit.
