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

Vehicle position icon constantly leaves road, moves erratically, or is very far from actual position

NOTE:
- 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.
- Always make sure that the correct DVD color and version are installed.
- Inspect the DVD for dirt or damage.
- Check any official Honda service website for more service information about the navigation system.

1. Check the GPS icon on the navigation picture.

Is the GPS icon white?

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 normal. Check to see if the problem occurs in the same place. If it does, the problem could be in the database. Go to step 4.

NO - If the problem is the yaw rate sensor, replace the navigation unit. If the problem is the vehicle speed pulse, check for an open in the wire between the navigation unit and the PCM. If the wire is OK, troubleshoot the vehicle speed signal circuits.

4. Substitute a known-good navigation unit, and check to see if the problem occurs in the same place.

Does the problem occur in the same place?

YES - The problem is in the database. Report the problem according to the Navigation System Manual under Reporting Errors.

NO - Replace the original navigation unit.
