Vehicle icon wanders across the map when driving (does not follow a displayed road) or map vehicle ICON spins

NOTE:
  • Check the vehicle battery condition first (see BATTERY TEST ).
  • 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 (see MAP MATCHING ) before proceeding with the troubleshooting.
  • Verify that the correct navigation unit is installed for this model. Go into the System Diagnostic Mode (see SYSTEM DIAGNOSTIC MODE ), and use Version (see VERSION ).
  • Make sure that the correct navigation DVD color and version are installed.
  • Check for aftermarket metallic window tinting.
  • Inspect the DVD for dirt or damage.
  • Check any official Honda service website for more service information about the navigation system.
  • Before troubleshooting, make sure you have anti-theft codes for the audio system and the navigation system.
  • After troubleshooting, enter the anti-theft codes for the audio system and the navigation system.
  1. Check the GPS icon on the navigation screen.

    Is the GPS icon white or missing? 

    YES  -Do the GPS icon is white or not shown troubleshooting (see GPS ICON IS WHITE OR NOT SHOWN ). ■

    NO  -Go to step 2.

  2. Go into the System Diagnostic Mode (see SYSTEM DIAGNOSTIC MODE ), and use the Yaw Rate (see YAW RATE ) to check the yaw rate sensor.

    Is the yaw rate sensor OK? 

    YES  -Go to step 3.

    NO  -Replace the navigation unit (see NAVIGATION UNIT REMOVAL/INSTALLATION ). ■

  3. Go into the System Diagnostic Mode (see SYSTEM DIAGNOSTIC MODE ) and use the Car Status (see CAR STATUS ) to check the vehicle speed pulse (VSP) and the BACK signals.

    Are the vehicle speed pulse and the BACK signals OK? 

    YES  -The symptom may be a characteristic of the system. Check to see if the symptom occurs in the same place in a known-good vehicle. If it does, the problem could be in the database. Go to step 4.

    NO  -

    • If the problem is the vehicle speed pulse, troubleshoot the vehicle speed signal circuit. Check the BLU/WHT wire for an open or short. If OK, update the PCM (see PCM UPDATE ), if it does not have the latest software or substitute a known-good PCM (see PCM REPLACEMENT ).
    • If the BACK signal is indicated ON (I), when in any shift lever position other than reverse, troubleshoot the MICU. ■
  4. Substitute a known-good navigation unit (see NAVIGATION UNIT REMOVAL/INSTALLATION ), 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 and should be considered a characteristic of the system. Report the problem according to the Navigation System Owner's Manual under Reporting Errors and look for improvements in future databases. ■

    NO  -Replace the navigation unit (see NAVIGATION UNIT REMOVAL/INSTALLATION ).
