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 12 VOLT 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 accessories or other objects that can block the GPS signal. Always do the Map matching (see MAP MATCHING ) before proceeding with the troubleshooting.
Always check for and resolve all CAN DTCs before troubleshooting the navigation system.
Verify that the correct audio-navigation unit is installed for this model. Go into the 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 navigation DVD for dirt or damage (see OBTAINING A NAVIGATION DVD ).
Check any official Honda service website for more information about the navigation system.
Before troubleshooting, make sure you have the anti-theft code for the audio-navigation unit.
After troubleshooting, enter the anti-theft code for the audio-navigation unit.

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.
Go into the System Diagnostic Mode, and use the Yaw Rate diagnosis (see YAW RATE ) to check the yaw rate sensor.
Is the yaw rate sensor OK?

YES -
- CVT model: Go to step 3.
- M/T model: Go to step 4.
  NO -Replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
Go into the System Diagnostic Mode, and use the Car Status diagnosis (see CAR STATUS ) to check the BACK signals.
Does the BACK signal change from [6] to [1] when the shift lever position is changed from P or N to R?

YES -Go to step 5.

NO -Troubleshoot the back-up lights. If OK, go to step 7.
Go into the System Diagnostic Mode, and use the Car Status diagnosis (see CAR STATUS ) to check the BACK signals.
Does the BACK signal change from [0] to [1] when the shift lever position is changed from neutral to reverse?

YES -Go to step 5.

NO -Troubleshoot the back-up lights. If OK, go to step 7.
Go into the System Diagnostic Mode, and use the Car Status diagnosis (see CAR STATUS ) to check the VSP signal.
Drive the vehicle and watch the VSP signal.
Does the VSP signal change from [0] when stopped to [1] when the vehicle is moving?

YES -The problem may be a characteristic of the system. Check to see if the problem occurs in the same place in a known-good vehicle. If it does, the problem could be in the database. Go to step 11.

NO -Do the DTC 1306: Vehicle Speed Pulse troubleshooting (see DTC 1306: VEHICLE SPEED PULSE ).
Turn the ignition switch to LOCK (0).
Remove the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ), and disconnect audio-navigation unit connector C (8P).
NOTE:
- Eject all the discs before removing the audio-navigation unit to prevent damaging the CD player's load mechanism.
- Remove the PC card before removing the audio-navigation unit.
Turn the ignition switch to ON (II).
Measure the voltage between audio-navigation unit connector C (8P) terminal No. 8 and body ground when the shift lever is in R (CVT model) or reverse (M/T model).

Is there battery voltage?

YES -Replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).

NO -Repair an open or high resistance in the wire between the audio-navigation unit and the under-dash fuse/relay box.
Substitute a known-good audio-navigation unit (see AUDIO-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 manual under Reporting Errors and look for improvements in future databases.

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