Vehicle Icon Wanders When Driving or Spins When Driving

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

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 GPA signal. Always perform Map matching before proceeding with the troubleshooting.

1. Go into the Diagnostic mode and do the Navi System Link diagnostic, the Navi ECU diagnostic under "Unit Check", the Car Status check, the GPS Information check, the GPS Detail check, and the Yaw Rate check.

Are all the tests OK ?

YES - The system is OK at this time.

NO - Repair the affected system. If the problem persist, swap a known-good navigation unit and monitor the condition.
