Cursor or MAP Rotates when Vehicle Stopped

WARNING: This page is about a different car, the 2006 Lexus GS 430 and 2006 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.

CHECK CONDITION
1. Check with the customer if the vehicle has been rotated on a parking turntable.
  OK : Vehicle has not been turned on turntable.
  
  HINT:
  
  If the vehicle is rotated on a turntable with the engine switch on (ACC) or on (IG), the system may store the angular velocity. As a result, the vehicle position cursor may deviate.
