Actually the parking guide lines are a feature of the camera (I tested my camera while out of the car before install). Most current cameras have the feature. As for the moving parking lines, those are part of the canbus protocol, not the older ibus as in the E53 X5. On my 2005 4.4 sports with active xenon headlights, the parking lines do not move while I can see the headlights moving (indicating the steering angle sensor is fine).
