I have a 2006 F-150, there is a pod in front of the rear view mirror. On the left side rear there is a button, what does it do. I ask since two dealers have no idea what it does and there is no picture or reference in the manual.

Thanks
Mike

 

You pushed the button?!

If you press and hold the button you will enter the "Compass Calibration" and you will need to drive in circles slowly to re-calibrate the compass.
