A system for controlling a mobile machine is disclosed. In one embodiment, the system comprises an integrated guidance system coupled with a steering component. The integrated guidance system comprises a position determining system for determining the geographic position of the mobile machine. A guidance system coupled with the position determining system is for determining a deviation of the mobile machine from a desired direction. The integrated guidance system also comprises a display coupled with the guidance system for visually indicating a deviation from a desired direction and a steering interface for controlling the steering component. The steering component automatically controls the steering mechanism of the mobile machine in response to a steering command generated by the steering interface. In embodiments of the present invention, the position determining system, the guidance system, the display, and the steering interface are disposed within a housing.
