A display control and antenna positioning apparatus for a display device is capable of detecting positions of a navigation antenna that receives GPS signals. The navigation antenna is moveable such that a user is able to move it to an open position that is suitable for GPS signal reception, or to a closed position not suitable for GPS signal reception. When the navigation antenna is in the open position, the apparatus enables navigational functions while prohibiting non-navigational functions. When the navigation antenna is in the closed position, the apparatus disables navigational functions while allowing the non-navigational functions. A device mount prevents the display device from being received therein when the navigation antenna is in the closed position.
