The trigger device is configured to identify a trigger event. The processor is configured to implement one of three operational modes of the display system based on the speed and state of the vehicle: a first operational mode when no trigger event is identified, the vehicle is on, and the vehicle is at a first speed; a second operational mode when no trigger event is identified and the vehicle is at a second speed different than the first speed; and a third operational mode when the trigger event is identified. The processor is further configured to render content on the display based upon the operational mode.
