The interface includes four touch pads disposed in four quadrants of the interface, an outer rotary dial positioned substantially at the center of the four touch pads and an inner rotary dial disposed within the outer rotary dial and being concentric thereto, where the inner rotary dial also operates as a push button. A display screen displays the operation of the interface, and includes a first display portion, a second display portion, a third display portion and a fourth display portion that are provided as quadrants on the display screen and are representative of the touch pads on the interface.
