This single module allows the user to select and operate several hundred functions within the automobile. Used in conjunction with a monitor and four large buttons arranged in a square around the central rotary/push button, all drive, comfort, communication and audio functions can be easily activated.

The rotary/push button falls readily to hand for the driver and front seat passenger and allows the driver to activate functions without the need to look at them while driving.

A large display monitor in the center of the dashboard displays all the information the driver requires in a simple graphic display, apart from the speedometer and tachometer which are conventional analog instruments.
