Even Bill Gates is probably impressed by the 2007 Mercedes-Benz S-Class’s technological wizardry. COMAND, a central control dial located on the center console, operates the audio, climate control and navigation systems. Switches, buttons on the steering wheel, and voice commands can also be used to control the various systems. COMAND’S information screen is now located higher on the dash, next to the gauges, allowing drivers to use the system while still keeping the road in view.
