What are you looking for the S-Class Command unit to do for you? If you attempt to install it in the center console, as it is located in the S-Class, you will have to loose your ACC control unit and there is no interface available permitting the Command unit to communicate with the W210 climate control. The same situation applies for the radio: no interface available to permit the Command unit communication with or control of your factory audio system. None of the steering wheel Command Center control functions will be available. This basically leaves you with a grossly (!!) overpriced GPS system, with no factory warranty, for which you will have to gut the vehicle's interior to install.

If you want factory GPS, purchase a MY 2000 E430 with the $1995 Command Navigation center option. The Command unit won't offer all the bells and whistles found on the S-Class but you'll get a warranted, functional GPS, audio system control buttons on the steering wheel and a W210 chassis that has had numerous improvments since MY '98.
