This is most likely a one-of-a-kind rear seat entertainment system. Vehicle is owned by Santana Moss of the Washington Redskins who wanted a video system in the rear to occupy the rear seat passenger. The rear seat backs were removed and stripped of their leather and then fabricated to house an Alpine 6.5" video screen. The seat backs were then re-upholstered in matching material and the monitors were pressed into provide a seamless look.
The factory COMAND radio was then custom coded to activate the rear seat controls, allowing the front DVD player to be played on the rear screen. A feature not available on the CL Class of Mercedes-Benz.
An extra DVD source was added to the system, an Alpine 6 Disc DVD changer, which was located in the trunk. It can display the DVD on any of the rear screens and/or the front Mercedes-Benz COMAND navigation system
