The Mercedes E-Class (w212) Convertible do not have a standard headrest so installation of monitors is made more difficult . On this vehicle we have installed 2 x 6.5inch Widescreen Monitors in to the seat back with a 6 Disc DVD Player installed in to the boot . Monitors were flush fitted with surrounds trimmed to match the seat back . Installation of monitors in the E-Class Cabriolet take 2 days to complete .
