We have just installed a Rear DVD System in to this 2015 Mercedes S-Class . The vehicle is equipped with Hard Backed Neckpro safety headrest and our customer required a system that did not interfere with the airbag system and looked factory fitted . We carried out our Neckpro headrest conversion and installed 2 x 7 inch Widescreen Monitors ( Piano Black ) in to the headrests and re-trimmed the rear of the headrest to match the original trim . We also installed a Digital TV Tuner to the vehicle utilizing the second input on the screens and second channel on the headphones . Prices start from £1200.00 + vat fully fitted inc a 2 Year Parts & Labour Warranty .
