This is a complete DVD headrest entertainment system. This MoviesToGo system includes a pair of universal replacement headrests that fit most vehicles with built in 7 inch color screens and DVDs in each headrest. Since both headrest have built in DVDs, you can watch a different movie in each at the same time or watch one movie on both screens. Headrests tilt forward and backward and come with black, tan, and gray skins to approximately match most vehicle interiors (we also sell exact fabric or leather match headrest video systems at a different price). Each headrest also has audio/video, HDMI, and USB inputs for other video sources or game consoles. Passengers can listen to sound privately thru the included pair of wireless 2 channel headphones or everyone in the car can listen thru the cars radio with the built in FM transmitter. Price includes installation in most vehicles. A few vehicles require additional parts or labor and this system will not work in vehicles with factory headrests that are motorized or have air bags in them.
