Readers rather well thought: all cables are provided (mains power supply for 2 screens or coupled cigarette lighter power supply), one can have the same 2 images (1 DVD for 2 screens) each in DVD or independently. There 2 independent remote controls (each only works with the screen: what other manufacturers would have perhaps not thought of). The audio output from the speakers is sufficient to clearly watch a movie in a car (highway, road, etc), I expected audios helmets extra, but I have not needed! I regret that the head restraint ties to secure the screen in the car not be simpler to install (screw driver required for 4 screws)
