We bought ours from Lenco. And "AV-Out" interface at the same time, if you have "AV-in" selected the input source - For him the "AV-in" function. Thus can be seen in the second display a third display of Lenco connect. All three are thus connected in series, and show the film from the first device. On this we have put an FM transmitter into the headphone jack and can spark the sound to the car radio and then play through the car stereo. For our passengers back we now have entertainment such as in an airplane.
The weak point of this solution: The supplied cables are of course designed for only one connection from left to right and not for pulling cables across the minivan. I will not be included in the vote but because Lenco also only indicates a particular application, the left-right configuration.
