Playon Zoomgo Wireless In-car Cinema Entertainment System

I'm not completely sure how this works because I've never had an opportunity to try it out. But it looks like you can either find media from the PlayOn app, or load media onto the included SD card and stream them onto up to 4 devices at once. It plugs into your car outlet. It does come with a 15 day free subscription to PlayOn, but I'm not sure if the code is still valid today. All original packaging and directions included, but it had been opened before.
