some rear seat entertainment diy i did in 2011, simple iPads streaming to head unit, advantage better positioning you can adjust to your liking, no messing with headrest and safety, bigger screen size 10inch and way better resolution 1080p videos playback, plus you can do numerous things like internet connectivity apps etc and then take iPad with you inside so no worry of theft,
