I have looked long and hard for a rear seat solution that is elegant and nice and this is it! It is make of good quality, sturdy materials and looks great when installed. I don't use the FM modulator so I can't speak to that. Its mainly used for the kids to watch movies on the go. I did hook my iPad up to wifi so they can surf the web and stream movies as well. The headphones are a nice touch and are good quality. Note: ANY bluetooth headphones will work to connect to the iPad so you can use other options but you can use wired headphones for that matter. I have had built in rear seat entertainment in almost every car but I didn't get it in my last one and this is a better solution than the out of date stuff the car companies put in their vehicles.
