I have the system in my pacifica, and my kids were late teens.. 15/16 when I got it.
It is the least used thing in the vehicle. I get it for some folks, but with tablets and laptops readily available, this is the usage scenario.
I would have liked to see at least 2 regular 3 prong plugs in the back seat area.
if I were a decision maker at jeep, I wouldnt bother offering the entertainment system.
