Hi folks, new to hear hope you can help

Just got a superb new Smax and chose the in car DVD player. Unfortunately as some of you may know it only lays through infrared headphones.

This is not ideal for kids below 3 as they won't keep them on or the fact that it is capable of seating 5 kids in the back but only 2 of them with the headphones can hear the film.

Ford say they have no ideas how to get this to either play through the stereo or if there is a customer solution out there.

My wife really wants this done, please help folks
