integrating an ipad into your sound system is a piece of cake. You could run a headphone jack stereo OR run one with the usb2 port, this will keep it charged constantly as well as allow you to switch input modes on the stereo to allow your music to come through. Just keep in mind, law enforcement officers frown on movie viewing from the driver's seat! Also not sure what size memory you have, but 16 gb isn't a lot of room for apps and music. I have 9gb of music on mine and it's only 2294 songs

By the time the kids get angry birds on there you won't have room for more than a couple movies!! Running the usb cord would allow you to swap out and hook an ipod up as well.
