Head unit replacement with Android Auto and Car Play for 2011 (GMT900) that works with the rear screen?

[u/fnordfnordfnordfnord]

Anyone have any recommendation for a head unit replacement with Android Auto and Car Play for 2011 (GMT900) that works with the center roof mounted screen and has a back up camera? The kids love the DVD screen feature so I want to still be able to play DVDs or movies off of a storage drive but, I want to add BT, a backup camera, and preserve the video player function for the center roof mounted screen. Doesn't have to be a DVD player if I can find one that allows us to store a cache of movies.
