I'm not sure if any of you are already doing this or how useful it is, but you can screen mirror your phone screen to your rear entertainment system by using goggle Chromecast or many other casting devices. I already had a chromecast so that's what I'm using. Now i can watch youtube, Netflix or whatever from the phone wirelessly on the rear entertainment system. A lot of these devices are inexpensive and don't require an Internet connection so they are easy to set up. Since the chromecast requires wifi, it was a bit more complicated to set up but not so bad.
