This is for a 2006 Esky, but still relevant, as not everyone got the factory RSE.
I am currently working on my own solution for this..
What I have so far is..
Amazon Fire HD 10.1 (no ad edition) x2
Headrest tablet holder x2
2 port 2.4a 12v port adapter (I had one, similar to this)
Rechargeable Bluetooth headsets x2
I am just going to install a VLC player. I have some 15000 movies on my server, and another 30000 TV shows. So I am just going to use a 256g Micro-SD card, and they can watch whatever.
And for trips, I would just enable my hotspot on my phone, and they can use the Philo/Hulu/Disney/YouTube/Prime/etc app, and watch whatever.
My youngest son is still to young to even know how to use a tablet, even thou he is 3.5. We never exposed him to the electronics bug. My other son isnt born yet, so the other seat is for him eventually, or my wife, depending on what we are doing.
Its all getting delivered today, so nothing is installed yet.
Got a busy night, new ALC compressor, rear shocks, and RSE.
I currently have this, which has a DVD player in the center console. But it is very finicky about what DVD's it will play. It works, but the built in speakers are not great.
