As aggravating as it is the auto industry has been struggling to keep up with tech for ages. It just changes at an exponentially faster rate. Ford probably made the decision to use those monitors in late 2016. They also have to pass crash testing, heat etc. Take one look at caddys CTS main screens that pop any given moment due to heat. I know I'm making excuses but that is the current reality. Now a lot of manufacturers are offering mounts for devices you already own because they have given up.
I'm honestly not mad at the tech side of things with the rear ent. I just can't fathom why they didn't integrate it in any way shape or form to the front? No audio over the speakers? I can't stop the video from the front?? It might as well be an iPad back there. Having the (now) factory supplied Roku fixes all the processing issues you are having. I can cast from any device, so technically I can control it with my Android phone or my wife from her iPhone up front no problem... Really the only issue is you get one stream. The other input has to be the SD card or usb if you want to watch different sources. Not a biggie for me as we are about to have our first kid but I could see that as an issue for some. I have yet to see how a single 4g connection handles 2 had streams... I imagine not well unless there is a SOLID connection.
If that grinds your gears I don't think you should take apart the main infotainment. Considering mine can't even handle it's own startup sequence without stuttering its way to an arguably very dated looking menu system I bet it's just as depressing hardware wise...
