This really appears to be the answer and I am probably going to go this way. I have a question that you may or may not be able to asnwer. I know you have to root your phone (my son is an executive with a major carrier and he's having heartburn over this.) My current phone is a Droid Maxx. MHL is not supported by the look of things. Does rooting the phone allow MHL? This phone does not have an HDMI port, so an MHL adapter would be required. Otherwise, I need to go to a Droid Razr Maxx HD that has HDMI. Does using ARU Reloaded get you past the phone restrictions placed by Pioneer?
Thank you for your input.
Great questions! Unfortunately rooting will not allow you to use an MHL connection on a non MHL enabled device. For our purposes here rooting only removes some artificial restrictions that stop you from running ARU Reloaded. The Razr Maxx HD also doesn't support MHL (no Motorola devices do), but I believe it is confirmed to work with ARU Reloaded via a straight HDMI to HDMI connection.
You are not limited to just the MAXX HD...many devices can be connected to the 8000 and use ARUR in a variety of ways...some through straight HDMI, some through MHL or Slimport, and some via Chromecast (this last is a little more complicated to set up and I don't necessarily recommend it except as a last resort). There are a few considerations, but the primary thing you have to look out for is that you can achieve root on your phone. For example, based on your current phone I am assuming you are on Verizon, and thus would not recommend the Note 4 (the phone I use on Sprint), as unless something has changed very recently root access has not been achieved on the Verizon variant. However, something like a Samsung S5 should be OK using MHL, or an LG G3 via slimport.
The answer to your last question is a qualified...kind of. It doesn't mean you can run ARUR on any and every device willy nilly, but people are running ARUR on all kinds of devices...including some android devices that aren't even phones. For example, here is a video of someone demonstrating ARUR running via an LG G3. Granted, it's on a european HU, though the principle is the same. https://www.youtube.com/watch?v=OcDvsW0Q3_0
The point is that despite the fact that the G3 isn't officially on the Pioneer sanctioned phone list everything still works as intended. Generally speaking, where there's a will there's a way.
I hope your son doesn't get to bent out of shape over this, though I respect his position. Root access allows you to do things with your phone that the carriers sometimes frown upon, though in this case your need for root access is totally benign. If you've never rooted an android device before I suspect you are going to find your research a little overwhelming at first, but for most devices it's actually fairly simple to do. Many devices have a once click root method availalbe that will do all the heavy lifting for you.
Sorry for the long post, but I hope you find at least some of this info helpful!
