Got it installed tonight. Little more info than posted above.
Yes, it's fairly easy, plug and play and it works. Here is the direct link on Amazon:

Key points:
-I used this as a basic guide for taking the dash apart. If you follow steps 1-4, you will have it opened enough to install

-Getting the center console cover off was a *****. Like took me 25 minutes and I almost gave up multiple times because I was sure I was going to break the plastic. I don't really have any good tips here. Not easy. But once you get it off the rest is simple.
-The radio brain has a plug already connected to it. The harness this thing comes with has an end with a very similar plug and a female connector. Then it also has a connector/plug that goes to the box itself. Install is super simple. Take the male connector out of the radio brain, plug it into the female connector on the unlock box and plug the male connector from the unlock box harness into the radio brain. Make sure your other plug/connector is plugged into the unlock box and that's it. I taped it down to the floor of whatever is below the console cover/cupholders. Put everything back together and that was that.
-You have to hit the rear defrost button twice to activate the in motion unlock. Little message pops up on the radio screen. Confirm and bingo, it works.
-Text messages do not appear on the screen for me. It seems to be dependent on your phone. I have an S7.
