I fitted a Tmotec system to my mk7.
All those android systems are pretty much the same, though more recent versions of android are better as they support more functions through software, especially steering wheel controls
The difference for me was down to the location of the electrical connections on the back. Space is tight in the mk7 radio hole, and there's bar down the back which further restricts cablimg and there's lots of that with those android units.
The Tmotec's main cable is in the same place as the Ford's, and the other connections are well over the other side. I still had to break through the bottom of the box to make space for the power connector.
Nearest system to mine on eBay is this one...
