Removed from my 2011 Jetta TDI. It is FLAWLESS. I have the unlock code. $380 shipped OBO. Located in Alexandria, VA.
It will physically fit into a MkV, but there's something about them draining the battery down if you don't have the right version control module. You'd have to search around on here to get the details. Or maybe someone else will chime in that knows about it for sure. Sorry I can't help more.
