Call me crazy, but I want to keep my single DIN audi CD player and put it in a double DIN cage. The aim is to drop the climate unit down and free up some space for a custom phone/tablet dock between the two. I figured I would get a double DIN to aftermarket single HU facia and Dremel the top half off to leave me with a neat tray onto which I'd start to fab. my own dock. But will a single DIN unit fit the double DIN cage, or are the mounting points where it would click in completely different? Thanks.
