Dman, I assume you looked in the bimmerfest forums. There is a pic of a great double din install in 5 series by some guy in Japan, it sticks out an inch, but looks OEM, he even matched the leather trim to factory dash, very nice install.
Did some searching and just found out that MisFit is not a big fan of euro installs, too bad, still would be great if I found someone who would make similar bezel for a good price.
