Double Din

[xjman18]

I have a 2007 M45 and am wanting to put a double din screen in it. I know that the radio ac controls and other features are all tied into one. My question is does anyone know if you can put a carputer in that would allow me to fit a bigger screen in and still have the ac controls and other features operational. I am certified in car audio electronics and know that almost anything is possible these days just wanted to get some advice before I move on.
