Going to pick up my A3 next week and I wanted to build a carputer for it. I didn't get the nav or bose, so i have just the single din dash. Is it possible for me to change my dash configuration so that i would have the same as the A3's with Nav? I wanted to mount a 7" touchscreen there. Where could i buy the parts, and what would all be involved? Please help!

Great, where do i get it? Do I order it straight from Audi?

the you will need the buttons/cardtray as well as a new ash tray also. The A/C controller can be modified to fit the double-DIN cage but the button can't.
