I don't think anyone has tried it. Physically it should be doable with the right parts. You have to get new (bigger) screen, new iDrive computer, etc. You can find the part #'s at Realoem.com
I think it's one of those things where, if you want to do it, you have to order all the parts separately from BMW direct...and get someone to install it (likely dealership). Basically, it is going to cost you a lot of money.
At some point these mods are kinda more cheaper to just sell your car and get a new one with iDrive Professional already installed.
