2005-2007 Z4 coupe/roadster AAC on a USB stick??

Can the standard supplied stereo play AAC files off a usb stick?

If not, is there a reasonable either BMW approved upgrade or is it possible to whack a normal single DIN stereo in there?

I haven't bought one yet. I was checking whether you could just swap it. I have done with another BM but the Z4 one looks even smaller than a standard DIN but it can't be smaller can it? Not seen any with the nav unit but that would be better as that would be a double DIN?

That's very helpful, thanks
