Logic 7 is not a format, remember that. It's not like DVD-A (MLP), SACD (DSD), or DTS-CD (DTS WAV). It artificially creates multichannel sound from a stereo signal.
As far as I know, DTS-CDs are the only native multi-channel audio only discs the 3 series will play. And that's probably only if you have Nav (I assume only cars w/ Nav have DVD drives?). You can download DTS-CDs via torrent (thepiratebay) or create your own from dvd-a discs (takes a little work).
Of course - I'm basing this on my experiments w/ a 09 335i with Nav - not my own car.
