I have a non-iDrive HiFi system w/Professional HU. I also have BT for the phone but not the audio. I am using a Sandisk 16GB USB 2.0 Flash Drive formatted to FAT32 and it seems to work just fine. Very clean audio and the only issue I've had is that it just takes a while to read the entire Drive. But once it's read, no issues.

Edit: After six days, I have noticed that while the car recognizes the USB and never disconnects, it seems to keep playing the same 30-40 songs over and over (I use Random all the time) so I guess there IS an issue.
