After everything I've read in the owner's manual and from users here, I hadn't bothered to give it a try before, but I thought with v29 it was worth a shot. I've been pleasantly surprised to find that my 64GB drive, with about 41GB of music, has been working flawlessly. It even remembers where I left off after taking the drive out, updating it, and putting it back in. So far the behavior has been better than what I had with my 2012 Focus' MyFordTouch/SYNC system. The 3 is far less picky about the location of the playlist files, too. I haven't used it for long, so I'm not sure if the long load times will be an issue, but so far they have not been.
