I'm a relatively new Model S owner. My primary music source while driving is the USB player (I have a 64GB memory stick plugged into the center console). I've been through a few software updates now, and I've noticed that the USB player will consistently forget the ID3 tags (artist, album, genre, etc.) immediately following a software update, and reverts to simply showing the file names (SomeSong.mp3). The odd file here and there will still properly display ID3 tags, but the vast majority just show their file name. The files still play okay, but the user experience is much worse without all the proper song meta data displayed. Waiting for the ID3 tags to show up later doesn't work (they don't). Rebooting the center screen does not help. Restarting the car does not help. Unplugging and replugging the USB stick does not help. Moving the USB stick from port to port does not help. The only thing I've found that helps is to unplug the USB stick, take it to my computer, and do something to "change" the file system. For example, I typically move all the files from one root level folder to another (new) root level folder. When re-inserted into the car, the USB screen says "Loading" for a while, and then all the ID3 tags come back. Anybody else seeing this?
