Actually, I mis-spoke here. It looks like with the latest Sync update I applied to my car, I can get USB sort of working, assuming I plug the phone in when it's unlocked.
Indexing is quite a bit slower than iOS devices, (it didn't finish indexing roughly 1500 songs in a 30 minute drive), and overall it's pretty flaky, but it's actually better than the bluetooth options.
