Big difference comes that when you plug in your phone, the interface (how the phone talks to the car) is for the most part proprietary, while Bluetooth is standardized across different handsets and manufacturers. This is why you see the same type of support with BT across multiple handsets, while extended plug in functionality is limited to the iPhone e 4/4s.
I just talked with a friend who is an electrical engineer about this subject and he said that BT definitely has reduced sound quality compared with direct USB...so I think I'm going to load music onto the HD and when I want to pay from the iPhone I'll plug in. I did spend the money for premium audio, so no sense in feeding it low resolution data.
