The Audi I drive has a Bang and Olufsen and yes - I can tell the difference between wired and BT. Mostly however I like the safety and convenience of on screen control and seeing album art etc.
I just wish we would have known sooner about no video out. In the long run I am sure an adapter will come out that will solve the issue.
Yeah you have a premium audio system. I do not. My Nissan is stock. I think it just a Bose CD changer but I'm pretty sure my speakers are not, or else Bose speakers suck. I was upset at first about this adapter shennanigans, but since it really doesn't affect me, I'm going to be putting a new deck in to go BT and do away with wires. By the time I'm able to afford a nice luxury car and premium audio system we'll probably be on iPhone 10 and they'll have some new standard or something.
