I am on 3.0, for changing tracks and sources it seems to work pretty well, but everytime I try to make a phone call it calls the wrong person. Examply everytime I've tried to call my wife her name is Cheryl, I say CALL CHERYL, it waits a second then says 'calling sarah', i've also heard, 'calling brittany' I can understand sarah as they can sound similar, but Brittany?!?!? really?
I mean it sucks that it doesn't work great for phone calls in my experience but I still love the head unit, it has more pros than cons.
