As I mentioned in another thread, yes, they are the same, but one works and one doesn't--namely the ipod works fine in my mazda, but the iPhone doesn't. And apparently someone mentioned that Apple designed them differently, which is annoying!
My bluetooth works great in my 07 Acura TSX but im having trouble with the aux cable! My car has an aux plug port in it but when i plug it into my iPhone i have to push it in hard and hold it down for the music to play in my speakers and if i let go it pops back out! Annoying.
