Hi everyone....I bought a used s550 and love it....my 3rd mercedes so far and not my last....my question is I'd like to plug in my I phone and use the Waze app and see it on the screen on the mercedes built in screen....I understand there is an adapter I can buy but it sounds like I need to plug it into something in the center console....I don't see that plug...only thing inside there is something to charge my I phone...am I missing something here? Any help would be appreciated with associated links....I am not interested in replacing the car's unit with a new one....just looking for a simple plug and play if that's even available....thanks, JIM
