OK, I know that my 2015 5.0 ultimate cannot be upgraded to android auto (I'm still kind of annoyed about that since the salesman said that would work). I am wondering though, what does it really give you? The one thing I really would have liked if possible is to link the head unit into real time Google maps. Right now I subscribe to the Bluelink service, mostly for this. I have debated about seeing how expensive it would be to replace the whole head unit with a new one that has android auto (if even possible). But I am curious if you really gain that much.
