Its probably some restriction on CarPlay being a specific screen size to make compatibility easier.Ok thanks guys I guess it will just have to stay the traditional way in the middle screen for now then. Really a shame not to have the basic directions in the center at least.
Have to admit I prefer the look of my old MIB1 unit when i was playing music via a cable. The album artwork looked great. On the Carplay the massive chunky buttons look rubbish to me so once the music is playing I change the view.
