Can it be done? I replaced my jbl nav system in my 2010 with a chinese android head unit. A family member just got a 2015 Prius with the jbl nav system but he doesn't like the smaller screen and wants to put my old head unit with the 7" screen in his 2015 car. Only one of the rear plugs are the same, but that one plug powers the head unit on, so that is something. Is this ultimately a fool's errand?
