I just purchased my new 2015 Rav4.. I love everything about the car except for the guidance system. I want to remove the head unit and replace with one of the China built units that run the android system. Has anyone ever removed one of the gps head units? Is there any reason that the China built units will not fit once i remove the gps head unit? I have been told that if the car has factory GPS that the china built ones will not work. Unfortunately the manufacturer has fairly broken english and i don't think they are understanding my questions. Hopefully someone out there has done this and can confirm for me.
