While driving my Model 3 and Y, I have the ability to see the view the cameras on each side of the car (on the left/right side of the fenders). I have late 2016 S with AP2.0. How I get I get access to these cameras? I believe my car was manufactured during the transition period from AP1 to AP2. How do I get the camera views to side marker cameras? Do I need to upgrade to MCU2?
