If you have FSD computer & MCU2 you should. If you have AP 2.0 or 2.5 computer + MCU2 I'm not sure. I just want to make sure everyone has them because they would be part of the reason for us to upgrade & it seems like some people report they don't have them. But I'm starting to think it's just a matter of knowing how to display them.
You're right. I had upgraded to MCU2/HW3 and didn't even think to check this. I HAD brought up the rear camera while driving, but there doesn't seem to be an option to display the side cameras in this mode. But in actual reverse mode, you CAN slide down on the screen and the side cameras appear.
