You're confusing multiple things. The reason why AP1 and AP2 cars can't have the dashcam feature and AP 2.5 cars can has nothing to do with software, licensing, Mobileye, or camera types. It's a hardware/wiring issue. There is a physical connection between the AP 2.5 computer (which gets the camera signals) and the MCU 2 computer which ultimately allows a video signal/file to be sent to the USB port and to a USB stick. That connection does not exist in the AP1 or AP2 cars, so there is no way for the video signal to be sent to a stick and saved. I think it was
@verygreen who reported this difference but am not sure. As I understand it, doing this would require replacing both the AP and MCU computers as well as additional wiring in the car between those units and the camera(s).
