Are you 100% positive that a simple board swap (which is all that's been promised so far to FSD suckers ^H^H^H^H pre-purchasers dating back to late 2016) gets an AP2/MCU1 car dashcam functionality?
I disbelieve. I want to believe. But mushrooms aren't yet legal in California.
More to the functional point, there are exactly 2 features (of the list promised in late 2016 to AP2/FSD buyers) that I care about:
1. Stop sign reaction (see vaunted 12/2016 video and 1st mention circa 10/2104 AP1 launch).
2. Speed limit sign reaction (this worked 99% of the time with AP1, and fails regularly and often for very long distances even today with AP2 *and* AP2.5).
The clock is ticking.
AP2 never read speed limit signs
