I want to clarify what you mean by the statement "the AP functions won't work with AP/HW1". Presumably, you mean the FSD functions won't work with AP/HW1? I am assuming that after upgrading to MCU2 for those cars we still have auto-pilot, just not the full self-driving functionality?
My understanding is that on my 2016 Model S with AP, the upgrade would result in a much more responsive interface and voice interface, a working browser and some additional streaming and gaming capabilities (which I personally do not care about) but that AP would continue to work as before.
yes, sorry! I meant the FSD won’t work in my AP1/HW1 despite upgrading to MCU2, correct? Same autopilot. I’m guessing how much could it really improve with the same old AP1 camera hardware.
