2022.12.3.1: almost everything works. Audio all good, rear hatch opening right, basic AP is working great.
Only minor thing is new steering wheel heat icon on the bar does not trigger the heater unless HVAC is on. Once HVAC is on, and heater toggled, then it seems to work in all cases.
Also: defrost/defog icons work right, with HVAC off, and leaving the HVAC on after switching off the defroster (if HVAC was off at first) makes sense to me. In defrosting/defogging conditions, once the windows are clear, probably good to keep the heat on to keep them clear.
