how do you tell whether you have ap1 or ap2? and whats the difference? tx...
If you have a Model S built prior to October 2016 and it is missing the cameras in the B pillar between the doors and another camera in the repeater light on the front guard you have AP1. Not sure when Model X came to HK but most if not all will be AP2 or later. All Model 3 are HW 2.5 or 3 and I understand can be upgraded if you have bought the FSD package.
