my 2017 90D is HW2.0. I have what was known as "Enhanced Auto Pilot". I have all of the cameras (on the b pillars, front fenders, etc) on my car. Within my app, I have the ability to upgrade to FSD for $4,000. Part of that includes the replacement of the HW2.0 to HW3.0.
I dont plan to pay $4k for this upgrade. I have all of the current features that FSD has today, just with my EAP.
