@chinnam3 - Did this get resolved for you? What are you looking for to confirm that EAP has been enabled on your car?
I ask because I think I may have the same issue - added EAP very late, and it's listed in my account but no clear indication in the UI that I have the functionality. I have an Autopilot menu in the "quick controls" UI, but don't see a specific reference to autosteer or TACC. I think someone mentioned you'd get some sort of warning UI that you have to agree to once it gets enabled. Can't recall if I may have excitedly opted-in to that at delivery time when I was browsing through menus, or if it only shows up AFTER the 70+ mile calibration is complete.
