Do you a have a steering wheel icon to the left of your speed? Usually grayed out, but turns blue when AP is activated. If not, you didnt get EAP turned on from the factory. I paid for it, but it took a call to tesla for them to admit it wasnt turned on predelivery...they can enable EAP over the air.For those that had AP calibration issues, did you have any cars, lines or anything showing up in the display or was it completely blank the whole time it was "calibrating"? I'm at 80 miles now and still no EAP, but I do see accurate images of the other vehicles around me on the display.
