so when I purchased my vehicle, my first Tesla, I was a bit naive when it came to options. It seems that I missed having AP by a few months. Can this option be added to a 2014?
If it has AP hardware, yes, otherwise not by Tesla and not at a sane price. Not sure exactly when AP was announced, I think around October 2014 - every car made after then had the AP hardware which can be enabled for a fee, so there are 2014 cars that have it. Do you have the AP camera built into the rear-view mirror base?
