Due to some budget issues, and not wanting to give up anything, I didn't order my new car with autopilot software. However, due to some viral youtube video revenue, I can afford it sooner than I thought. I was wondering if anyone knew how big of an ordeal it is to add it? Will I need an appointment and to relinquish the car for a day, or can I just swing by, hand over $3,000, and be on my way? Can it even be done remotely? I take delivery Wednesday. I know I should just ask my service center, but I am in Seattle, where they are incredibly busy. So, I wanted to see if anyone had any experience with paid software upgrades before.
