I had a great sales experience, but I didn't understand how great until some of the posts here. I spent at least an hour with my sales guy setting up and testing everything (other than HomeLink and my home wifi connection). The fact that this isn't SOP at every Lincoln dealer is unfathomable to me. How could any new owner of this car be allowed to drive away without even setting up his Google account???
OP, there's soooo much to setting up this car, even for a techie like me. Honestly, I'd get in the car, drive to the dealer, go directly to the sales manager, and demand (politely) for the set up that you should have got before you left the dealership the first time.
