When you open Apple Maps click on your profile image next to the search bar. That brings up a menu where you can select your vehicle. I do remember something about being connected to the vehicle via CarPlay. Maybe you have to be connected to select the vehicle. I helped someone add their Mach-E and I think I remember that the option wasn't there, but we went to the car and connected the phone and it showed up.And I've seen somewhere that a thread showed adding your vehicle to your Apple Maps profile but for the life of me can't find that. Do I have to be on CarPlay while I look?
