It is likely a mix of things, could be tied to location, production date, current software itteration. I am also guessing it might have to do with your current phone update. Like if my phone still isn't able to get the latest Android Auto update (8.8.6) while I am still on 8.6.6, that if the car does update I wouldnt see any update to Andriod Auto. Purely conjecture, but seems like the Apple folks have been getting it sooner =PI recently got my update but how do they occur? I know it’s cellular and not over the internet but is it sent out over a certain region? Where all F150’s in a specific area get the update. I can’t wrap my head around how it seems so random on who gets it and who doesn’t.
