I posted this above, but in new Lexus RX models at least, the Lexus vehicle management software trumps the AA interface so you're forced to setup their mobile app if you want to use AA (for things like navigation).
On a related note, the Bluetooth stack in my F150 doesn't work very well with phone calls. I can place calls fine, but receiving calls will not route them through vehicle audio. I have to turn on speaker phone to participate. It's a known problem "won't fix" from Ford, regardless of the fact that they've sold millions of these trucks (mine is a 2017 and has never worked).
That sounds like sync 3.. there was a known problem with Bluetooth connectivity but there was a fairly easy way to fix it. I cannot remember but I will look at my ford vehicle tonight for what I did
They want their hands on that juicy data that Google and apple are getting. It's why GMC opted to make their own instead, and why you have to jump through their hoops first.
