I tried my iPhone 16 Pro Max in my car and it's still causing my head unit to reboot. I tried my iPhone in my wife's car and am still having an issue there, too. I've tested an iPhone 16e in my car on the 26.2 RC that worked prior on 26.1, and that's causing my head unit to reboot. Updated to the official 26.2 release and it's still causing an issue. I tried my wife's iPhone 14 Pro in my car before updating to iOS 26.2, so she's still on 26.1, making sure her iPhone isn't listed in my stereo's settings, and it still works just fine! So, yes, I know different cable- but I did even buy a new cable...
We then updated my wife's iPhone from 26.1 to 26.2 and now her iPhone is causing my head unit to reboot. It also doesn't work in her CrossTrek, although there it's just occasionally making that buzzing feeling as if it's connected to something that can charge it.. But it never ends up charging it.
There have been no updates for my car's stereo. My wife and I both have 7 year old cars bought new and this has worked the entire time we've owned these car over the entire 7 years. So Apple has effectively made a main feature of our cars now obsolete, and just a couple weeks before Christmas. Thanks! If this is some part of a master plan to get us to buy new cars, think again!
Now to worry about whether it's worth it to go and buy a wireless dongle to try and connect that way. I feel like I've exhausted all other options at this point, including resetting my stereo.
