I gave up on it... and gave up on GM. The vehicle itself was fine, but Car Play _IS_ my infotainment system. I now own a Santa Cruz (I'll let you look up the brand.)

Considering GM intends to drop all support for Android Auto and Apple Car Play in their vehicles, I believe it's safe to say they don't intend to address the problem.

According to recent reports, the way GM is fixing the problem is by eliminating the interface entirely in future vehicle... making Google's Android their default operating system and disabling both Car Play and Android Auto.

We realize you don't like to hear this, but GM has been ignoring this problem for over FIVE YEARS, blaming the third-party vendors rather than your own software engineers. Apple and Google engineers have done what they can and have performed multiple updates and redesigns to clear the problem and improve functionality but the problem always comes down to the GM vehicles and almost no other brand of which I've been made aware. This makes it blatantly clear this is a GM problem and is more likely to cost GM some of its customers if it isn't cleared up. The OTA updates to the stacks have been seen to exacerbate the problem as well, especially when it tries to perform an update during a period of frequent stops and starts, such as when moving between multiple bays of a warehouse or whatever to load cargo from different vendors, or different kinds of cargo from one vendor in different storage bays. Such frequent starts and stops completely confuses the stack.

GM keeps blaming Apple while Apple blames GM. The interesting thing is that the problem is almost identical with Android Auto, meaning that it is almost definitely GM's interface that is at fault, not either of the software platforms. Yet... GM refuses to acknowledge the possibility.

It's definitely a software problem with GM's Android Auto / iOS Car Play interface. It's now a complete failure on my iPhone 13; I cannot connect to the truck at all with Car Play, though bluetooth phone and music transfer are seamless.

The issue truly appears to be with GM's interface to Android Auto/Apple Car Play. About 2-3 hours of straight playback from an iPhone through the system tends to trigger first an issue with the audio starting to cut out, then the reboot can trigger almost any time after that. I even noticed on one occasion that my turn signal audio cut out while I was waiting for a traffic light which also made the dashboard indicators flash both sides just before the stack rebooted. However, when I just play through bluetooth rather than ACP, it works just fine, though lacking all of the communications capabilities through the steering wheel control (like triggering the voice-activation and attempting to make phone calls or voice messages.) Prior to these indications, I suspected the problem was in the phone itself. But I also noticed that any volume changes made in the vehicle tend to stick with the phone when leaving the vehicle. Most certainly the issue is with GM's interface software.
