I misread your previous comment has the problem originating _inside_ the headunit. Just wanted to clear that up since my response probably seemed pretty superfluous.
No, you read it right. I mean - clearly I don't know the origin. My Mazda OEM head unit was slow and unstable out of the box, and continued to be so when I installed Mazda AIO Tweaks (with Android Auto.)
Specifically running Android Auto became more unstable in March 2020, without being the head unit updated. In other words, probably the phone (Android Auto) was updated. Possibly in a way that was backwards compatible with OEM Android Auto, but not the AIO Tweaks version.
That's a long of saying, there's probably multiple potential sources of problems and failure; not clearly the hardware/software of the head unit, and not clearly the Android Auto software. But a bad combination of the two.
But it's all guesswork on my end! When I see others having the same issues with OEM Android Auto, it does make it seem more of a clear Android Auto software issue. (And we haven't really ruled out idiosyncrasies of the handsets and USB cables.)
