That's a fair comment to some degree...it would obviously be better if it never happened. All I can really say is that it's not unique to this system. Same thing happens on occasion with my mother's Subaru Outback with wired CarPlay, and I've seen it a time or two on other native infotainment systems I've used. I can't say for sure whether the issue is with Pioneer or CarPlay in this case, as it's tough to diagnose when it's only happened twice in many months of usage and isn't reproducible.This sounds like a major defect and it's being shrugged off. Can you imagine if Apple released a $1200 car stereo and you had to pull over, stop your vehicle and restart your engine just to get it working again? That would be a MAJOR embarrassment. Why does Pioneer get a pass here?
And yes, my Macs kernel panic once in a while too.
