The problem definitely seems to be Carplay related. I did a 35-40 minute drive yesterday, played music through the phone (connected via USB), but didn't launch Carplay. The HU never crashed/rebooted, played fine the entire time.
Has anyone found a fix to the crashing issue? I have an 8200nex and it is literally crashing every 5-10 minutes. Looking online it seems to be the maestro that is crashing, but I have not found a fix for it. Latest firmware I'm seeing from Pioneer is v1.08 which is 5 years old.
