With IPhone 12 PRO MAX on iOS 15.x or lower:
I have had issues on numerous occasions with Airplay failing to connect. Here is what I have found:
1. If Airplay initially connects on its own, you will have no problems while the phone is in Bluetooth range and the truck is still on. HOWEVER, if I am messing with ANYTHING on my phone (answering a call, unlocking the phone, whatever) at the time the truck tries to establish the connection, then I have trouble getting the phone to ever connect. Even going in and attempting to manually make the connection or shutting off/on wifi/Bluetooth did not seem to work.
2. If Airplay connects and you leave the truck running and take your phone away from the truck and out of range for Bluetooth, there will be problems trying to reconnect. Most of the time, turning the truck off, opening the door to kill total power, waiting a minute or so, then turning the truck back on will allow a connection.
On iOS 16 THOUGH (same phone):
I have not have near as much trouble even if an initial connection is not made (in other words, I’m using my phone when the truck turns on and airplay fails to connect), I have been able to go into the phone settings on the truck and click the airplay button and it has connected every time without issue.
So try updating your phones and see if things don’t get better….
