Hi. I've got a 26 RST. I've had the no audio a couple of times also. It's not related to Apple car play. I've got android. It kinda seems to me you have to turn off the truck and get out to possibly get the remote away from the truck. I came back after a couple of minutes and it was good. I know it shouldn't be that way and is aggravating. I've had mine since March. There was no problem with my 2020.
