2022 Hyundai Tucson CarPlay disconnects Temporary Fix
I have had CarPlay disconnect randomly from my radio. I've tried all the fixes, resetting phone, restarting car, deleting the setup and start over. All with little to no success. I have however found a temporary fix.
There is a reset button on the radio. It is on the left side of the radio beneath the volume button. It is an indent. You will need something pointed but not sharp to lightly press this button in. This will do a reset on the radio. After the restart which only takes a few seconds the radio will connect to your phone and you should be good until it happens again. I've had this happen on trips where my gps went away at a bad time but after reset it came back and I was good to go. Hope this helps
