iPhone 12 Pro Max wireless connection with Pioneer

Hi,

I recently upgrade my card unit to pioneer avh-w4500nex. I’m having issues with my iphone 12 pro max, the unit connect with my phone and does carplay fine. The issues comes when I turn off my car and turn it back on. The blueetooth and carplay bia wifi should automaticacly should connect but it doesnt and have to connect Bluetooth and then lauch carplay and sometimes it recognize it. I took it back to the car audio shop and they check the yellow cable which is for power and is fine. is any one else having this issues?
