Sorry
If someone else fails to connect the wireless android auto second time after connecting the phone, I apologize for having possibly misled those who tried to connect but could not, I was connecting from the wrong side
For those who have Android version 10, you need to install Android Auto for phone screen, in the Android Auto settings, find the switch to start bluetooth when starting Android Auto, for those who have Android version 9 and below, do the same in the Android Auto application.before turning on the car, Wi-Fi and bluetooth on the phone must be turned off, after turning on the car, you just need to open the Android Auto application and that's it.
When AA starts it enabling Bluetooth and then when needed by AA turning on WiFi.
