Unable to stay connected to BT

[ChrisSewell]

Running on a Raspberry Pi 4 using a pre-compiled image.

I've tried using my phone to pair to the Pi, and tried using bluetoothctl to pair / trust to the phone.

Previously used Android Auto with this car, and this cable. Have tried multiple cables. Have also powered the pi via GPIO pins 4 and 6 to make sure it's getting proper power separate from the cars dedicated AA usb port.

2022 Volvo V60CC with Sensus infotainment

Phone says looking for Android Auto the whole time

Car displays Raspberry Pi 4 as a list of Android Auto devices
