I would have suggested a dongle for wireless Android Auto (or something similar for CarPlay), but it turns out the USB data port is always powered on, even with the car turned off. This makes things a bit funky between the phone and dongle. I may try again later, but for now I'm setting aside my Carsifi dongle. Also, my Galaxy S21 is one of the phones that overheats and stops charging on the built-in charging pad.
For these reasons I have some short USB cables with 90-degree heads on order to use for wired AA and charging.
