I have a 2018 Hyundai Elantra with Android Auto and a Pixel 3, and I use Android Auto often. I recently upgraded my phone to Andriod 10 and after a few days Android Auto stopped working. I have rebooted my phone and tried a new cable to no avail. I had a friend connect an iPhone to my car and CarPlay worked normally, so I know it isn't a problem with the car's USB port.
Does anyone have another suggestion?
