I bought a $10 Bluetooth adapter that plugs into the cigarette lighter hole and then an aux cord in our 2010 vehicle. It works significantly more reliably than our other, 2020 vehicle with built-in Bluetooth, touchscreen and all the bells-and-whistles. Seriously, I turn my 2010 car on, “successful connection” every time within seconds. The 2020, I inevitably get failed connections. I don’t think my phone has connected to it first try, once. And then sometimes it fails to connect either the audio or the phone calls. Or, I get it connected and my wife gets to the car with her phone and suddenly my Bluetooth connection is gone and we’re listening to her phone. It’s just infuriating.
