Rather than using a USB port to connect use bluetooth.
Other than my own vehicles, where, when I start the car, Bluetooth searches for my phone, and automatically connects to it if the phone is present, I only use Bluetooth a couple of dozen times a year when I use a rental car.
As I recall it's all wireless. When I initiate pairing, all I need to do is confirm that a 4 or 5 digit code on the radio matches that on my phone. I don't think finger prints could make it any simpler, or am I missing something?
