If someone is in my car and they want to play music from their phone, is there an easy way they can connect outside of bluetooth? I have done it before when they are connected to the charging USB port but can't remember how I did it. I thouhgt I just select the phone icon and I will see the connected phone. My daugher was in my Model S and did connect to the power cord but when I selected the phone icon, it gave me the options for my phone.
