I just downloaded my SiriusXM . It won't let me register. I filled in the blanks first name last name email phone number (only number I could give them was my cell phone number) and zip code. Then it said no account found ( as if I already had one which I do not) and it asked for a radio Id which I do not have. Why is it doing this to me?? It thinks I'm trying to log in when I'm trying to register for an account. It doesn't understand that?
