Hi, my mom just bought a 2013 Outback about a month ago and I am trying to get the satellite radio working. In the owner's manual it says new vehicles come with 3 free months, so I thought I would get it working for her. I went to the SiriusXM website in the manual to activate it. It says I need the radio ID and to get it I must put the radio on channel 0. Unfortunately, when I press the SAT button nothing happens. I thought all of them came satellite radio ready? Please correct me if I'm wrong, or if I'm not doing it correctly.
