IDK if the location of the box is the same on the 2013 as the 2008, but it is located in the trunk above the rear passenger wheel well if you pull the carpet back. My car came with a free 6 month trial from the dealership as it was a certified vehicle when I purchased it. Definitely worth calling where you got it from to see if that would apply to you. Guy from the dealership didn't even tell me about it. I found out maybe less than a week of having the car to my pleasant surprise as I was scanning through the presets riding around town...smhNo I am not currently subscribed to XM. I am trying to find out if it is XM ready.
I have the XM module in my trunk. I have the antenna on the roof. I don't have XM available as a band. Is it likely just the fuse?As stated above.
Check rear passenger trunk inner fender area for an XM module.
Check XM fuse at passenger fuse panel
Check for XM/Onstar Antenna on roof.
Check for XM Band on radio. You should get the XM preview station for free.
If non of the above exists you don't have XM
