When you pick up your Acadia brand new from the dealer, is the XM radio already installed and activated? If not, how do you activate it. I am heading to pick up my car and will be on the road for a few days.
My Acadia was less than 12 hours off the truck and still wrapped in plastic.(and still was when I test drove it!) I had to wait for them to perform the new vehicle check-in and buyer prep at the dealership. Maybe it's activated then.
