So I have an update on this. After almost 3-4 weeks of calling Sirius, Guardian, Jeep, everyone - I finally spoke to someone at Jeep who listened. When he pulled up my VIN number, they had the car listed as still being in Mexico, and not purchased by me. He had to actually call the dealership, and they had to fax him over proof of purchase, then it took about a week for them to process the change so I could actually be the owner - then I was able to activate it finally. It was SO frustrating, but finally works now!
