Hi all. I just bought a used '08 Edge (and I LOVE it)! I want to add Sirius radio if at all possible, and am curious how to best go about this. Currently, the system is the basic CD/MP3 arrangement. What are my options on adding Sirius? Would it be better to purchase a Sirius radio and have it installed someplace like Best Buy, or go with a Ford factory option? What are the costs of each? Thanks for your help!
