I bought this car used in September and am absolutely in love with it. Best car I ever owned even if it is used. I am confused though about the radio system. The radio shows AM-SAT, but I could not get the SAT work. I've follow the direction via the manual to try to get the radio ID, but it will not go to the CH000 to give me an 8 character ID. Do I not have the XM radio availability or do I need to be doing something else? What do I need to do to get the XM working/
