i just register for sirius satellite radio. i have a pioneer cd player its a model mosfet 50wx4. on the radio it says xm ready,got the radio second hand, went to see on the pioneer site for information on what it means and couldn,t find the answer.i don,t like wires hanging all over the place so i thinking there might be some way off hooking it up too the radio. currently its working with a radio station i find i get a lot off interfierence.anybody know what is meant by xm ready?
