OK so I've shelved the IPOD thing for a while. While reviewing the manual I see the XM radio for the CC. This it says requires an XM Mini-Tuner and Home Dock. Ok, what are these?, are they Victory items?, how much do they cost? Where and how do they mount? and what's standard XM subscription and any other blanks you can fill in. I live in rural TN hills and radio reception comes and goes with few miles. Any CC owners using XM? Is it worth it?
