Satellite Radio for '03?

[LoLo]

I have a Roady 2, which is great inside the house, but sounds really crappy in the car. (The sound is just plain FLAT going through the "unused FM station" thing...)

I think I have seen that there is NOT a GM satellite radio kit for the 03 model... right?

As an obvious and self-proclaimed techno-moron, what are my other options for a good (and easily installed -- no, not me doing it, thankfully! ) satellite radio?

I have just about given up with the poor radio reception due to the factory antenna and need another option!
