I'm looking into satellite radio but I'm a little confused.... I want something that I can take in my car, bring in the house, and take in the boat. I see they have "dock & play" radios, but how do I find out if that thing will hook up to my current home audio system? I don't want to get a boombox thing for it to plug into. I want it to hook up and play out of my home speakers just like my iPod does. Then I was just thinking of getting the "a la carte" music package.
