With the Roady and the subsequent , Delphi introduced two mighty-mite XM radio receivers; they're small, loaded with features, and easy to install in cars--hence the name Roady. With its beefy three-piece MX5021 speaker system, Altec Lansing lets Roady users bring their iPod-size receivers indoors so that their listening doesn't end at the driveway.
For the record, Delphi already offers a home-adapter kit for the Roady receivers. The $40 add-on plugs into your existing speakers or A/V receiver. You'd upgrade to the 2.1-style MX5021 system if you'd prefer listening to XM programming in a room of the house that doesn't already have an audio system. (Note that Altec Lansing also makes a PC version of the MX5021--except for its lighter color and the lack of a Roady cradle, it's basically identical.)
The THX-certified Altec Lansing MX5021 comes with a desktop docking station that attaches to your Roady or Roady2 and the subwoofer; left and right speakers are plugged into the sub's rear. You also get an XM antenna, which you'll need for home reception, and a small remote. The cable length is adequate for most setups, but it also creates a rat's nest of wires in cramped spaces.
