The original Delphi Roady (left) and the new Delphi Roady2 (right).

What happens when you take a good product, reduce the size and weight, add more features, and make it sound better than before? If you're talking about XM satellite radio hardware, you get the XM Roady2 plug-and-play satellite radio receiver, by Delphi. The Roady2 is the next generation of the original, wildly popular XM Roady in-car satellite radio tuner. It's not a replacement for the original Roady, just another new option. Can I say that, right out of the box, I loved this new option?

In case you've been living under a rock for the past couple of years, XM Satellite Radio is one of the hottest new technologies available to date. One hundred and twenty digital channels beam down from two geo-stationary satellites, offering a huge variety of music, news, entertainment, talk and most recently, local weather and traffic for 21 markets. All of the music channels are commercial-free, and the sound quality is excellent — far superior to MP3 players with bitrates lower than 128 kbps.
