Instant Traffic and Weather

XM Radio rolled out their new instant traffic and weather service in 21 markets around the country. The channels offer 24 hour traffic and weather reports for each area. I added channel 212 (Philadelphia) to my presets...the sound quality is a little weak (sounds like a poorly encoded, low bitrate MP3 file), but I'm guessing they highly compress these voice-only channels to save bandwidth for the better-sounding music stations. XM also broadcasts the temperature and weather condition to the screen of the XM receiver, which is nice, although presumably if you are already in your car you have at least some idea of the weather conditions. :-)
