I too also recently bought an '04 X-Fire and was wondering what would be the best aftermarket stereo system for allowing Easy Ipod playing capabilities. Some accessories work with automatic transmissions, but i have the 6-speed transmission so, these docking stages hamper my shifting ability. What is the best stereo system one can get that would allow direct transmitting of Ipod songs to the radio without worrying about being on the right station, also...Do 2004 X-Fire's have a 6-CD changer option that may be installed as well?
