I drive a 2006 Mazda 3 5 Door and love it except for two things. The A/C is crappy and so is the stock stereo. I keep toying with the idea of replacing the stereo and these new Sony Xplod in-dash units might make me finally pull the trigger. Sony has introduced 4 different radios that range in price from $80 up to $160. So pricing isn’t really an issue. The top end model (CDX-GT650UI) has several features that appeal to me, including the ability to customize the illumination color to match the color that your car already uses. There are 35,000 color choices, so I don’t think I’d have a problem picking one to match. It also has a front USB connector for use with an iPod or other MP3 player, as well as a front aux-in jack. It even has an application called SenseMe that automatically organizes your music library into custom playlists to match your mood.
