Oh yes they stations and shizz you will lose I thought you were talking the whole thing in general

What factory head unit do you have?? the one with just the bass/treble sliders or the factory 7 band equalizer one??
I have had the bass/treble one, an aftermarket sony one, and the 7 band equalizer one in my car. The 7 band one was my favorite because you can tune the sound pretty good but both the factory ones are very under powered if you just have the standard 6 speaker audio set up (no delco or bose amp). I also have the four bose speakers and the special rear deck piece in my 2000 se which is kinda cool just cuz se's didn't come with the 8 speaker set up. If I actually wired them correctly it would be a pretty good set up.

Anywhoo the best way to go if you like loud is aftermarket, prolly a pioneer or a sony

97-03 are 1.5 din, most touch screens are double din so without modifying your dash it wont fit, several people have done the modding though
