Audio Systems: Chevy 2002 Trailblazer system, pa11, source button

Question
My wife drives a 2002 Trailblazer with the stock sound system with the Bose option.  I am looking to add her IPOD as an auxiliary input.  Should I use an FM transmitter or should I try the wired approach?  I am not handy enough to dismantle the entire dash for this so I guess I need to know how hard it would be to try the wired approach.  Any other suggestions for IPOD would be really appreciated.

Answer
stay away from the fm modulator you will hate it  
it is not to hard to remove that radio it takes about 15 to 20 minutes   this are the ipod options
