i think 06 models have the socket where you can connect mp3 player to the car but for 05 and below probably, we dont have this thing...
i've seen people taking off interior trim to install stuff in for ipod, etc.
is there a way to hook up my mp3 player (non-ipod) to the car w/o going through all that?

 

'06's don't have any such socket. we'll have to do all that console removal/hookup as well...
