im pretty sure my 2003 neon has a cd changer. on the cd player, it has the numbers across the bottom, 1-5, and on the 1, up above it there is an arrow pointing up and the word disc, and on the 5, also up above it, there is an arrow pointing down, this does mean that i have a disc changer right? and if so, how do i get the thing to work?

no, there is a changer that you can get. it mounts down below the cdplayer. down at teh bottom, you have a cubby now. it goes in there, and it wires right into the back of the cd player. it took me 5 minutes to install mine when i got it. you can find it used for $100 or less if you shop around. i did some work for a buddy, he gave it to me in exchange

I have a stock radio and CD changer from a 2001 R/T I believe, in good condition. Let me know if you are interested.
