so i have a 2004 tsx with a navigation system 6 cd changer.

It says that there is no CD in there, and when i try to put a cd in there it doesn't want to take the CD.

WTF ... ? is going on, and how do i fix this?

 

try to do a battery pull. remove the negative for about 30seconds, put it back in and try it. just remember to have your radio and navi code on hand.
