Hi, I'm total nub here.
I just installed new head unit in my 1999 S320. Everything seems to work just fine except when I play CD/MP3 there is no sound coming out at all. Whenever I switch to radio everything works perfect.

Do you guys have any ideas what I did wrong?

Any inputs will be greatly appreciated.
