hey guys so i have a panasonic deck with no auxilary inputs on the back but it has a cd changer control plug and cd changer rca inputs on the back, i was thinking of plugging an mp3 player in the back but the deck wont let me choose the cd changer control option until i plug in the controller, i was wondering if anyone has acess to a panasonic cd changer schematic, the head unit, or dual cd changer control unit, so than i can rig up my own controller and use these audio input ports for whatever i want, if anyone has access to such shematics please let me know, it’d be greatly appreciated.

just get a fm modulator.

itll grab a poorly transmitting channel off the radio waves and used that to play ur mp3 player to.

i have one., it works great.
