i have made line in jack from inside the stilo original CD Visteon Head Unit
But if you want to do this you have to know how to make solder to little
pins
first take out head unit then cd player and you will see lout-rout and ground (they are very little) on the board under the connector of cd player
then make 3 solders to them then join them with a stereo cable to the 3,5 mm stereo jack that you opened in front of head unit
i use 1 m two sided stereo cable and 3,5 mm jack
it works when u play audio cd from head unit. if u connect mp3 player and turn it on it cuts cd audio
(my car is 2005 dynamic and head unit without hifi model and part no can be seen on pics)
here some pics
