if ur player supports CD-Changer.........then u can have a Custom made aux cable..........which will be connected to the CD Changer jack
As mentioned before...my player does not support AUX but it supports CD Changer..........so instead of plugging a CD Changer...........i plugged in the AUX cable........simple.
But if ur player does not have the option of CD Changer.......i m afraid its not possible.......or visit any Shop to get more info
