I just got my mini iPod 6gb, and I want to create a docking station like the made once in pimp my ride, I want to slide my iPod into it, and then it'll be charged and it'll be possiable to hear it by the car's stereo. I have an amp in my car and a kewl panel, if you need to know what, ill write, but I think it's possiable, just dunno how
What's the model of your head unit? Alpine makes an adapter that works on some of their stereos, it works perfectly. I've got one myself.
If you can find a line-in in some form or another on your stereo, it should be quite easy. Really just mounting a dock somewhere and running the wiring neatly.
