iPod / XM / Changer Solution in my 986

[Acid_J]

I powered mine by stealing power from the back of the head unit (this meant that I didn't need a ground loop isolator because the ground for everything was with the head unit). You can also grab power/ground from the cigarette lighter (constant on) or there is also a small connector behind the console on the drivers side that is used for a phone install. You can get power and ground from this.
