I used the Sik iPod cable (with seperate line-out and power), a Panavise in-dash mount, a ProClip iPod cradle, a 3.5" to RCA audio cable, a Radio Shack auxiallary power outlet and a switch to turn the power on/off. The iPod is hard wired into the Xterra with only 1 cable emitting from the dash.
Enjoy the pics and feel free to ask detailed questions.
