Oh man el_freddo you just reminded me I've got an old iPod. I'll have to dig that up and keep it in the car now.
I spliced 12v power off the light for the ash tray, which I really don't use. The inputs and outputs off the box after connecting power are super plug and play. The box has RCA left and right stereo inputs (which I attached a RCA to 1/8" aux cord to). It has a cord to plug your antennae into, and it has an output antennae cord that goes into the factory stereo.
The box came with its own on/off switch as a wire on the 12v power line. I cut off the box's power switch and attached it to this toggle switch that already existed by my steering wheel.
Shopping for wireless coils now and it looks very promising.
