The ipod connector I am talking about is not a usb. I am talking about the plug that goes into the bottom of the ipod.
I have an aftermarket tuner that allows me to input my ipod directly into the stereo and control it from the headunit.
The cable from that is wide, about an inch or so, and plugs into the bottom of the ipod.
My ipod plugs into my computer with a wide plug on the bottom to a usb on the computer.
It sounds like a standard ipod connection to me.
