Hello, I find it foolish that my pioneer x950bh has a worthless USB charge part in the rear and to get a working USB port, you much buy an iphone accessory that will further add to clutter as it will comes with an extra unneeded wire and the need to waste more money.

 

Is there a pin-out available for the CD-IU201N iphone/USB plug adapter? If I can find the pins that connect to the data portion of the USB, I can solder the two data pins to the charge port and make it a functional USB port.
