I'm currently using a P.I.E. aux box hooked up via the CD changer plug on my STOCK head unit in my 02 F350.  I've only got the 3.5 headphone jack attached and it works fine for audio.

Does anyone know if this cable "PIE RCA-POD" also found here; http://www.amazon.com/PIE-RCA-POD-Audio-Adapter-Cable/dp/B000P9UOIO will CHARGE a newer iPhone??

I'd like to use it to pass audio AND charge my iPhone.  I keep reading about 12v charging vs 5v charging on the newer iphones/ipods....???

Thanks All!!!

Ok, I just ordered a cable that takes Vehicle 12v and reduces it down to 5v for charging.  Apparantly all of the newer ipods/iphones require 5v for charging (same as a USB connection via computer).
