They made the new iphones and touch to charge on only 5 volts like USB voltage. If you have a ipod interface like Alpine's KCA-422i, it will work but will not charge unless you buy a $30 adapter which converts it from 12 volts to 5 volts. New interfaces are supposed to be updated for this problem.You mean an older HU?
The HU will be something 2009...will that charge? I cannot plug into the USB at work, but I can at home.
Things like the iphone seem useless to me. I don't spend that much time on the phone or with gadgets.
