wait so you bought another ipod interface instead of hooking the DSP adapter up to the Dice one you have?

Either way the USA Spec DSP model will work, I have it installed and no issues. But yes to above, you definitely need the coax to convert the signal.

EDIT: Just re-read the USA Spec instructions, that 3 pin connector you are holding gets plugged into the interface (the one with the brown wire) and the coax plugged into the DSP connector for the amp. the 6 pin is not used on their install.
