Does anyone know what the part number for the fiber optic lead that connects the following:
Nav DVD player
CD changer
Voice
Phone
Amplifier

I have the parts for a Navigation upgrade except for the link. Also if i don't have the voice & phone module yet, does the navigation & cd changer work with the complete fiber optic link? Or do I have to buy a different link everytime I get the other module.

Thanks in advance.
