Yeah the fiber optic loops was not connected at all. matter of fact it was just taped to the back of the amp with plastic covers to cover the ends. So your saying I have to connect the fiber optic loops to the factory amp, then back to the changer.and do I have to take the radio out and connect something to the back of the radio at all. Do I have to go get it programmed at the dealer or should it do it by itself. Thanks alot Gilly.
