Hi, Im new to this forum I have done some reading and like what you guys are doing. Well I just picked up an 08 RRS HSE with the premiun pack and is equipped with the Harmman Kardon Logic7 system but not equipped with rear entertanment, I notice that the amp is located under the passanger sit and it has an optical connetion with nothing in it, so what that hek I try to connect a DVD player just to see if any sound would come out of it and of course nothing happened try to change the modes from CD to AUX just to see if any sound will come out but of course nada. Well I just need to know if indeed that connection is an input and how to activated cause I will like to use it as an external digital source, so does anyone have a clue on how to acomplish this, Please Help!!!!!!!!!

Thanks
