pioneer carrozziera avic-d717

hi all ,,,i pulled this unit out of a import car and with it came beacon,tunner,arials and all wireing,,now the only thing missing was the screen and id say the remote,,on the back of the dvd unit,it has a commuication i/o socket,now this was the only socket that didnt have anything plugged into it, does anyone know is this where the remote plugs into?   or what?   and upon powering up the unit and getting lighta working,i cant eject dvd that is in there as it doesnt seem to have any power running there ,,,is there a trick or special way to hook up these units  outside of the vechle they were put in ? ,,,any wire colours and to where they go would be good to ,,,,thank u all for yr time  and hope someone has a answer or two ,,:)

the best thing to do would be to contact either pioneer or the manufacturer of the vehicle it came out of

My mechanic told me, "I couldn't fix your brakes, so I made your horn louder"
