Hi @fireblaster0072 ,
Are you sure it's a tiny screw and not the tip of a 3.5mm plug, that has been broken off when the cord was removed?
In any event the system will have to be removed from the dash and opened up to gain access to the socket which most probably will have to be replaced.
Trying to extricate anything from inside the socket will probably damage the spring connectors which make contact with the plug when it is inserted.
