I have the same router. The metal ring in the center of the plastic sub base is the pc template guide adapter. It can be removed for larger bits, but is allready installed on the base when you get it. Pics are of my plunge base but fixed base is the same.

I use this router with my Porter Cable dovetail jig. And can use either the guide that came with the jig or a brass one of the same size.
