The inserts if there, have a slot in each one, you can use a screwdriver to unlock them. Mine had a very thin black rubber pad in the bottom of the cupholder hiding them. Make sure its not underneath those pads.
If manual trans, there's two screws that you should be able to see the holes while your driving. pull those screws(phillips), and pop off the shift boot at the base off it's clips. After that, you should be good to go.
