If you are referring to the display, you need to remove the long trim covering the Air Con controls, this exposes the two screws retaining the vents. Behind the vents are two further screws retaining the front of the display, along with the two you have already found... Before the long trim can be removed, you need to remove the panel covering the ignition switch.
My display is really noisy on closure, but fine opening. I haven't yet plucked up the courage to pull the dash to pieces :?
If you can wait until tomorrow night I can provide the relevant details/diagrams from ISTA/D.
