You take the side panels of the dash off. Where the air vents into the door. there should be 3 or 4 screws, I forget, but one is hidden in the air vent. Take that off, then there is one screw holding the top dash trim panel, unscrew that then pull the panel out. You'll understand when you do it.
Page 8 of this has the side panels and page 10 has the top trim panels.
