I just installed the Jeep Trail Guide last weekend and had to remove the dash as well. Never doing it before it was trial and error for me...........
On the top center portion (above the radio), take a flat head screwdriver and press in on the back left and back right sides and the top portion of the dash will pop off. You will see two screws, remove them.
On the bottom flat panel right behind the gear shift and below the five buttons, do the same thing and remove the two screws.
Slowly work from the top and pull the dash off. Be aware, the dash only comes off a few inches due to all the wiring.
