take off the dash facia which is around the original headunit. There are two screws on the beam below the heater controls. Once you have done that gently prise the bottom of the facia away from the dash (it is clipped on), once you have done this you will have a clear view of the headunit and the surrounding area. The is another 4 screws that you will then need to remove. The hold the metal bracket onto the dash, which also holds the headunit in place. There is two screws above, and two screws below, that are a little harder to acces. Once you have done that the whole head unit and bracket will come out, discounect all the wires, and then your free. I think the head unit is screwed into the bracket so there will be a few more screws. Simply undo these, and the headunit will come out of the bracket. simply re-install the new headunit, using the pointers you used to take it out Hope this helps. Thats all i can remeber when i helped do it....... Rob
