hi mate..first get masking tape and tape off the sides of the dash(you dont wanna scratch your dash)
the top tray just pulls off(pull it towards you) then pull the pannel with the trc buttons on it towards you now you will see two 10mm bolts at the top and two at the bottom remove these and pull the stereo and the heater controls out(they are joined together with screws and a frame either side)remove the screws and the stereo and the heater controls will seperate now rebuilding is the same as removal.
hope that helps.
