door trims - two screws in the handle, unscrew em
- use a flathead screw driver to lever off the surround of the door opening mechanism
- use a small flathead screw driver or something simular and get between the window winder and the door and push the metal clip out (first time will be hard after that it'll take you no time at all).
- pop out all the clips around the door trim (they come out pretty easy just give em a tug)
- push the door trim up so that it is no longer attached to the door in anyway.
radio - remove the surrounding panel (theres about 8 or so screws holding it in place (2 behind the ash tray)
- there are 4 screws holding the metal mounting bracket in place, undo them
- unscrew the radio from the mounting bracket
- start cutting wires. dont cut the airiel wire (thick black one) just pull the plug out the back
hope that helps
