u need to go under your dash on drivers side and find the cable attached tot he centre box and unclip it, then when you remove the centre surround, u unplug the dimister and hazard switch and the complete unit will pull out
^ That. You have to take out the black fascia/surround and unclip the cable from the box, then when you pull it out (after following mikeys instructions) you can pop out the vents from the surround. Try not to break the clips of the air vents otherwise they will no longer be stiff and will jiggle around and be very loose (but they won't fall out).
