Flip open the centre armrest box (open the bottom one) to get it out of the way.
The wood bit (together with the plastic cupholder and stuff) is clipped in, it pulls upwards, then slides towards the back of the car. The ashtray's also clipped to it, but this can be taken off afterwards.
As soon as it's pulled up, reach under and unplug the VSC, seat heat and ECT switches. When sliding out, reach behind and unplug the ashtray. Oh, and put it into gear or you won't get it out.
