The cubby hole, vents, and trip/ clock display all come out as one unit (if it's the same as the unit in my 04 Outback - pretty sure it is). I removed mine by gently pulling at the cubby hole/ lid until it started to move forward, then working around the edge gently pulling til all the clips came out.
The stereo is a little more involved:
1- remove the rear half of the centre console by taking the 2 screws out of the console storage box and then prising the unit upwards (there's a couple of big clips located where the console joins the gear shift bit.)
2- remove the gear lever (or shifter) surround - should just be clips.
3- Remove the two trim pieces that run either side of the stereo unit - they have a screw each right down the bottom below the gear shift, and then three clips each up the sides. Just take the screws out and then pull them gently towards the back of the car.
4- You should then see the screws retaining the audio system in place. Four are towards the front (2 either side) and two are located deeper back, about half way up each side of the unit.
when pulling it out, be careful not to strain the various wires plugged in the back, especially the grey antenna lead to the left of the unit.
hope that helps!
