Mark's smoothed 306 with added extras.

Pull the bottom panel off. Unscrew the clock and the two screws. Pull the radio out, either side of the radio is a nut behind the panel. Undo these.

Pull the middle panel out. Then below the top vents are two or three screws. Undo these, then you just need to pull, the vents clip to the pipes behind so you just need to make sure you unclip them as you pull.

Lol I have just written all that and realised that is not what you asked. To get the middle vents out, there are two circular clips, ping these off with a knife. I the pulled the house away from the centre vents and popped them out the front. They go in easier from the back of the housing though.

Mine are wrapped in the same vinyl as the car.

Haha yeah was more for the vents bit . haha. Sweet, so wrapped in same as car, looks good mate!!

You could read the guide section as I showed how to remove it with added pics! Lol
