Its easy but cover the wood etc with a reasonably thick bit of cloth!!!!!!!!!

First remove ashtray and just pull out the unit will need a bit of force but will clip out. This will reveal three screws come bolt heads 8mm I think. take them out

Second get hold of the air vents at the top and again pull them out they will come but use fingers not a tool.
Behind this are 2 screws as above , take them out and the radio/heating unit comes out, this can then be seperated from its two brackets either side by removing more screws.

You will have to disconect various wiring plugs but no problem, they all come off and are colour coded.

Easy peasy put it back together the opposite way.
