I romoved my double din unit myself and put a standerd system in it, its a pain in the ***** and cables every where. but you start of at the gear box grab the plastic from the box and it will lift up, takethe gear nob off so you can get the cover off. Then you then see some screws where the climate control is, remove them to get to the head unit. There are some more screws they need removing and the unit should come out. If you are putting another unit in you may need a Jap to English cable convetion which you can get at halfords. Dave
