Basically, yes... There are a few how to's on dotted about the forum if you have a search.
You basically need a double din cage, which is an OE part and I believe it is still available from TPS. And you will also need different heater controls.
I'm sure I've got some more info and part numbers saved somewhere, I'll try dig em out for you this evening... Is it for a face-life or pre face-lift interior?
