Nissan Almera Standard Radio Removal

I am looking to remove my standard Nissan radio as I am getting major problems with it. I still have a decent system that I purchased for an old car that I am going to install.

I have got the fascia board that will take the new radio. The only thing is the wiring. The new radio has the standard ISO plug. I need to know which leads will help me connect this with the standard Nissan wiring? Also is it possible to connect the radio so that the steering wheel remote will work, I'm just so used to it now it would be a drag to miss it.
