Removing Factory Head Unit

I need some help/advice on removing the factory Bose Head Unit in my 2002 Maxima. Any help would be appreciated.

just wondering why do you need to remove it?

Removing it can be tricky, but you will encounter another set of problems if you dont know how to rewire the existing system. The deck will turn on but you wont get any sound if you dont wire it right. I'm with zoemayne, why do you want to replace it? It's a great system and a nice head unit.
