Removal of the OEM stereo is simple. Start at the bottom of the center console, where the two outlets are and carefully start pulling. It will start popping off. There are four screws that hold the stereo in. The wiring harness is the same for nissan's 95 and up. Just becareful of the sirbag sensor. I installed a Kenwood DDX7015 dvd/navigation headunit about two months ago. Piece of cake!
