The Nissan Armada is a full-size SUV built by Nissan Motor Company. The Armada was introduced in 2004. As of the 2010 year model, the Armada has not been redesigned. This tutorial will work for all models 2003 to 2010, regardless of the trim package. Removing your old stereo will allow you to upgrade it by installing a new one.
Park your Armada on a flat surface. Put the console gear shift in the neutral (N) position and turn the engine off. Make sure you engage your parking brake. The gear shift must be in neutral to remove the center panel. Pop the hood and unhook the negative battery cable.
Open the glove box door and remove the two screws (one on each side of the latch). Squeeze the outer tabs of the glove box to completely remove it.
Lower the ring around the gear shift and twist the gear shift knob counterclockwise to remove it. Remove the screw on the driver's side foot well panel (below the ignition).
Snap off the gear shift console panel. The panel is only attached by clips; it comes off easily with a little force. With the gear shift in neutral, you will be able to slide it right off. Wait until after the console is put back on before taking the gear shift out of neutral; it will not go on with the shifter in park (P).
Snap off the radio surround panel. The panel extends to the center air vents and a few inches on top of the dash. Once you have removed the panel, set it aside.
Remove the four stereo mounting screws and pull your stereo from the dash. Unhook the antenna cable and the factory wiring harness from the rear.
