A NAV Table is a Buildable in Call of Duty: Black Ops II.
These are used for the "Tower of Babble," "High Maintenance," "Mined Games" Easter Eggs, and they are each built on TranZit, Die Rise, and Buried.
In "Tower of Babble," this must be built in order to advance to the next step, which either requires two Turbines to be placed on both sides of the table (Maxis path) or the Thrustodyne Aeronautics Model 23 to be overloaded (Richtofen path).
The "Mined Games" Easter Egg also requires all three tables to have NAV Cards inserted before the Easter Egg is complete, with either Ludvig Maxis or Edward Richtofen gaining control of the Aether, depending on which paths were taken in the three Easter Eggs prior (following Maxis 2 or 3 times will result in Maxis's control and following Richtofen 2 or 3 times will result in Richtofen's control).

The NAV Cards are set up as follows:
