Craft a navigation module | 7: Mayhem Dead Space 3 Guide

The only way to construct a navigation module is using the workbench. The nearest one is located on the C.M.S. Roanoke. Use the locator to find the ship entrance. Try to monitor your oxygen level - if you haven't use containers, you might get short on oxygen.

Once you get inside, go to the right, passing by suit kiosk. Finally you'll reach the room with the workbench. When you activate the bench, information about crafting the required module will be shown. Now it is enough to install it.
