You need to use a FOB to access the navigation computer

You need to use a FOB to access the navigation computer is a quest in Fallout 2.

Detailed walkthrough
The tanker FOB is located at the Enclave base of Navarro in the commander's office.

The player character needs to get into the commander's office any way they can, which leaves four options:
 * Use force to gain entry.
 * Sneak.
 * Lie to the guard and walk in posing as the cleaning crew (requires high Speech or low Intelligence).
 * Lie to the guard about having to acquire the tanker FOB in order to disable the PMV Valdez (requires high Speech).

The last option allows the Chosen One to retrieve the tanker FOB from the locker without any resistance. All other options require stealing the tanker FOB from the locker, making the entire base hostile if detected.

Afterward, head to the tanker in San Francisco. Go to the lower level of the tanker, and use it to open the door. This will allow the questline to continue.

Rewards

 * 5000 XP
