Ford Bronco Overhead Console Compass Variation Zones Map & Zone Setting

This is a scanned page from a Ford service/owner's manual covering the electronic compass zone setting procedure (true north adjustment) for the overhead console compass. The page is partially cropped on the left, but the visible portion includes step 4 of the procedure: after setting the zone, release the MODE button and after a few seconds the display returns to normal compass heading mode, completing the true north adjustment. The main feature of the page is a "Compass Variation Zones" map (figure K14758-A) showing North America, Canada, the United States (with a Hawaii inset), and Mexico, divided into 15 numbered magnetic variation zones. The zone boundary lines radiate from the magnetic north pole region. A vehicle owner uses this map to determine which zone number (1 through 15) corresponds to their location, then enters that zone into the compass using the MODE button (partially visible instructions reference pressing a button until "VAR" appears on the overhead console and cycling the zone number with the MODE button). The page helps owners calibrate the compass so it reads true north accurately for their geographic region.
