Write an article based on this "Open Google Maps on your iPhone or iPad. Tap the location button. Tap the compass icon. Find the "N" on the compass."
It's a map icon with a "G" and red pin, typically found on one of the home screens. It's the solid black circle inside a larger circle with crosshairs. It's near the bottom-right corner of the map. It's above the location button, and has one arrow tip and one white. The map will reposition so that the red arrow of the compass is facing north. You'll know it's pointing north because of the "N." The compass disappears quickly, so you may need to tap the location button and then the compass again to view the "N" and arrow.
