Type your address and pick it from the list. The pin moves there. If your exact address is not listed, type as much as you can (for example Cameroon, Douala, Bonaberi), then drag the pin to the right spot.
Exact spot code
This code points at the exact spot you pinned. Google Maps understands it. Write it down, or give it to a driver, and it brings them back to this same place.
Tap the map to place a pin, or drag the pin to adjust it.
