Google Maps Plus Codes work by converting location coordinates (latitude and longitude) to alphanumeric codes that use a standardized format. They use an alphanumeric grid (like a chess board with a grid of A - H and 1 - 8) to divide the world. That first grid forms the first 2 numbers of the code.

North, South, East, and West are the four main "cardinal" directions. On a map, North is at the top, South at the bottom, West to the left, and East to the right. Every map has a Map Scale which relates distance on the map to the world.

Sometimes voice directions aren't downloaded or must be updated on your phone or tablet. When this happens, you'll hear a chime instead of voice directions. Make sure you're connected to the internet. If you have a strong internet connection, voice directions will download faster.

There are a few possible reasons why Google Maps might have shown your location in the incorrect place. Your location settings may be incorrect. Make sure that your location services are turned on and that you are giving Google Maps permission to access your location. You can also try restarting your device.
