As said, rerouting is a good feature of Google Maps, but sometimes it will take you to drive through narrow, bad roads. So, if you do not want to reroute when navigating to a particular place using Google Maps, and want to stay on the original route, follow this trick. Google Maps has no built-in option to disable rerouting. The only solution currently you can take on this is downloading your required route map, so it’s available offline.
How to stop or disable Google Maps rerouting you
Since there’s no internet connection, the Google Maps app will be unable to update, preventing rerouting from taking place. Google Maps is an excellent turn-by-turn navigation app for every smartphone user. Voice guidance, offline navigation, real-time location sharing, indoor maps of buildings, real-time train and bus departures, the walking option with live view, etc., are the key features of the latest version of Google Maps.
