The upcoming iOS 18.4 update introduces an option to set a default navigation app, other than Apple Maps, but unfortunately this new setting is limited to users in the EU. There, you can now set an app like Google Maps or Waze as your default navigation app on the iPhone by opening the Settings app and tapping Apps → Default Apps → Navigation.
Apple made this change in response to the EU’s Digital Markets Act.
This one seems kind of spiteful. I get that Apple doesn’t want to make sideloading available throughout the world just because the EU and Brazil have mandated it, but they’re going to hide the very useful maps setting in countries that don’t have a DMA?
