iPhone users in the European Union can now set Google Maps as their default navigation app, moving away from Apple Maps. This change comes as part of the European Union's push for greater app customization, allowing users to choose their preferred navigation tools. The update is included in the upcoming iOS 18.4 release, which also enables users to select default apps for emails, web browsing, and messaging. To set Google Maps as the default, users must update the app and adjust their settings accordingly. This feature empowers EU users with more navigation options.
