Thanks to iOS 13.4, Apple CarPlay gets third-party map integration in the dashboard. Apple's in-car interface supports different apps on its dashboard to work side by side. But for navigation, Apple Maps was your only option until this update appeared. Now, apps like Google Maps and Waze can be used on the dashboard's split-screen option.
Apple has been working on improving its own Maps app, but a lot of people still prefer Google's options and other third-party map apps. This inclusion will help make CarPlay more useful to more users. iOS 13.4 also brings in-call information on the CarPlay dashboard.
