Google-owned mapping app Waze was updated to version 18.104.22.168 which brings support for CarPlay on devices running iOS 12. With iOS 12 Apple allows third-party mapping apps to be used with CarPlay for the first time, providing an alternative to the built-in Apple Maps app.
Waze is a popular app because it provides detailed information on traffic, ongoing construction, crashes, and other issues that can result in travel delays. You can download the update directly on your iOS device through the Apple App Store or by using the following link.
Google Maps for iOS version 5.0 was also recently released with support for iOS 12 and CarPlay.
