Before iOS 12, Apple Maps was the only mapping app you could run on the dashboard in a CarPlay-equipped automobile. But Apple Maps doesn’t always work well, and some people prefer directions from Google Maps or the Google-owned Waze. Once you upgrade your iPhone to iOS 12 and update to the latest version of Google Maps or Waze for iOS, you’ll be able to use those apps on your CarPlay screen.
Personally, Waze is my favorite for driving in Washington DC because it can easily navigate our complex rules regarding time of day turn restrictions and Rock Creek Parkway’s rush hour reversal.
If you want to rearrange your CarPlay icons to move Waze or Google Maps to the first screen on your car display, open your iPhone Settings app > General > CarPlay, then tap on your car. Each car has different settings.
