Apple CarPlay is automotive integration software that allows users to interact with supported applications for audio streaming, communication and, of course, navigation on the dashboard displays of compatible cars.

Apple announced that iOS 12 would bring third-party navigation support to Apple CarPlay and briefly displayed CarPlay's dashboard interface with new icons for Waze, Google Maps and Chinese navigation app Autonavi Navigation. It's unclear whether these will be the only apps supported, but that's a solid third-party starting roster.
