Does the Car Play also include Waze functionality? I have a 2018 Traverse and just noticed that it does work through CarPlay. It's a MUCH better system that the darn GM imbedded one that doesn't;t include MAJOR updates and configuration changes to major highways that were done over 3 years ago.
Hi Ragnar51,
Yes, the Waze iPhone app works well with CarPlay. I alternate between Waze, Google Maps, and Apple Maps for navigation in my '18 Subaru Outback with CarPlay. I prefer any of them to the Outback's own navigation system.
To activate Waze with CarPlay, on your iPhone go to Settings > General > CarPlay, then drag the Waze app icon on to the virtual CarPlay screen. Next time you plug your phone into your car, it'll be there.
If you're not seeing the Waze icon in CarPlay settings, make sure you've updated to the latest iOS and Waze versions. If you have and it's still not there, then maybe post a new item in the iOS 12 forums about your problem, and you'll get suggestions from people who know this stuff a lot better than me.
Good luck!
