Was trying to figure this out myself. After looking at the Car Play website, it doesn't seem like they do, which is annoying.
I'm assuming that Apple isn't playing nice with Google and giving users free choice about which nav apps they can use and that Google would release a Google Maps and/or Waze version for Car Play if given the ability.
Again, these are assumptions, if anybody can correct me on that, I'd love to hear otherwise.
This to me is a big enough deal that I would seriously consider an Android over an iPhone for this reason alone. I never use Apple Maps, it's an inferior product on every level, and I can't understand why Apple seems insistent on the idea that people want to use it. In my experience the only people who use Apple Maps are those who are too lazy to change from the default nav system built into the iPhone or just don't care enough to use a better nav system. It's never people who actively prefer Apple Maps.
Google Play Music works just fine in CarPlay, but currently Apple only allows music and messaging apps. We don't know why Apple doesn't't allow navigation apps but its not because they are pushing Google out.

Luckily, iOS 11 has brought / is bringing lane-guidance to Apple maps. This is a huge deal for me and makes maps.app a lot more tolerable and driver-friendly.
