While I love CarPlay for most of the stuff, I hate navigation from Google Maps or Waze / phone. I'm not sure if it's placebo, or something else, but for my car, the navigation is just better, especially when driving in tunnels and other weak GPS areas. The car system seems to use more than just GPS, like speed, direction and distance and even if you drive in a long tunnel or other similar conditions, it just knows not to mess up the position of the car, miss exits and other things. I know it depends on the manufacturer, but I get regular OTA updates for the navigation, live traffic updates that are quite good, dangerous situations on the road ahead and so on.
