[1] Apple gives the car manufacturer the ability to truncate the length of scrollable lists while the car is in motion, which Mazda does. Nothing like only being able to see the first 15 items in a list of podcasts, or artists, or songs. I hate this. But otherwise the implementation is great, especially the integration between the car's physical controls and CarPlay. There's a steering wheel button to bring up Siri. There's direct physical button access to Maps, Now Playing, and the home screen. It would be nice if Apple allowed me to set Google Maps as the default mapping app, but Apple maps has become good enough most of the time. Aside, my 2016 CX-9 came w/o CarPlay. Mazda made it available as a DIY'able retrofit last year. The parts were a couple hundred dollars and it took a couple hours to retrofit.
[2] Once the entire entertainment system froze up and it didn't fix itself till like the next day. I've been meaning to check if there's an update from Chevy.
