OK, so when you enter a route on Waze via your phone, what does Waze on the in car display show?
If you have Waze up on the car's display, it shows Waze's map and the most immediate next turn, ETA, etc. See the 2nd screenshot at
Apple CarPlay. On the phone, if Waze is up, it'll show more directions + other UI.
Long ago, Apple unlinked what was shown on each screen (previously, they were coupled). For years, you can have Apple Maps up on the car LCD while Waze is giving you directions. You could have the full screen audio player controls up on the LCD or something else.
How about when you're playing something on Spotify or Apple Music on your phone, what does the media player on the in car display show?
It can show whatever you whatever CarPlay app can render on the car's LCD.
I'll give you a hint, it's the exact same thing the phone is showing - i.e. it's screen mirroring. The fact it lets you open up different apps doesn't take away from the fact it's still screen mirroring.
It isn't showing the same thing as what the phone's showing at all. They don't even need to be the same app. The orientation is different. The content on each is different. What's allowed on the car's LCD are large controls and a very limited set. Numerous things aren't allowed (see pages 5 to 9 of
https://developer.apple.com/carplay/documentation/CarPlay-App-Programming-Guide.pdf).
If you bring up the Messages app on CarPlay, you can't physically read it on the car's screen. It's totally different from Messages app your phone. It can dictate it to you and has very simplified UI on the car side.
Almost ALL iPhone apps do NOT support CarPlay.
Other than CarPlay apps from automakers, the only allowed app types for CarPlay are on pages 3 and 11. For instance, there's no YouTube or any video playback at all on the car's LCD. It's not allowed. If it were technically possible, Apple would reject the app or remove it if somehow a dev snuck it in.
In the 2nd video, at the beginning, I was using the NPR app (not NPR One). It doesn't support CarPlay at all. There is no CarPlay UI other than the generic media controls which aren't NPR specific.
Next you'll be arguing that because the car display shows everything in landscape and your phone is in portrait it's definitive proof it's not screen mirroring
LOL!
If you want to see screen mirroring, plug
Lightning Digital AV Adapter - Lightning to HDMI into an iPhone then into an HDMI TV or monitor. I have several of these dongles for work (and it does relate to my work). So, I don't have to repeat the work that others have done, this is an example I quickly found. Go to 0:50:
.
Or. skip to 0:28 of
. There are exceptions to the by default mirroring w/this dongle. When playing videos, it could be mirrored or there could be a set of controls on the iDevice but the video playing on the TV or the developer can block it.
