This is the best summary I could come up with:

This has not sat well with every automaker; in March of this year, General Motors made headlines—and generated a lot of comments—when it announced it was killing off support for casting interfaces (both CarPlay and Android Auto) from its future products.

This little-known feature is only offered to OEMs and allows them freedom beyond the restrictive user interface guidelines laid down by Apple.

The app presents a series of tiles on the screen, configurable by the user, which allow you to change the climate settings, switch between favorited radio stations (AM, FM, and Sirius XM), or change the interior lighting.

The My Porsche App also integrates with Apple Maps and allows you to create favorite locations or local searches (for a coffee shop, for instance).

Although the freedom of the Automaker toolkit would have allowed Porsche to make the app look just like its native infotainment system, it didn't.

And again, the goal for us is that customers, when they're not in the car, they are using the iPhone, iPad, MacOS, Apple Watch, they are very familiar with this UX, UI.
