I understand how the communication bus contains all the info that is displayed, but where does the car’s display start and end and what does CarPlay add to it? Is it just a framework for the graphics?
Going forward, for the car brands that support it, much of the cars performance data and 'optional' controls are funneled to the iPhone, which then take over multiple displays within the car -including the instrument cluster.
The difference is that current CarPlay runs on the entertainment portion of the car, future CarPlay takes over the instrument cluster for speed/performance info display and other car functions like taking over the heat/cooling controls, etc.
In the event CarPlay is not in use, the car has a default set of display stuff.

That would include receiving data.But how is a cell phone able to generate enough energy for a signal all the way back to a satellite?If you look at the transition from 4G to 5G and the density of antennas needed to render service, it’s a far cry to space…
