Is it by updating the software in your car? Or by updating the iOS on your phone?
null-OTHER, iOS 10.2.1, CarPlay
There isn't any separate button to update Carplay. But according to Apple's next seed iOS 10.3 Public beta. A tiny update will available for Carplay, that the quick access to albums from songs in Music, new Up Next screen. So you will have to wait until Apple iOS 10.3 Public release. 🙂🙂
The answer in some ways is "both," but the main way to update CarPlay is to update iOS on your phone.
However, there may be some features of CarPlay that your current car software doesn't support. For example, I've read that CarPlay at iOS 10 supports showing turn-by-turn directions in instrument cluster displays, but my car doesn't seem to support that. I'm hoping that feature comes in a future update to my car's software.

You would think Apple would do a better job of making this clearer or easier to find.
How does CarPlay update?
