Apple has also reached out to developers of CarPlay Apps for two different things. The first thing is CarPlay with AirPlay for streaming services so this will be a feature / not sure if this already works, haven’t had the time to test it yet. And the other one is a new type of CarPlay app called Voice-Based Conversational. Which is intended for ChatGPT, Gemini, Grok and more, to have their voice modes accessible through CarPlay.
