Presumably related to: GM plans to phase out CarPlay in EVs, with Google’s help https://news.ycombinator.com/item?id=35389021 (38 days ago, 377 comments)
There are three current solutions -
- (2018 -> Today) Some existing solution that runs QNX as the base OS, that runs Android Auto / Carplay as an Application
- (2023 - > Today) A new based OS that is a skinned version of Android Automotive OS (AAOS / https://developers.google.com/cars/design/automotive-os) that runs both Android Auto Carplay and Carplay as an application, with the Automaker working with Google to incorporate customizations along with patches and updates to the base OS. Think Samsung's customized version of Android, and how they work to implement patches for major OS updates from ASOP. The infotainment used on General Motor's Global B architecture uses this.
- This proposal (2025 Model Year -> Future) - runs a customized version of AAOS that does not have Android Auto / Carplay support. My guess is that Google is throwing them a bone here and offering extra support for the Automaker (deferring the Automaker's costs) if the Automaker allows Google to retain the usage data.
