GM is killing Both carplay and AA, everyone is confused all over the place and reporting is awful.

The new system runs off "Google Automotive Services" (AKA: GAS - Native Google Android on the car's computer hardware) complete with the Play Store. Apple could always build iMessage and Apple Maps for GAS.

The same thing that stops Apple from making their phones USB-C compatible, or iMessage RCS compatible, or making the app store back-end not require xCode and a mac merely to upload a file. They are a monopoly, and they are trying to coerce consumers to give them more money.
