As an example- new Volvos come with Android Automotive as the main OS, and the satnav is just Google Maps. There is no alternative built in. If you don't want google services then you have no satnav at all. Since the main instrument cluster also shows Google Maps if you disable it it just stays completely empty(only displaying basic information like speed and gear you're in).
