General Motors has created an API-accessible application development platform for their vehicles. This platform is accessible through an in-vehicle API and a remote API.
The GM In-Vehicle API supports development of applications that interface directly with GM vehicles and their systems through the infotainment system. The GM infotainment system provides connected-car functions by linking to a driverâ€™s smartphone.
API methods include access to vehicle information, I/O commands, communication capabilities, audio and video playback, navigation, phone systems, user interface, and infotainment system commands and utilities.
