OnStar. It is a subsidiary of the General Motors corporation, providing subscription-based telematics and in-vehicle safety and security services. The system offers features such as automatic crash response, emergency services, stolen vehicle assistance, and turn-by-turn navigation. Initially launched as a venture between GM, Electronic Data Systems, and Hughes Electronics, it has become a pioneer and major player in the connected car industry.

History

The concept was developed in the mid-1990s, with a formal announcement made at the 1995 Chicago Auto Show. The service officially launched in 1996 on the 1997 Cadillac DeVille, Cadillac Seville, and Cadillac Eldorado models. Early technology relied heavily on analog cellular networks and the Global Positioning System. A significant early partnership was with the Ad Council to promote vehicle safety. Following the acquisition of Hughes Electronics by News Corporation, GM assumed full ownership. Key milestones include the introduction of the first built-in vehicle telematics system and the expansion of services following the September 11 attacks, which increased public focus on security. The platform transitioned to digital CDMA and later 4G LTE networks, with its operations currently based in the Renaissance Center in Detroit.

Services

Core offerings are divided into safety, security, and connectivity packages. The flagship service is Automatic Crash Response, which uses sensors to detect collisions and connects occupants to an OnStar Advisor at a Public Safety Answering Point. Other safety features include Emergency Services, which can manually connect to 911, and Crisis Assist, activated during events like Hurricane Katrina. Security services encompass Stolen Vehicle Assistance, where advisors can work with law enforcement to locate a vehicle, and Remote Ignition Block. Connectivity services provide hands-free calling, Turn-by-turn navigation, and Remote Diagnostics, which can monitor engine health and schedule service at a GM dealership. A mobile application allows for remote functions like door unlocking.

Technology

The system's architecture integrates several hardware and software components embedded within a vehicle. The core hardware includes a Telematics Control Unit containing a GPS receiver, a cellular modem, and a backup battery. This unit communicates with the vehicle's Controller Area Network bus to access data from the engine control unit and other sensors. For communication, it utilizes embedded SIM cards to connect to mobile networks, originally operated by Verizon Wireless and later AT&T. Voice recognition software processes user commands, while data is transmitted to secure data centers for processing. The transition to 5G technology is part of ongoing development to support future applications like vehicle-to-everything communication.

Vehicle integration

The service is a standard feature on nearly all new General Motors vehicles sold in North America, including brands like Chevrolet, GMC, Buick, and Cadillac. Integration is deeply embedded into the vehicle's electrical architecture, often interfacing with the infotainment system such as GM's MyLink or subsequent systems. This allows for seamless activation of services through dedicated buttons, voice commands, or touchscreen interfaces. The technology is also offered as a retrofit module for some older GM vehicles. Beyond GM, the technology was licensed for a period to other manufacturers, including Audi, Subaru, and Volkswagen, though many have since developed their own platforms or partnered with other providers like Harman International.

Privacy and data collection

The service collects extensive data from enrolled vehicles, including location, speed, odometer readings, diagnostic information, and crash data. This data is governed by a detailed privacy policy and is used for service delivery, product improvement, and, with customer consent, for developing usage-based insurance programs. The system has been subject to scrutiny and legal challenges, including a class-action lawsuit regarding the collection of location data after subscription cancellation, which was settled in California. Concerns have also been raised about the potential for data access by government agencies under laws like the USA PATRIOT Act.

Competitors and market position

As a first-mover, it initially dominated the telematics market in North America. Major competitors now include Ford Motor Company's Ford Sync, Toyota's Safety Connect, BMW's BMW Assist, and Mercedes-Benz's mbrace. The broader competitive landscape also includes aftermarket devices from companies like Garmin and TomTom, as well as technology giants such as Google with its Android Automotive OS and Apple with CarPlay integration. The company maintains a strong market position due to its deep integration with the GM fleet and established brand recognition in safety, though it faces pressure from both traditional automakers and new software-defined vehicle platforms.
