OnStar is a satellite-based communications system developed by General Motors. It provides access to a range of subscription-based services, including navigation, roadside assistance, anti-theft, emergency response, and concierge. The OnStar system is available on 2015 and newer GM vehicles and via the OnStar Guardian smartphone app, accessible in any vehicle, on a motorcycle, in-home, and beyond.
The OnStar service began as a luxury feature from GM. Its non-emergency features include hands-free calling to anyone using an AT&T (previously Verizon) mobile account and navigation assistance. Navigation assistance can range from built-in GPS features to the option to contact a concierge for information about local restaurants or traffic conditions.
Roadside assistance is a significant component of OnStar service. Service representatives can dispatch towing and emergency crews when the car breaks down or is in an accident. OnStar activates automatically on many vehicles when their airbags deploy, allowing a representative to contact the driver and send emergency response crews if the driver cannot respond.
Several anti-theft features are relatively new to OnStar. Early models included GPS tracking designed to help locate a stolen vehicle. Recent developments added an engine-throttling device to reduce a vehicle’s speed and even bring it to a stop on demand. Interlock ignition switches can prevent the engine from starting when OnStar security features are active.
