All you need to know about onstar

What Is OnStar?

OnStar Corporation is a subsidiary of General Motors that provides subscription-based communications, in-vehicle security, emergency services, hands-free calling, turn-by-turn navigation, and remote diagnostics systems throughout the United States, Canada, China, Mexico, Europe, Brazil, and Argentina.

How Does It Work?

By gathering information through your vehicles’ on-board diagnostics system, along with GPS data. It also utilizes cellular technology for voice communication and data transmissions.

The OnStar service allows users to contact OnStar call centers during an emergency. In the event of a collision, detected by airbag deployment or other sensors, Advanced Automatic Collision Notification features can automatically send information about the vehicle’s condition and GPS location to OnStar call centers. OnStar has 24-hour emergency call centers. This Advanced Automatic Collision Notification service is designed to assist emergency response efforts.

All OnStar-equipped vehicles have Stolen Vehicle Tracking, which can provide the police with the vehicle’s exact location, speed, and direction of movement.

Starting in the 2009 model year, General Motors began equipping some new vehicles with Stolen Vehicle Slowdown. This feature allows OnStar to remotely slow down the stolen vehicle. Also in 2009, General Motors began equipping some new vehicles with Remote Ignition Block, allowing OnStar to remotely deactivate the ignition so when the stolen vehicle is shut off, it cannot be restarted.
