OnStar: GM’s Connected Services Explained
For three decades, OnStar has evolved from a pioneering emergency-response service into a broad connected-vehicle platform that supports safety, convenience, connectivity, entertainment, navigation, and advanced driving technologies. What began with a simple idea — giving drivers a way to get help when they need it most — has become an important part of the connected experience across Buick, Cadillac, Chevrolet, and GMC vehicles.
The familiar blue OnStar button remains a recognizable feature inside many GM vehicles, but today’s system can do considerably more than contact an advisor after a crash. Depending on the vehicle, subscription plan, and available technology, drivers can use OnStar services to remotely control vehicle functions, monitor vehicle information, connect devices to the internet, receive navigation assistance, and support advanced driving systems.
OnStar also extends beyond the vehicle itself. Many connected services can be accessed through the MyBuick, MyCadillac, MyChevrolet, and MyGMC mobile applications, allowing owners to interact with their vehicles from virtually anywhere with a smartphone.
As OnStar marks its 30th anniversary, its expanding capabilities illustrate how connected services have become increasingly integrated into the modern driving experience.
Safety Remains at the Core of OnStar
Safety has been central to OnStar since its introduction. The service is designed to provide assistance in situations ranging from serious crashes to everyday roadside problems.
One of its best-known capabilities is Automatic Crash Response. Following a qualifying collision, OnStar can automatically connect with an advisor. The system can use information from the vehicle to help determine that a crash has occurred and provide relevant information to emergency responders. This can be particularly important when occupants are unable to make a call themselves.
Roadside Assistance is another important service. Drivers dealing with problems such as a flat tire, dead battery, or mechanical issue can request assistance. Depending on the circumstances and coverage, OnStar can help arrange services such as towing and send assistance to the vehicle’s location.
OnStar also offers Stolen Vehicle Assistance. When a vehicle is reported stolen, OnStar can work with law enforcement to help locate it. Certain vehicles and circumstances may also support technologies designed to assist authorities in slowing or stopping a stolen vehicle.
For emergencies, drivers can press the red emergency button to connect with a 24/7 Emergency Advisor. Advisors can help assess the situation and coordinate emergency assistance when necessary.
Another feature is Crisis Assist, which can provide assistance during severe weather events and other emergencies. Depending on the situation, connected services can provide information and help drivers navigate around affected areas.
These capabilities demonstrate how connected technology can provide assistance beyond traditional vehicle functions.
Remote Vehicle Commands Add Everyday Convenience
Not every OnStar feature involves an emergency. Many of the service’s capabilities are designed simply to make everyday vehicle ownership easier.
Through compatible vehicle apps, owners can remotely lock and unlock their vehicles. This can be useful when someone realizes they forgot to lock the doors after leaving the vehicle or needs to provide temporary access to another person.
The same connected system can also allow drivers to sound the horn or flash the lights remotely. This can help locate a vehicle in a crowded parking lot.
For compatible vehicles, remote start allows drivers to start the engine from a distance and prepare the cabin before getting inside. Depending on the vehicle, remote controls can also help manage cabin temperature. Electric vehicle owners may have additional remote charging controls, including the ability to start or stop charging.
Another useful function is sending directions to the vehicle. Drivers can select a destination through the appropriate mobile application and send it to the vehicle’s navigation system before beginning a trip. This can save time when a destination is known in advance.
Vehicle information can also be viewed remotely. Depending on the model, owners may be able to check fuel level, battery charge, tire pressures, odometer readings, oil life, and EV charging status.
The vehicle’s location can also be displayed through the mobile app, making it easier to remember where the car was parked.
Connected Services Keep Drivers Online
Modern vehicles increasingly function as connected devices, and OnStar provides several services designed to keep occupants connected while traveling.
One major feature is the in-vehicle Wi-Fi hotspot. Compatible vehicles can provide internet connectivity for passengers and other devices. Depending on the service and vehicle configuration, the hotspot can support multiple connected devices and extend connectivity beyond the immediate vehicle cabin.
This can be particularly useful during family road trips, camping trips, or situations where passengers need internet access while traveling.
OnStar also supports connected navigation services. Live traffic information can help drivers understand current road conditions and select routes based on changing traffic conditions. Built-in navigation can also help drivers identify destinations and plan trips.
GM is also bringing artificial intelligence into compatible vehicles. Vehicles equipped with Google built-in can support Google Gemini, providing an AI assistant that can respond to natural-language requests. Instead of relying exclusively on rigid voice commands, drivers can interact using more conversational language.
Depending on vehicle capabilities and available services, AI assistance can help with tasks such as adjusting the cabin environment or planning routes. The technology represents another step toward making vehicle interfaces more conversational.
Over-the-Air Updates Keep Vehicles Current
Connected vehicles can also receive software improvements without requiring every update to be installed at a dealership.
Over-the-air updates can deliver software changes, refinements, and, where supported, new vehicle features directly to compatible vehicles. These updates can help keep vehicle systems current while the vehicle is parked.
The broader move toward software-defined vehicles means software is becoming an increasingly important part of vehicle ownership. Instead of a vehicle’s capabilities being completely fixed when it leaves the factory, connected systems can allow manufacturers to improve and update certain functions throughout the vehicle’s lifecycle.
Entertainment for Drivers and Passengers
Connected vehicle technology is not limited to safety and utility. OnStar services can also provide entertainment options for passengers.
Compatible vehicles can offer access to audio streaming, including music, podcasts, audiobooks, and news. These services can provide additional entertainment during daily commutes or longer road trips.
Connected services can also deliver news updates through the vehicle’s infotainment system, allowing occupants to stay informed while traveling.
Some compatible infotainment systems support video streaming, giving passengers access to movies and television programs. This can be particularly useful during longer journeys when passengers need additional entertainment.
Games can provide another option for passengers, ranging from short activities to entertainment designed for longer trips.
An internet browser may also be available in compatible vehicles, allowing users to access web content directly through the vehicle’s infotainment system.
The availability of these entertainment features can vary according to vehicle model, equipment, software, subscription plan, and market.
OnStar and Advanced Driver Assistance
OnStar also plays a role in supporting GM’s advanced driver assistance technologies, particularly Super Cruise.
Super Cruise is GM’s hands-free advanced driver assistance system for compatible roads and vehicles. One important part of the technology is access to detailed map information. OnStar connectivity helps deliver updated map data so compatible vehicles can identify roads where Super Cruise is designed to operate.
This means connected services can contribute to the operation of technologies that go beyond traditional infotainment and convenience features.
Certain GM trucks and SUVs equipped with Super Cruise can also support hands-free trailering. The system can account for the presence and length of a trailer when assisting with driving on compatible roads.
Other Super Cruise capabilities include turn signal-activated lane changes. When the driver activates a turn signal, the system can look for an appropriate opening and assist with the lane change when conditions permit.
Compatible vehicles may also offer automatic lane changes, allowing the system to assist with passing slower vehicles under appropriate conditions.
These systems remain driver-assistance technologies rather than replacements for an attentive driver. Drivers are expected to monitor the road and vehicle operation and remain responsible for the driving task.
OnStar Has Expanded Far Beyond Its Original Purpose
OnStar’s 30-year history illustrates how dramatically vehicle connectivity has changed.
The original appeal of OnStar centered heavily on emergency assistance and the ability to connect drivers with help. Today, that safety foundation remains important, but connected services have expanded into numerous areas of vehicle ownership.
A single platform can now combine emergency response, roadside assistance, stolen-vehicle support, remote vehicle controls, navigation, Wi-Fi connectivity, software updates, entertainment, mobile applications, and support for advanced driving technologies.
The mobile applications further extend that experience beyond the vehicle. Through MyBuick, MyCadillac, MyChevrolet, and MyGMC, compatible vehicle owners can access various connected functions using their smartphones.
OnStar Plans and Availability
Every new Buick, Cadillac, Chevrolet, and GMC vehicle comes with an OnStar trial, allowing customers to experience connected services before deciding which services they want to continue using.
GM offers several OnStar plans, including Connect, Connect Plus, Protect, and Super Cruise, with the exact features depending on the vehicle and subscription.
Pricing can vary based on the plan and available services. The plans are designed to give drivers different combinations of connectivity, safety, convenience, and advanced driving capabilities.
It is also important to note that not every OnStar feature is available on every GM vehicle. Equipment, model year, software, geographic location, subscription status, and vehicle compatibility can affect which services a customer can use.
The Future of Connected Driving
The evolution of OnStar reflects a broader transformation taking place throughout the automotive industry. Vehicles are increasingly becoming connected computing platforms, with software, cloud services, mobile applications, artificial intelligence, and digital infrastructure working together.
For drivers, that means many vehicle functions no longer end when the ignition is switched off. A smartphone can provide access to vehicle information, remote commands, navigation preparation, and other services from outside the vehicle.
At the same time, technologies such as Automatic Crash Response and emergency assistance demonstrate how connectivity can be used for critical situations. Advanced driver assistance systems such as Super Cruise show another dimension, where connected data and software contribute to the operation of sophisticated driving technologies.
After 30 years, OnStar has therefore become much more than the blue emergency button that introduced many drivers to connected vehicles. Its role now spans safety, convenience, communication, entertainment, navigation, vehicle management, and advanced driving support.
As GM continues developing connected and software-enabled vehicles, OnStar is positioned as an important link between the vehicle, its occupants, smartphone applications, cloud-based services, and the broader digital ecosystem surrounding modern transportation.
