What myGMC is for and who it suits

myGMC is the companion app for GMC vehicles. Its main job is to let an owner see and control the car from a phone, whether the owner is at home, at work or somewhere else.

It suits GMC owners who want remote access to their vehicle. The listing says the app needs a data connection, and that feature availability depends on the vehicle, the device and the plan the owner is enrolled in.

Remote start, lock, unlock and locating the vehicle

The app can start the vehicle remotely, and it can lock and unlock it from the phone. It can also show where the vehicle is, which helps when the car is parked somewhere unfamiliar.

These controls run over the same data connection as the rest of the app, so they depend on signal at both ends. The listing notes that exact functions vary by vehicle.

Vehicle health readings and cabin preparation

The app reports fuel level, tire pressure and oil life. The listing also says it covers other vehicle health items without naming them.

A cabin temperature setting lets the owner choose how warm or cool the car should be before getting in. The setting is made from the phone, so the car can be ready on arrival.

For electric GMC models, the app shows charging status and can point the owner to charging stations.

Trip planning, roadside help and service booking

Trip planning uses in-app maps, and the app can navigate a planned route. The listing says map features vary by location, so the detail available depends on where the owner is driving.

Roadside Assistance can be requested from inside the app. Service scheduling and dealership lookup are also listed, so an owner can book maintenance without calling first.
