Discover the OnStar app and its benefits for drivers
May 22 2026,
OnStar is the connected system built into GM vehicles (Chevrolet, GMC, Buick, and Cadillac). It allows your vehicle to be linked to your smartphone and gives access to a full range of features such as remote control, assistance, safety, and connected services.
These technologies are now at the core of the modern driving experience across Quebec, especially in Granby, Saint-Jean-sur-Richelieu, Brossard, and throughout the South Shore of Montreal.
GM vehicles also use the MyChevrolet, MyGMC, MyBuick, and MyCadillac apps to manage these features remotely.
At Granby Chevrolet Buick GMC Cadillac, we explain these technologies during vehicle delivery so every customer fully understands their vehicle. This is what sets us apart from other dealerships in the region.
