OnStar

In September 2011 the president of OnStar stated that the service had more than six million customers. On May 9, 2018, Vauxhall Motors announced that Vauxhall OnStar, alongside Opel OnStar services, would cease to operate after December 31, 2020, following Groupe PSA's purchase of Vauxhall Motors and Opel from GM. A new aftermarket interior rear-view mirror with a built-in OnStar module, branded as OnStar FMV, became publicly available on July 24, 2011. It provides some of the features an OEM system has, such as Automatic Crash Response, Stolen Vehicle Tracking, Turn-by-Turn Navigation, and Roadside Assistance. The OnStar service relied on CDMA mobile phone voice and data communication, primarily via Verizon Wireless in the United States and Bell Mobility in Canada, as well as location information using GPS technology, a core component of automatic vehicle location. More recently, TELUS and Onstar announced a new arrangement in 2021 for 4G and 5G in-vehicle mobility services. Drivers and passengers can use its audio interface to contact OnStar representatives for emergency services, vehicle diagnostics and directions. The OnStar service allows users to contact OnStar call centers during an emergency.
