General Motors Co. plans to offer subscriptions for its Onstar Guardian security services to anyone in the United States or Canada who wants to download a smartphone app, expanding beyond owners of GM vehicles in a step to generate recurring revenue.
Onstar Guardian services, including roadside assistance and crash response dispatching, will be offered through an Apple or Android smartphone app to people who don’t drive GM vehicles for $15 a month after a one-month trial, GM said.
