Linda Marshall, Chief of GM’s OnStar Unit Steps Down image

Linda Marshall, president of GM Co’s OnStar unit, is leaving to pursue after opportunities, after little more than a year on the job.

Her place will be taken by Terry Inch, OnStar’s director of sales, marketing and business planning, who will fill the position on an interim basis.

“We would like to thank Linda for her vision, leadership and contributions to the evolution of the OnStar brand and platform,” said a statement from OnStar.

“Under her leadership, OnStar restructured the organization and implemented important long-term initiatives to further grow the business in the future and strengthen its foundation,” GM said.

Marshall joined the company in November 2010 as executive director of OnStar’s global business strategy and development, replacing Chris Preuss as OnStar’s president, who left after 13 years with GM to start his own communications consulting firm.

In 2011 OnStar had to face criticism over privacy concerns when the unit planned to keep a data connection with customer vehicles after service was canceled, unless a customer asked for it to be shut off, but the company later reversed the course. OnStar, which provides safety, security, communication and convenience services in vehicles, has more than 6 million subscribers in the U.S., Canada and China.
