DETROIT General Motors has tapped McCann Erickson's office in Birmingham, Mich., already a client roster shop, to promote the use of Sirius XM Radio to owners of new and certified used GM vehicles, the agency confirmed today.

Interpublic Group's McCann will tout Sirius XM subscriptions through the GM dealer network and across the marketing divisions for Chevrolet, Buick, Pontiac, GMC, Saturn, Hummer, Saab and Cadillac.
 
"We are thrilled to have been chosen to work with GM on this fast-growing technology and entertainment platform," said Garry Neel, CEO of McCann Detroit. "Our experience in working with the GM corporate brand and helping drive demand across all GM divisions should prove valuable as we support the many opportunities that lie ahead for GM with Sirius XM Radio."
 
Ad spending was not immediately available. The business moved to McCann following a review.

Campbell-Ewald in Southfield, Mich., also an IPG shop, was the incumbent. Ultimately, the competition came down to McCann and Boston-based Digitas, also a roster shop of GM, per sources.
