By 2007, more than two million General Motor vehicles in the U.S. and Canada may be equipped with the OnStar Turn-by-Turn Navigation system.
According to GM, the new service from OnStar will be standard for the first year on GM retail vehicles sold in 2007 including nearly all Buicks and Cadillacs.
The automaker also said that the system will be offered on other GM vehicles through a $100 optional OnStar package upgrade during the initial year of service.
After the first year, customers can renew their package for $299 a year, GM said.
