The three-button OnStar interface (above) allows a driver to get directions, information or help through a cellular telephone embedded in his car and connected to the system's communications centers.
Two photos accompanying an article on the OnStar communications system in the July 24 edition of Plugged In showed the in-vehicle navigation system interface for the 2000 Cadillac DeVille. The photographs did not show the OnStar interface. The Sun regrets the error.
