TROY – OnStar gets turn-by-turn navigation this year as the GM division tries to boost profits and take on in-car navigation systems. The technology will be unveiled this week at the Chicago auto show.

Right now, OnStar subscribers can ask OnStar operators to give them instructions over the network, and can record them in some vehicles through a voice note recorder. With the new system, OnStar advisors will send instructions through the network to the car, which then plays back the audible commands through the stereo system.

Some versions of the Buick Lucerne and Cadillac DTS/STS will be the first to offer the technology in the 2006 model year. GM expects one million cars to be capable of the system in the 2007 model year. OnStar hasn?t confirmed an annual price for the service.
