GM's OnStar System Hacked

Posted by michael on from the think-outside-the-box dept.

Makarand writes "According to this Mercury News article users of GM's OnStar system are finding that they can modify their OnStar unit to make it work with commercially available mapping software after disconnecting it from the OnStar network. Websites and message boards are rife with step-by-step instructions to personalize OnStar's navigational and communications components. When a driver requests directions from OnStar his GPS data is routed over an analog cellular network to OnStar computers and the directions are read back to the driver on the same network. The price for this service is around $400 each year. Those who tap into their OnStar systems pay no such fees."

    Err , given that you have to phone up onstar to find your location , hence use a phone anyway , what exactly is the issue here? YOu stop the car to read your had held GPS and pay nothing , or you stop the car to phone onstar and pay $$$$$$.

    Have you ever used Onstar before? At least with my Grand Prix you just push the blue button, it cuts out the radio and you have hands-free communication with the person. It's kind of neat, but I've never used it so I didn't renew it when my free 1 year was up. The only advantage I saw was that if you're in an accident and the airbags deploy they'll call you to make sure emergency services gets to you. I didn't think it was worth $17 for this safety package though since I have a cell phone already. I never used it for directions since I'm a man... we never ask for directions!!! Now, if I could use my otherwise useless onstar system built into my car with a laptop then I find it interesting.
