GPS Worries

Submitted by:
Mr. Luna, I don't know why any of your readers are worried about their car gps systems giving information away. GPS is a one-way service, meaning that the GPS unit only receives data from the satelites. It can then lookup location based on maps stored on internal memory. It does not transit any sort of data to determine location. OnStar, however, is a different story. It can transmit location information. You can always lookup how to remove the OnStar antenna on the web, and should be fine after that is disconnected. You do lose all of the OnStar features if you do this.

JJ Luna Responds:

Good point, Sam, you may be right. (But could Osama bin Laden use a GPS without fear of an incoming rocket?)
