text: can i use my wife's car navigation to track her where abouts....she drives  an acura tl?   i'm going to forego the assumption that everyone else has made regarding the status of your marriage and simply answer your question.  the short answer is no, there isn't currently a way to track your wife through your acura tl navigation system.  however, several cellular phone companies offer gps and for $9.99/mo. you can locate a cell phone user through services such as "family locator" through sprint,  "xora", "etrace" and other applications through nextel; and i'm sure other carriers are offering something similar.  as an aside, vehicles equipped with obdiii (on-board diagnostics 3) have gps tracking systems integrated into your cars ecm which will allow government agencies to track your location, speed, and even get updated data about the condition of your car (last time you had it serviced, for example).  with this technology they will be able to issue you a speeding ticket without even seeing you, or shut-down your car remotely if you don't pay your overdue parking tickets, etc.  the latest chevy corvette already has it.  check it out for yourself...
