Q: ARE THERE ANY DETECTION DEVICES THAT WILL DETECT A GPS UNIT ON A VEHICLE?

A: YES. THE DD3000 AND DD3001 ARE BOTH GPS DETECTORS. ACTIVE GPS UNITS USE A SIM CARD TO SEND ITS LOCATION TO THE HOST. THIS SIGNAL IS THE SAME AS A CELL PHONE SIGNAL (GSM, CDMA, ETC.). THESE UNITS CAN DETECT WHEN THE GPS UNIT SENDS THESE TYPES OF SIGNALS. THESE UNITS CANNOT DETECT GPS LOGGERS. LOGGERS STORE THE LOCATION INSIDE THE UNIT AND DO NOT SENT THE SIGNAL OUT.
