But things just got a bit harrier for Jack. DetectNu, a Holland-based company has come up with a GPS and GSM jammer that you simply plug into your car's cigarette lighter. It will block any planted GPS tracker in your vehicle from transmitting location data back to CTU (or Jack's phone).
It also shuts down GSM mobile phone devices. Hopefully, Jack has a triband mobile phone so he switch to CDMA or perish the thought - analog. But even if the bad guys jam Jack's GPS phone or GPS tracking devices, don't worry, Jack always gets his man (or woman) - even if does take him 24 hours to do it!
