How to block GPS tracking

Updated February 21, 2017

A GPS tracker is a device used to track the location of a vehicle. There are two types of trackers available to the public: a logger tracking system and a real-time tracking system. A logger tracking system remembers all the locations a vehicle has been and stores them on a hard drive. The tracker then must be connected to a computer to retrieve the information. A real-time tracker sends signals to a GPS receiving system every 5 to 10 minutes. This will track a vehicle's real-time movements. If you believe you are being tracked, you can buy a product to block the signal.

  1. Shop around and find a GPS blocker. The blocker can cost anywhere from £32 to £650. It will stop most GPS tracking devices from sending signals to a GPS receiver. The more expensive ones will block signals up to hundreds of feet away, while the cheaper ones will block signals only up to a few meters.

  2. Plug the GPS blocker into your car's cigarette lighter. Plugging it in will activate the blocker, and you will essentially be invisible to any GPS monitoring systems.

  3. Deactivate your GPS blocker when you don't need to use it. Do this by simply unplugging it.

  4. Tip

    You don't have to buy a car GPS blocker. If you buy a handheld, portable blocker, you must manually activate it with the flip of a switch or the press of a button.


    It's illegal to block or tamper with any GPS tracking device that has been placed in a vehicle for law enforcement reasons. If you're not sure about a tracking device attached to your car, consult your local law enforcement. GPS blockers are illegal in some areas; check your local laws before buying and using one.
