Understanding GPS Trackers

GPS trackers come in various shapes and sizes, designed to monitor and report the precise location of a vehicle. They can be broadly categorized into two types: active (real-time) and passive (data loggers).

Active GPS trackers transmit data in real-time using cellular networks. This allows the person tracking the vehicle to access location information remotely over the internet. These trackers are often used by fleet and taxi companies for vehicle monitoring and theft recovery.

Passive GPS trackers, on the other hand, store location data in internal memory. This data can only be accessed in person, making it less convenient but still effective for tracking purposes. To learn more about the different types of GPS trackers, check out our GPS Tracker page.

Common Signs of a Hidden GPS Tracker

Detecting a hidden GPS tracker can be challenging, but there are several telltale signs to watch out for:

  1. Unusual Sounds: If you hear buzzing, chirping, or beeping sounds, it could be a tracker transmitting data.
  2. Loose Wires: Look for any loose wires connected to a battery-powered tracker hidden under the hood or in the glove compartment.
  3. Magnets or Metal Objects: Check for any magnets or metal objects stuck to the outside of your car, particularly under the vehicle.
  4. Battery Drain: A sudden drop in your car’s battery life could indicate a tracker using the battery.
  5. Alerts from Your Phone: If you receive an alert from your iPhone about an unknown Apple AirTag tracker nearby, it’s a significant sign. Android users can use the AirGuard app to detect Apple AirTags.

Tools Needed for Detection

To thoroughly inspect your vehicle for hidden GPS trackers, you’ll need some basic tools:

  • Flashlight: Essential for illuminating dark areas.
  • Mechanic’s Mirror: Helps you see into hard-to-reach places.
  • Creeper or Mat: Allows you to slide under the vehicle comfortably.
  • Electronic Sweeper/Bug Detector: Detects electromagnetic signals from active trackers. These can be purchased from the same places you find GPS trackers.

Performing an Exterior Inspection

Start by inspecting the exterior of your vehicle, focusing on common hiding spots for GPS trackers.

Step 1: Check the Wheel Wells

Use a flashlight and mechanic’s mirror to look inside both the front and rear wheel wells. Feel around with your hand in places you can’t see. If the hard plastic wheel well liner is loose, peel it back to check for any magnetized trackers attached to the frame or body.

Step 2: Inspect Under the Vehicle

Using a creeper or mat, slide under the vehicle to perform a thorough inspection. Focus on areas where someone could easily hide a tracker without taking too much time or effort. Keep in mind that the tracker could be covered in road dirt and grime.

Step 3: Examine the Bumpers

Trackers can also be hidden under or inside bumpers. Use a flashlight and mirror to perform a thorough inspection. In some cases, you’ll need to reach up and inside the bumper to feel around. While trackers can be hidden inside the engine compartment, it isn’t common.

Performing an Interior Inspection

Since hidden GPS trackers can be small, they can be tucked away anywhere inside a car or truck. Focus on places where such a device could be hidden quickly.

Step 1: Check the Data Port

Most GPS trackers are small and can be plugged directly into the vehicle’s data connector, usually found under the dash near the driver’s legs. If you notice something plugged into the data port, that’s a reason for concern.

Step 2: Inspect Hidden Areas

Use your flashlight and mirror to check under the seats, under and behind the dash, inside and behind the glove compartment, and in the center console. Trackers can also be hidden in seat pockets, between seats, behind sun visors, and elsewhere. Be aware that small modules like the one that runs the power door locks may easily be confused for something more nefarious.

Step 3: Examine the Trunk

Trackers can be hidden in the trunk, especially if you have a spare tire. Remove and inspect the spare tire, and peel back the trunk liner to check for any hidden devices.

Using Electronic Sweepers and Bug Detectors

Electronic sweepers, also known as bug detectors, are handheld devices that detect electromagnetic signals from radio transmitters and cellphones. These devices can help find well-hidden active trackers.

Step 1: Power Up the Sweeper

Turn on the bug sweeper and slowly walk around your vehicle. Depending on the sensitivity, you may need to hold it near all the locations mentioned in the previous sections.

Step 2: Detecting Signals

When the bug detector locates a suspect signal, it typically lights up, vibrates, or buzzes. This indicates that you should go over that area with a fine-toothed comb.

Step 3: Moving Vehicle Detection

Some trackers transmit only when the vehicle is moving. If you don’t detect anything at first, ask someone else to operate the vehicle while you keep an eye on the sweeper.

When to Seek Professional Help

If you suspect that someone hid a tracker on your car but can’t find it, a professional may be able to help. Technicians specializing in automotive electronics, car audio, and car alarms often have the necessary expertise and equipment.

Professional Inspection

A professional can perform a more thorough inspection using specialized tools and knowledge. They can also safely remove any hardwired trackers without damaging your vehicle. If you’re unsure about a component you’ve found, a professional will be able to identify if it’s actually a tracker.

Preventive Measures to Avoid Future Tracking

Regular Inspections

Perform regular inspections of your vehicle, especially if you suspect someone might be tracking you. This can help you catch any new tracking devices early on.

Use a Bug Detector

Keep a bug detector handy and use it periodically to check for any new tracking devices. This is especially important if you’ve found a tracker in the past.

Secure Your Vehicle

Ensure that your vehicle is always locked and parked in a secure location. This can deter potential trackers from planting a device. Consider investing in additional security measures like an alarm system or steering wheel lock.

What to Do If You Find a Tracker

Step 1: Remove the Tracker

Most hidden GPS trackers are battery-powered and held on by magnets or tape. If you find one, simply pull it loose. For trackers plugged into the car diagnostic tool connector or the cigarette lighter socket, unplug them.

Step 2: Seek Professional Assistance

In rarer cases where a GPS tracker is hardwired into power and ground, seek professional assistance. Cutting the wires may do the trick, but it’s essential to ensure the component you’re cutting out is actually a tracker.

Step 3: Report the Incident

If you find a tracker, consider reporting the incident to the authorities, especially if you suspect malicious intent. They can investigate further and take appropriate action. Document the tracker with photos and note when and where you found it.


Finding a hidden GPS tracker on your vehicle can be a daunting task, but with the right tools and knowledge, it’s entirely possible. Regular inspections and the use of electronic sweepers can help you stay one step ahead of potential trackers. If you ever find a tracker, remove it safely and consider seeking professional help to ensure your vehicle remains secure.
