Where trackers are usually hidden, how to check the wiring and OBD port, when a detector helps and what to do if you find one.
To find a GPS tracker on your car, start with the places where trackers usually go: the OBD diagnostic port under the steering wheel, behind the dashboard and under the seats, and on the outside, the bumpers, wheel arches and frame. Then check the wiring for non-factory connections and, if needed, sweep the car with an RF detector. If you find nothing but still have doubts, see an auto electrician.
First, think about whose tracker it might be
A tracker in a car does not always mean someone is spying. Often it is there legally and the owner has simply forgotten:
- Car on credit or leasethe bank or leasing company fits a tracker as a contract condition.
- Comprehensive insurancesome insurers require a tracker or telematics device.
- Company carthe employer monitors the fleet and must inform the driver in writing.
- Used carthe previous owner may have left a tracker that stopped working long ago.
Check your contracts before removing anything. Taking out a leasing company’s tracker may breach the agreement.
Where to look for a GPS tracker on a car
Inside the cabin
- OBD port under the steering wheel. Check this first. A plug-in tracker in the diagnostic socket takes a minute to fit and a minute to remove.
- Cigarette lighter and USB. Some models look like an ordinary charger. If something is plugged in that you never bought, take a closer look.
- Behind the dashboard and under the steering column. Hardwired trackers are often hidden behind trim where power and the ignition switch are close.
- Under the seats and floor mats. Slide the seats fully forward and back, lift the mats and inspect the mounts.
- Glovebox and boot. Check the space behind the glovebox, the spare wheel well and the side panels in the boot.
Outside and under the bonnet
- Bumpers, wheel arches, frame. This is where magnetic, battery-powered standalone GPS beacons are attached. Shine a torch under the front and rear bumpers and feel inside the cavities.
- Under the bonnet. Near the battery, behind the headlights, in the engine bay recesses. Do it with the engine off, as parts can be hot.
Types of trackers and how to detect each one
| Device type | Usual location | How to detect it |
|---|---|---|
| Hardwired tracker | Behind the dashboard, under the steering column, under the bonnet | Non-factory wires, splices, an extra fuse |
| OBD tracker | Diagnostic port | Visible as soon as you look under the steering wheel |
| Cigarette lighter tracker | Lighter socket | Looks like a phone charger |
| Standalone beacon | Bumpers, boot, behind trim, on a magnet | Only a thorough inspection: it rarely transmits |
| Bluetooth tag | Anywhere with little space | Your smartphone warns about an unknown tag nearby |
How to check the wiring
A hardwired tracker runs off the vehicle’s electrical system, so the wires give it away. Look for:
- wires of a different colour or gauge from the factory loom;
- splices, electrical tape or heat shrink where there should be none;
- extra wires on the battery terminals or a spare fuse in the fuse box;
- a small box with an antenna or LED taped to a wiring harness.
Take photos before you remove any trim. It makes reassembly easier and gives you something to show a specialist or the police.
Will an RF detector help
An RF detector picks up the moments when a tracker sends data over the mobile network. The catch is that it does not transmit all the time. A hardwired tracker is usually active while the car is moving, and a standalone beacon may only check in once or a few times a day.
To improve your odds, start the engine or drive a few kilometres, then slowly sweep the detector around suspicious spots. Switch off your own phone or leave it away from the car, as it also transmits and confuses the readings. Sounds or heat are unreliable signs: working trackers are silent.
What to do if you find a tracker
- Do not break it: it may be evidence.
- Photograph the device and where it was fitted.
- Check your contracts with the bank, leasing company or insurer.
- If nobody claims the tracker, file a report with the police.
Fitting a tracker to someone else’s car and tracking people without their consent is illegal in Ukraine (Articles 163, 182 and 359 of the Criminal Code). Trackers may only be fitted to your own vehicles, and to company vehicles only after informing the driver in writing.
When to call in a specialist
If your own inspection found nothing but your car seems to “know” more than it should, go to an auto electrician or a diagnostics workshop. They will remove the trim, check the wiring harnesses and sweep the car with professional equipment.
If the device you found is a Teltonika or Bitrek unit and you want to identify the model, contact our technical support. For your own car you can fit a tracker of your own: a plug-in GPS tracker for the lighter socket needs no installation and takes minutes.
FAQ
Can a tracker work without being wired to the car?
Yes, standalone beacons run on their own battery and need no wiring at all. They connect on a schedule, so the battery lasts a long time. That also makes them hard to catch with a detector: look for them by inspecting under the bumpers, in the boot, behind trim and anywhere a magnet can stick.
Can my phone detect a hidden GPS tracker?
Your smartphone can only warn you about someone else’s Bluetooth tag travelling with you: recent iOS and Android versions have this feature. A tracker with a SIM card is invisible to your phone because it uses the mobile network. To find one you need a thorough inspection of the car or an RF detector.
Is it legal to put a tracker on someone else’s car?
No, fitting a tracker to another person’s car without the owner’s consent and tracking someone this way is illegal in Ukraine. It may fall under Article 182 of the Criminal Code. You can track your own car, and on a company vehicle the employer must inform the driver in writing about the tracker and its purpose.
Where can I get help if I cannot find it myself?
Go to an auto electrician or a workshop that installs car alarms and trackers. They will remove the trim, check the wiring and use professional detection equipment. If you suspect you are being tracked, document the facts and report it to the police first, so the search does not destroy possible evidence.
