Where GPS trackers are typically hidden in vehicles

GPS trackers are small enough to fit in a matchbox, which means they can be placed almost anywhere on or under your car. The most common locations are the wheel wells (especially the rear wheels, where they're harder to spot), the undercarriage near the bumpers, inside the front grille, taped to the frame behind the license plate, or tucked into the OBD-II port under the dashboard on the driver's side. Some trackers are magnetic and stick directly to metal parts; others are wired into the vehicle's electrical system.

Less obvious hiding spots include inside the bumper itself, attached to the fuel tank, wedged in the door jamb, or placed inside a wheel tire. Trackers can also be hidden inside aftermarket accessories like dash cams, phone chargers, or seat covers if someone had access to your vehicle for an extended period. The goal is usually to place them where they won't be disturbed by normal driving or car washes.

Key Takeaways

  • Check the OBD-II port under your steering wheel first—it's the easiest place to hide a tracker and the quickest to inspect.
  • Inspect the undercarriage, wheel wells, and bumper areas with a flashlight and mirror, looking for unfamiliar magnetic devices or wired boxes.
  • A radio frequency (RF) detector can scan for active trackers, though it requires some technical knowledge to use correctly.
  • If you find a device you don't recognize, photograph it without touching it and contact local law enforcement before removing it.

Start with the OBD-II port under your dashboard

The OBD-II port is a small rectangular connector located beneath the steering wheel, usually within arm's reach. It's designed for mechanics to plug in diagnostic tools, but it's also the easiest place to hide a tracker because it's out of sight and doesn't require any installation skills. Turn off your engine, get down and look under the dashboard on the driver's side, and see if anything is plugged into that port besides your own devices.

If something is plugged in that you don't recognize, take a photo of it before touching anything. The device may have a brand name, model number, or identifying marks. Don't remove it yet—if you suspect someone placed it without your permission, law enforcement may want to document it first.

Inspect the undercarriage and wheel wells with a flashlight

Get a flashlight and a small mirror (a makeup mirror works fine). Lie down or crouch beside each wheel and look up into the wheel well, checking for anything that looks out of place—a small box, a magnetic device, or wires running along the frame. Pay special attention to the rear wheels, where trackers are often placed because they're less visible when you're driving.

Move along the undercarriage toward the front and rear bumpers, using the mirror to see surfaces you can't reach directly. Look for anything taped, bolted, or magnetically attached that wasn't part of the original vehicle. Trackers are often black or gray and roughly the size of a deck of cards, though some are much smaller. Take photos of anything suspicious before you touch it.

Check behind the license plates and inside the bumper

Remove your front and rear license plates (usually held by four bolts or screws) and inspect the area behind them. Trackers are sometimes taped directly to the bumper or frame in this spot because it's straightforward to access and relatively hidden from casual observation. Look for any wires, adhesive residue, or small devices.

If you see something, photograph it and note whether it appears to be wired into the vehicle's electrical system or if it's straightforward taped or magnetically attached. Wired devices are more complex to remove and may require a mechanic, while magnetic or taped devices can usually be photographed and documented without professional help.

Use an RF detector to scan for active trackers

A radio frequency (RF) detector is a handheld device that picks up signals from active GPS trackers and other wireless transmitters. You can purchase one online or at an electronics store for $50 to $200. Turn it on, set it to scan mode, and slowly move it around your vehicle—under the dashboard, around the wheel wells, along the undercarriage, and inside the cabin.

An RF detector will beep or light up when it detects a signal. Keep in mind that it may also pick up signals from your own devices (phone, key fob, tire pressure sensors) or nearby cell towers, so you'll need to distinguish between those and an unfamiliar tracker. If you find a signal in an unusual location, use the flashlight and mirror method to visually confirm what's there before assuming it's a tracker.

What to do if you find a device you don't recognize

Do not remove the device when ready. Instead, photograph it clearly, including any visible serial numbers, brand names, or model information. Note the exact location and whether it appears to be wired or straightforward attached with adhesive or magnets. If you believe someone placed it without your permission, contact your local police department and file a report. Provide them with the photos and the location of the device.

Law enforcement may want to document the device before you remove it, especially if you suspect the tracker is related to stalking, harassment, or theft. Once you have police documentation, you can remove the device yourself if it's straightforward taped or magnetically attached. If it's wired into your vehicle's electrical system, take your car to a mechanic and show them the photos so they can safely disconnect it.

Inspect aftermarket accessories and recent additions

Think about any new accessories installed on your vehicle in the past few months—dash cams, phone chargers, seat covers, floor mats, or upgraded speakers. Trackers can be hidden inside these items. Inspect any aftermarket device carefully, looking for loose components, extra wires, or anything that seems out of place. If you're suspicious of a specific accessory, remove it and examine it closely or have a mechanic inspect it.

Also check inside your vehicle for any unfamiliar devices plugged into the 12-volt power outlet or USB ports. A tracker could be disguised as a phone charger or air freshener. If you find something you don't recognize, photograph it and follow the same steps as you would for any other suspicious device.

Frequently Asked Questions

Can I remove a tracker myself if I find one?

If it's magnetically attached or taped, yes—straightforward pull it off. If it's wired into your vehicle's electrical system, take it to a mechanic rather than cutting wires yourself, as you could damage your car's systems. If you suspect the tracker was placed without your permission, contact police first and let them decide whether to document it before removal.

What if I find a tracker but don't know who put it there?

File a police report with the photos and location information. Law enforcement can investigate and may be able to trace the device to its owner through the manufacturer or service provider. Do not confront anyone you suspect—let police handle it.

Will a GPS tracker drain my car battery?

Most modern GPS trackers draw very little power, so they won't noticeably drain your battery. However, a wired tracker that's improperly installed could cause electrical issues. If you notice unusual battery drain or electrical problems, have a mechanic inspect your vehicle.

Can I use my phone to detect a GPS tracker?

Your phone cannot detect GPS signals or radio frequencies the way an RF detector can. Some apps claim to find trackers, but they are not reliable. An actual RF detector is the most effective tool for locating active wireless trackers.

What if I find nothing but still suspect I'm being tracked?

Trackers can also be installed through your vehicle's built-in systems (some newer cars have connected services) or through your phone if someone has access to it. If you have concerns about being tracked, contact local law enforcement and describe your suspicions. They can advise you on next steps based on your specific situation.
