Where to look for a GPS tracker on your vehicle
A GPS tracker is a small device that transmits your car's location. The most common places to find one are underneath the vehicle (attached with a magnet to the frame or wheel well), inside the OBD-II port (a diagnostic connector below the steering wheel), or hidden in the bumper, grille, or wheel well. Start by getting a flashlight and checking under the car near the wheels and along the frame — trackers are often magnetic and stick to metal surfaces.
Inside the car, locate the OBD-II port, which is usually on the left side of the steering column, below the dashboard. It looks like a rectangular connector about the size of a USB port. A tracker plugged into this port will stick out slightly. You may also find a device hidden in the bumper, behind the grille, or tucked into the wheel well — these spots are harder to spot because they blend with the car's parts.
If you suspect a tracker but cannot find it visually, you have two options: use a radio frequency (RF) detector, which picks up the signal a tracker sends, or take your car to a mechanic or car security specialist who has the tools to scan for hidden devices.
Key Takeaways
- GPS trackers are most often found magnetically attached under the car, plugged into the OBD-II diagnostic port, or hidden in bumpers and wheel wells.
- A visual inspection with a flashlight under the vehicle and inside the dashboard takes 10 to 15 minutes and catches most devices.
- An RF detector can find trackers that are harder to spot, though these devices range from $30 to several hundred dollars depending on sensitivity.
- A mechanic or car security specialist can perform a professional sweep if you cannot find a device yourself.
Checking underneath and around the vehicle
Park on level ground and use a flashlight to inspect the underside of your car. Look along the frame, under the bumpers (front and rear), and around the wheel wells. Trackers attached with magnets are usually rectangular boxes about the size of a deck of cards, though some are smaller. Run your hand along metal surfaces — if a magnetic tracker is present, you may feel it before you see it.
Pay special attention to the rear bumper and the area behind the wheels, as these spots are less visible from the road and are common hiding places. Check inside the wheel wells as well, where a device could be tucked against the frame or suspension. If you find something that does not belong, photograph it before touching it, and do not remove it until you understand why it is there.
Inspecting the OBD-II port and dashboard
The OBD-II port is a standard diagnostic connector that mechanics use to read your car's computer. It is located below the steering wheel on the left side of the dashboard in most vehicles. Look for a rectangular opening about 2 inches wide. If a tracker is plugged in, you will see a device protruding from the port.
A legitimate OBD-II device might be a scanner you own, a tool your mechanic left, or a device your insurance company installed (which you would have agreed to). If you find something you do not recognize, take a photo of it and research the brand or model number online. Some insurance companies use OBD-II trackers to monitor driving habits, but you should have signed paperwork about this.
Using an RF detector to find hidden trackers
A radio frequency (RF) detector picks up the signal that a GPS tracker sends when it communicates with satellites or a cellular network. These devices range from basic handheld models (around $30 to $100) to professional-grade equipment (several hundred dollars). A basic RF detector will beep or light up when it detects a signal, helping you narrow down where a hidden tracker is located.
To use an RF detector, turn it on and slowly sweep it around your car — under the vehicle, around the bumpers, inside the wheel wells, and near the dashboard. The detector will alert you when it picks up a signal. Keep in mind that RF detectors can also pick up signals from your car's own systems (like tire pressure sensors or keyless entry), so you may need to learn what your car's normal signals sound like.
RF detectors are most useful if you suspect a tracker but cannot find it visually. They are available online and at electronics retailers. If you are uncomfortable using one yourself, a car security specialist or mechanic can perform a professional sweep with more sensitive equipment.
When to ask a professional for help
If you have searched your car thoroughly and found nothing, or if you found something but are unsure what it is, a mechanic or car security specialist can help. They have access to professional-grade RF detection equipment and know where trackers are commonly hidden. A professional inspection typically takes 30 minutes to an hour and costs between $100 and $300, depending on your location and the shop.
Some car security companies also offer GPS sweep services specifically designed to detect hidden trackers. If you are concerned about your safety or privacy, this is a reasonable step to take. A professional can also advise you on what to do if a tracker is found.
Understanding why a tracker might be on your car
A GPS tracker on your car may be there for several reasons. If you financed or leased your vehicle, the lender or leasing company may have installed one to track the car's location in case of default or theft. If you have a car loan with a high interest rate or poor credit history, this is more common. You should have received paperwork about this when you signed the loan or lease agreement.
An insurance company may have installed a tracker if you agreed to usage-based insurance (sometimes called "pay-as-you-drive" insurance), which monitors your driving habits to calculate your premium. Again, you would have signed paperwork agreeing to this. A spouse, family member, or someone else with access to your car may have placed a tracker there, which raises safety and privacy concerns. If you believe this is the case, consider reaching out to a trusted person or contacting local law enforcement.
What to do if you find a tracker
Before you remove a tracker, understand why it is there. If it belongs to your lender, leasing company, or insurance company, removing it may violate your loan, lease, or insurance agreement. Check your paperwork or contact the company directly to ask about it. If the tracker is there without your knowledge or consent, you have the right to remove it.
If you believe a tracker was placed on your car without your permission and you feel unsafe, contact local law enforcement. They can help determine whether the device is being used for illegal tracking or harassment. Keep the device as evidence and do not disturb it until police have had a chance to examine it.
Frequently Asked Questions
Can I remove a tracker if I find one?
It depends on who placed it there. If your lender, leasing company, or insurance company installed it, removing it may violate your agreement. If you placed it there yourself or someone installed it without your permission, you can remove it. If you are unsure, contact the company that may own the device or speak with law enforcement.
How much does an RF detector cost?
Basic RF detectors range from $30 to $100 and are available online and at electronics stores. Professional-grade equipment costs several hundred dollars. If you do not want to buy one, a car security specialist or mechanic can perform a professional sweep for $100 to $300.
Will my car's own systems trigger an RF detector?
Yes. Your car's tire pressure sensors, keyless entry system, and other wireless components emit signals that an RF detector will pick up. Learning what your car's normal signals sound like takes practice. A professional with experience using RF detectors can distinguish between your car's systems and an external tracker more easily.
Is it illegal for someone to put a tracker on my car?
In most places, placing a tracking device on someone else's car without their knowledge or consent is illegal. Laws vary by state and country, but this can be considered harassment, stalking, or invasion of privacy. If you believe someone has placed a tracker on your car without permission, contact local law enforcement.
How often should I check my car for trackers?
If you have no reason to suspect a tracker, a visual inspection once or twice a year during routine maintenance is reasonable. If you have concerns about your safety or privacy, check more frequently or ask a professional to perform a sweep.
