Factory telematics is only one path. A used car can be factory-clean and still carry a tracker from a dealer, lender, fleet operator, rental company, insurer, or prior owner.
Inspect high-probability locations:
- OBD-II port and any pass-through dongle behind or near it
- Under-dash wiring, fuse taps, knee panels, and steering-column trim
- Battery terminals and suspicious inline power leads
- Glovebox, center console, seat rails, spare-tire area, trunk side panels, and cargo trim
- Dealer-installed modules, unlabeled black boxes, relays, antennas, or non-factory zip-tied wiring
- Former rental, fleet, repossession, buy-here-pay-here, delivery, and work-truck histories
If you find a device, identify it before removal so you do not disable an alarm, remote-start unit, ignition interlock, or required finance hardware on a vehicle that is not fully yours. On a purchased vehicle, photograph the install, remove it cleanly, and check that no account or app remains paired to the car.
