Plug-and-Play GPS Tracking for Light Vehicle Fleets

## Overview OBD GPS trackers connect to the standardised OBD-II diagnostic port found in virtually every car and light commercial vehicle manufactured after 2001. Installation requires no tools and no wiring knowledge — plug the device into the port (usually located under the dashboard on the driver's side), and the vehicle is live on the platform within minutes. Beyond GPS tracking, OBD-connected devices read real-time data from the vehicle's engine management system via the CAN bus: fuel level, odometer reading, RPM, engine fault codes, coolant temperature, and battery voltage. This gives fleet managers a complete picture of each vehicle's mechanical health without any additional hardware. ## Who OBD Trackers Are For OBD trackers are the fastest and most cost-effective path to fleet tracking for light vehicles. If your fleet consists primarily of cars, vans, or light commercial vehicles and you need to get vehicles tracked quickly without specialist installation, OBD is the right choice. They're particularly popular for: - **Company car fleets** where drivers may change vehicles frequently and self-install is a requirement - **Courier and delivery fleets** that need rapid deployment across dozens or hundreds of vehicles - **Mixed fleets** where OBD handles the light vehicle portion alongside hardwired units in heavier vehicles ## Limitations to Be Aware Of OBD trackers derive their power from the OBD port, which means they are active whenever the ignition is on and dormant when it's off (depending on the vehicle and port power configuration). They do not support digital output (relay control), so vehicle immobilization requires a hardwired device. If you need immobilization capability or advanced I/O, see our Hardwired GPS Trackers.
