GPS Tracker 4G OBD FMC003 — Real OEM data with no wiring

Plug it into the OBD2 port and start reading real odometer, real fuel and engine alerts in seconds.

The FMC003 is Teltonika's 4G GPS tracker with OBD2 connection that reads both standard OBD-II parameters and the manufacturer's proprietary OEM data. That sets it apart from generic OBD trackers: it does not estimate fuel, it reads it directly from the vehicle's system. It does not calculate odometer by GPS, it takes it from the manufacturer's CAN.

Up to 32 OBD parameters available depending on the vehicle model: fuel level, odometer, coolant temperature, RPM, battery voltage, fault codes (DTC) and more. No wiring installation, no electrician needed: it connects directly to the OBD2 port that every car and van has had since 2003.

Ideal for renting fleets, logistics companies and managers that need reliable vehicle data without dealing with a complex installation. Bluetooth 4.0 included for driver identification with iButton or reading of external sensors.

The 170mAh backup battery raises an alert if someone unplugs the device, which also makes it a discreet and effective anti-theft option.
