01 What Is the Teltonika FMB920?
The Teltonika FMB920 is a compact, hardwired GPS telematics terminal produced by Teltonika Telematics, a Lithuanian company and one of Europe's leading GPS device manufacturers. Founded in 1998, Teltonika supplies tracking devices to over 150 countries — and the FMB920 is their single best-selling product in the "Easy" (basic) tracker category.
At its core, the FMB920 is built around the Teltonika TM2500 module, which integrates a quad-band 2G GSM/GPRS modem, a 33-channel multi-constellation GNSS receiver, and Bluetooth 4.0 Low Energy connectivity. The device measures just 79 × 43 × 12 mm — thinner than a standard pen — and weighs only 54 grams.
Unlike wireless battery-powered trackers, the FMB920 is permanently wired into the vehicle's electrical system (6–30V DC), drawing power continuously. This means: unlimited operating time, always-on connectivity, real-time ignition detection, and the ability to remotely immobilize the engine via the digital output (DOUT) pin. An integrated 170mAh Li-Ion backup battery keeps the device online briefly if vehicle power is cut.

02 Key Features & Capabilities
Multi-Constellation GNSS
GPS + GLONASS + Galileo + BeiDou + SBAS + QZSS + DGPS + AGPS. 33-channel receiver with <2.5m CEP accuracy and -165 dBM tracking sensitivity — the highest precision available in this form factor.
Bluetooth 4.0 LE
Connect Teltonika EYE beacons, temperature/humidity sensors, BLE door sensors, headsets for driver calls, and OBDII dongles via Bluetooth — turning the FMB920 into a multi-sensor data hub.
Crash Detection
Built-in 3-axis accelerometer detects sudden impacts above configurable G-force thresholds. An automatic crash alert with GPS location fires instantly — critical for emergency response in accidents.
Remote Engine Immobilizer
Digital output (DOUT1) connects to a relay that cuts engine ignition. Send a single SMS or app command to remotely prevent the vehicle from starting — the most effective anti-theft measure available.
Green Driving Scenario
Monitors harsh acceleration, harsh braking, harsh cornering, and excessive idling in real time. Generates driver behavior scores — reducing fuel consumption by up to 15% in fleet deployments.
170mAh Backup Battery
Integrated Li-Ion backup keeps the device online for several minutes after vehicle power is cut — enough to send a power-cut alarm with GPS location before the battery drains, preventing silent tracker disabling.
128MB Internal Flash
Stores GPS records and events locally when cellular signal is unavailable. Data is transmitted to the platform automatically when network is restored — ensuring zero location data loss in weak-signal zones.
Bluetooth Config (No USB)
Configure the FMB920 wirelessly via Bluetooth from a smartphone using the Teltonika FMBT mobile app. No need to physically locate the tracker and connect a USB cable after installation.
FOTA — Over-the-Air Updates
Firmware updates are delivered remotely via FOTA Web without requiring any physical access to the installed device — critical for large fleets where manual updates would be impractical.
03 GNSS Accuracy & Multi-Constellation System
The FMB920's most technically impressive attribute is its positioning system. Rather than relying solely on the American GPS constellation, it receives signals simultaneously from four major satellite systems:
- GPS (USA — 31 active satellites) — the foundation of civilian tracking
- GLONASS (Russia — 24 active satellites) — improves coverage at high latitudes and in dense urban environments
- Galileo (EU — 30+ active satellites) — highest civilian positioning accuracy available
- BeiDou / BDS (China — 45+ active satellites) — excellent coverage across Asia, including Bangladesh
- SBAS, QZSS, DGPS, AGPS — augmentation systems that further improve accuracy and acquisition speed
The result is a position accuracy of <2.5m CEP (Circular Error Probable) — meaning 50% of all location readings are within 2.5 meters of the true position. Compare this to typical consumer GPS apps on smartphones, which achieve 3–8m accuracy. For insurance telematics, legal evidence capture, and precise route adherence, the FMB920's accuracy is exceptional.
04 Bluetooth 4.0 LE — Sensors, Beacons & Headsets
The FMB920's Bluetooth 4.0 Low Energy (LE) radio is arguably its most underappreciated feature. It transforms the tracker from a simple GPS device into a multi-sensor data hub that can monitor conditions far beyond location:
Teltonika EYE Beacon
Detect driver ID tags, temperature, movement, and magnetic field changes. Identify which driver is operating each vehicle in a fleet.
BLE Temperature Sensor
Monitor cargo or cabin temperature in real time. Critical for pharmaceutical, food, and cold-chain logistics across Bangladesh.
BLE Headset
Drivers can make and receive calls hands-free via the FMB920's Bluetooth headset support — improving road safety compliance.
OBDII Dongle
Connect wirelessly to the vehicle's OBD-II port to read engine RPM, fuel level, coolant temperature, fault codes, and odometer data.
Inateck Barcode Scanner
For logistics and delivery operations — scan delivery confirmation barcodes directly from the vehicle and log them with GPS location and timestamp.
FMBT Mobile App
Configure all FMB920 settings wirelessly via the FMBT app on Android — no need to locate the installed tracker or connect a USB cable.
05 Tracking Scenarios & Intelligent Alerts
The FMB920 runs firmware-level scenarios — intelligent rules that trigger specific actions or transmit data when defined conditions are met. These go far beyond simple location reporting:
- Green Driving: Monitor harsh acceleration, braking, cornering, and speeding — generates eco-driver score cards
- Crash Detection: Accelerometer threshold trigger sends instant alert with GPS coordinates to emergency contacts
- Jamming Detection: Detects GPS or GSM signal jamming attempts — fires alert even in no-signal conditions using backup battery
- Excessive Idling Detection: Alert when engine runs for longer than a configured time without movement — reduces fuel waste
- Towing Detection: Detects if the vehicle is being towed while ignition is off — immediate anti-theft alert
- Unplug Detection: Fires alert if device power is disconnected — prevents silent tracker disabling by thieves
- Auto Geofence: Automatically defines a geofence around the vehicle's last position when ignition turns off — alerts on any movement
- Manual Geofence: Draw custom zones on the map — enter/exit alerts for each zone
- DOUT Control Via Call: Trigger digital output (relay/immobilizer) via incoming phone call from an authorized number
- Trip Detection: Automatically records complete trips with start/end points, duration, distance, and speed profile
- GNSS Fuel Counter: Estimate fuel consumption based on distance traveled and vehicle fuel economy parameters
- Overspeed Detection: Configurable speed limit — alert fires when exceeded

Step-by-Step Installation Procedure
PLAN THE INSTALLATION LOCATION
Choose a hidden location inside the vehicle — behind the dashboard, under the seat, inside the center console. The internal GNSS antenna requires a reasonably unobstructed sky view through the vehicle roof or glass. Avoid mounting directly on metal floors where signal is shielded from above.
INSERT SIM CARD
Insert a standard SIM card with active GPRS data into the SIM slot before mounting. The SIM must support GPRS data and be active with a data plan (minimum 50MB/month). In Bangladesh: Grameenphone or Robi recommended for widest 2G GSM coverage. Ensure PIN lock is disabled.
CONNECT POWER WIRES (RED + BLACK)
Connect the Red wire to a permanent 12V/24V fused power source (use a 3-amp fuse inline). Connect Black to a solid chassis ground point. Test voltage at the harness connector before proceeding. The voltage range is 6–30V, covering all standard vehicle systems.
CONNECT IGNITION DETECTION (WHITE)
Connect the White wire (DIN1) to the vehicle's ignition/ACC wire — this wire goes live when the ignition key is turned to the ACC or ON position. The FMB920 uses this to detect engine on/off events for ignition alerts and trip logging. Verify using a multimeter before connecting.
CONNECT IMMOBILIZER RELAY (ORANGE — OPTIONAL)
For remote engine immobilization: wire the Orange (DOUT1) wire to the positive terminal of a relay coil. Connect the relay's normally-closed (NC) circuit in series with the vehicle's ignition circuit or fuel pump wire. When DOUT1 activates, it energizes the relay, interrupting the circuit and preventing the engine from starting.
CONFIGURE VIA FMBT APP OR CONFIGURATOR
Power on the device. Open the Teltonika FMBT app on Android and connect via Bluetooth. Enter your tracking server (APN, IP, port) settings. Set up geofences, sleep modes, speed alerts, and driving behavior thresholds. Alternatively, connect via USB on a Windows PC using the Teltonika Configurator software for advanced configuration.
VERIFY ON TRACKING PLATFORM
Log in to your tracking platform (TrackersBD, Wialon, Traccar, or MototechGPS). Confirm the device appears online, location is accurate, ignition status is correctly showing, and test the immobilizer relay by sending a DOUT command. Drive a short test route and verify trip recording.
