Teltonika FMC650 — Professional 4G LTE Cat 1 Tracker with L1+L5 GNSS and Tachograph

The Teltonika FMC650 is Teltonika's most advanced professional GPS tracker — the direct successor to the hugely popular FMC640, raising the bar significantly across every dimension that matters for professional fleet management. Built to meet the highest requirements in vehicle telematics when many types of external equipment and accessories need to be connected simultaneously, the FMC650 is the natural choice for international and domestic logistics, refrigerated and heavy duty transport, agriculture, construction, mining, utility and emergency services.

Its most significant upgrade over the FMC640 is dual-channel L1+L5 GNSS — a separate dedicated GNSS module supporting both L1 and L5 frequency bands simultaneously for positioning accuracy approaching RTK-grade equipment. This makes the FMC650 the most accurate tracker in Teltonika's range and opens new possibilities for free flow electronic tolling system integration and precision fleet management. A new more powerful processor, increased internal memory, switchable CAN terminators for multi-node CAN networks, Iridium satellite connectivity for remote area coverage and full support for Teltonika's DualCam and DSM video solutions complete a device that is in a class of its own.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the FMC650 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Frequently Asked Questions

What is L1+L5 dual-channel GNSS and why does it matter?

Standard GPS trackers use the L1 frequency band only. The FMC650 uses both L1 and L5 simultaneously via a separate dedicated GNSS module — providing significantly improved positioning accuracy, particularly in challenging urban environments and for precision applications like free flow electronic tolling. The track quality approaches RTK-grade GNSS equipment.

What is the difference between the FMC650 and the FMC640?

The FMC650 is the direct successor to the FMC640 and supports all the same features. Key upgrades are dual-channel L1+L5 GNSS, an updated 4G modem with more frequency bands, a more powerful processor, increased memory, switchable CAN terminators and Iridium satellite support. For new deployments the FMC650 is the recommended choice.

Does the FMC650 download tachograph files remotely?

Yes — the K-Line interface enables remote digital tachograph DDD file downloading and live tachograph data via Teltonika WEB Tacho, supporting driver hours compliance monitoring without drivers needing to visit a download station.

Is the FMC650 compatible with the Tracking Hardware UK 1-Wire driver identification keypad?
