You're running refrigerated trucks, construction gear, or a mixed fleet and your current tracker can't keep up with the data you actually need. The FMC650 is the step-up from the FMC640 — same feature set, but with a faster processor, more internal memory, and external GNSS and LTE antennas for cleaner signal in tight bays or rural dead zones. It pulls FMS CAN data (J1939), fuel consumption (J1708), and live tachograph data (K-Line) so you're not guessing at your numbers. Switchable CAN terminators let it sit on a multi-node network without dropping off. Dual-SIM or eSIM keeps you connected across carriers. USB-powered for the initial config, so you're not wrestling with a live vehicle
