FMB641 Tracker Benefits

FMB641 Tracker Benefits Description
Always Know Where Your Vehicles Are No more second guessing. See your vehicles on the map and stay in control throughout the day, whether they’re on a long run or making local drops.
Better Customer Updates
(Without Chasing Drivers)		 Give accurate ETAs and handle “where’s my delivery?” calls with confidence. You have the information to hand, even when the driver is busy.
Stronger Security and Theft Deterrent Tracking helps protect your vehicles and trailers by giving you fast visibility when something doesn’t look right, so you can act sooner and reduce risk. Combined with our geofencing, you'll be notified when your vehicle is moving when it shouldn't be.
Clear Accountability for Journeys and Stops Settle disputes quickly with a reliable record of where a vehicle went, when it arrived, and how long it was there. Helpful for customers, sites, and internal reviews.
Less Admin, Fewer Check In Calls When tracking is in place, you spend less time phoning drivers for updates and more time running the operation. It’s a simple change that saves time every week.
Confidence During Compliance Checks Having journey visibility alongside your transport data helps you spot issues earlier and keep better oversight of how vehicles are being used, without digging through paperwork.
One Place to Run Your Fleet Keep tracking, reporting, and fleet visibility together in TachoMagic. It’s easier for your team, quicker to train, and far less messy than juggling multiple systems.
Remote Downloads Ready When You Need Them If you decide to add remote tachograph downloads later, you’re already set up with a tracker designed for tachograph vehicles, so you can expand without starting again.

GPS Tracking Built for Commercial Vehicles

The main strength of the FMB641 tracker is its tracking capability. Once installed, it provides continuous visibility of your vehicles whenever the ignition is on.

With GPS tracking enabled, you can:

  • See where your vehicles are in real time
  • Monitor movement throughout the working day
  • Identify unauthorised vehicle use
  • Improve response times and route planning
  • Reduce uncertainty around vehicle location

All tracking data is securely sent to your tracking platform, allowing you to log in and view vehicle locations from anywhere.

Full Route History & Journey Replay

In addition to live tracking, the FMB641 records detailed journey history. This allows you to look back at where a vehicle has been, when it stopped, and how it moved throughout the day.

Journey replay features make it easy to visualise routes rather than relying on guesswork or driver recollection.

Geofencing & Location Alerts

When used with TachoMagic, the FMB641 supports geofencing. This allows you to define specific areas on a map and receive alerts when vehicles enter or leave those zones.

Geofencing is commonly used for:

  • Monitoring depot arrivals and departures
  • Keeping track of site visits
  • Improving security and theft prevention

With TachoMagic, these alerts can be sent via both SMS texts and emails.

Remote Tachograph Downloads

With the FMB641, you're not just getting a tracker - it can also automatically download your driver and vehicle data!

This means when the vehicles ignition is on, it will communicate with the vehicle's tachograph, automatically download driver card and vehicle unit data, and upload it to your tachograph analysis provider.

If you use TachoMagic, both your GPS and tachograph analysis is all accessible in one easy-to-understand platform.
