Look and Feel

Like its slimmed-down predecessor, the NT624 Elite, the expanded NT644 Elite has a tablet-like feel in a rugged shell. Its ample 4.3” screen makes navigating its exhaustive menu efficient while the simple button layout eliminates much of the guesswork. 

Between its simple configuration and ready-to-use updated software, it takes no time to start fixing trouble codes right out of the box. And while the rubber casing makes it feel relatively ergonomic in your hands, the lay-flat design makes it easy to use on a work surface while connecting it to your vehicle.


For all of its internal bells and whistles and expansive utility, the NT644 Elite’s connectivity to exterior components is surprisingly restricted. One glaring indicator of these limitations is the fact that it is only Windows compatible.

To be fair, Foxwell offers lifetime updates on its software, but for an industry that changes fast, this might be the least they could do. Unlike some pricier models, there is no bluetooth connectivity to your vehicle. There is no wifi for wireless updates. In fact, the only real connections are the standard adapter to your vehicle and a corded link to your PC.


Its front-to-back comprehensive functionality makes the NT644 Elite an impressively versatile OBDII scanner, able to handle jobs that normally take several tools to accomplish. It sports an impressive support system, working with the majority of international manufacturers in a variety of functions. Here is the breakdown of its versatility:

  • Over 60 supported vehicle makes.
  • 10 OBDII functions including O2 monitor test, I/M readiness and on-board monitor test.
  • 19 essential service reset functions.
  • Full system diagnosis for all ECMs (drive, chassis, body and electrical systems).

The range of reset functions gives users complete control in resolving common trouble codes. Within a few minutes, users can identify and fix issues in service areas including:

  • Oil Light Reset
  • EPB (Electronic Parking Brake)
  • ABS Bleeding
  • TPMS
  • Diesel Particulate Filter System
  • SAS (Steering Angle Sensor Calibration)
  • CVT
  • Battery Replacement

The NT644 Elite’s range of functions is impressive but the way in which it guides the user is where this scanner truly shines. From the main menu, the first option is its Auto VIN feature. This lets the scanner immediately locate the car’s vehicle information so that it can calibrate and operate accurately.

Once you access the vehicle information, you have the option to diagnose, which the NT644 Elite presents in a novice-friendly format. You can do a full-system Quick Scan or you can isolate a particular control module to inspect.

Live and post-scan freeze frame data are easy to access immediately and save for later use. You can check performance of individual components via three different graph types and text. Data can be stored to a micro SD for later use, or you can hook the scanner to a printer for hard copy records.


The NT644 Elite is powerful enough for the professionals and intuitive enough for the enthusiastic beginner. The scanner facilitates the repair process, automating information retrieval and data-sorting tasks to make work fast and easy to understand. It may not be as fast as some more expensive models, but its adaptability and time-saving, practical operation ensure its long-term value.
