Foxwell NT520 - What’s New?

Foxwell NT520 Pro – This is for those looking a decent car diagnostic tool for his/her own car(s), usually as personal use.


Why did I said NT520 (NT510) is good for personal diagnostic?


  1. NT520 is used for diyer only (not for repair-shops)

usually good for a customer with one or two cars, better with five or less

5 programs at most for a unit (for 5 car brands)


Note that you can get ONLY 5 car brands software authorization with NT510, while you could get ALL software authorization with NT520 and install less than 5 programs on the NT520.


Please  delete the software you’re not using if you want another program. For example, if you have MB, VAG, GM, BMW, Volvo installed on your NT520, but now you need Ford software, you should remove one of programs you’ve installed and then install the Ford. It’s because the SD card storage limit will lead to bad user experience like running speed and also it’s necessary to leave some space for data recording in in diagnostic tests.



  1. Software from Foxwell is cheaper than that from Autel or Launch

Foxwell software authorization: 60 euro per program (with FREE update lifetime)

Autel software update: free for the first two year for English version & free for the first year for other language version, then 1200 usd per year for all programs

Launch software update: free for the first two years, then 499 usd per year for all programs


  1. NT520 is a hand-held tool

It depends. Some like handheld, some like pad, some like phones)



IMPORTANT: foxwell nt510 vs nt520


  1. hardware improvement:

Foxwell NT520 adopts 9X35 + 128MDPR + SPI (2.8-inch screen), which help start faster and running faster than NT510. And it would have better compatibility for some cars


  1. more cars and software authorization:

Mercedes Benz, Acura, Alfa Romeo, Abarth, American / European Ford (Not incl. Au Ford), BMW, Mini, Chrysler, Fiat, GM, Honda, Hyundai, Kia, Holden, Land Rover, Jaguar, Lancia, Toyota, Lexus, Scion, Maserati, Opel, Vauxhall, Rolls-Royce, VW, Audi, Skoda, Seat, Porsche, Peugeot, Mazda, Ferrari, Aston Martin, Volvo


NT510 is authorized with 5 programs at most.

NT520 has no limit of software authorization, but 5 or less is better for a unit to install, for it can work well if with much software inside.


  1. more special functions:

TPMS, CVT, Injector, Odometer, Gear learn, Other  service maintenance function


  1. easier to update sw:

“Update” is added to the new NT520 Foxwell, so you can connect the device by a USB cable with a laptop/PC to update, download and install software for use. You don’t need a card reader any more like NT510 update.
