Top VXDIAG VCX Nano Scanners Review 2018

Top VXDIAG VCX Nano Scanners: Review 2018 


Planning to buy a diagnostic scanner? The VXDIAG VCX Nano line of scanners offers some of the best options for diagnostic products. It’s safe to say each and every one of them is a top-quality tool for scanning a vehicle’s onboard systems.

A VXDIAG VCX Nano is basically a PC-to-vehicle interface. It plugs into a vehicle’s OBD2 port and then connects to a PC. The connection can either be wired (via USB cable) or wireless (via Wi-Fi).

Either way, once a connection is established the scanner will be able to run various diagnostic functions like reading DTCs, resetting systems, adaptations, programming, actuation etc.

Note that VXDIAG VCX Nanodevices rely on diagnostic applications to carry out their functions. For example, while the VXDIAG VCX Nano GDS2 and Tech2Win come with GDS2 and Tech2Win software, VXDIAG VCX Nano JLR SDD comes with SDD.

On this page, we review three of the best VXDIAG VCX Nano scanners. But first, you will get a summary in form of a comparison table followed by a comprehensive buying guide.


Best VXDIAG VCX NANO Products Review

1. VXDIAG VCX Nano GDS2 and Tech2Win Diagnostic Programming System for GM/Opel


Like all other VXDIAG VCX Nano boxes, this particular unit acts as an interface between your vehicle and PC. It doesn’t use Wi-Fi or any form of wireless connection and instead connects to a vehicle’s computer using a cable.Depending on the OBD2 interface of your vehicle, this scanner will offer functions like DTC error codes, relearn, advanced reset and so much more. It comes with a program that installs on a computer. From there you can use the GDS2 and Tech2Win applications.


So which vehicles does this VXDIAG VCX Nanotool support? That would be GM and Opel models.

It is fully compatible with all the current and most legacy protocols. They include

  • CAN
  • Class2
  • GM LAN
  • KW2000
  • UART
  • SAE-J2534-1
  • SAE-J2534-2

With regards to applications, first, it supports PC-based diagnostics that rely on Global Diagnostic System &nD-A-Sh; both GDS and GDS2. Additionally, it works with Tech2Win, a diagnostics platform for GM vehicles.

Note, however, that this VXDIAG VCX Nano will only work with Tech2Win when its software is installed on a 32-bit PC. That goes for Windows 7 as well as Windows 10.

As far as diagnostics, you can use it with third-party diagnostic applications that scan any system in a vehicle. Whether it diagnoses the engine, ABS,SRS, transmisson, instrument panels and what have you, it’s almost certain this device will work with it.


On one end the adapter features a port that hooks directly to the vehicle. The other end has a USB port. That’s what you use to connect the VXDIAG VCX Nano to a computer.

The connection will enable the vehicle and PC to communicate while using the adapter as an interface. You can use Windows XP or a later version. Note that in case you’re running Windows 7 or 10 the machine needs to be a 32-bit.

Functional features

By supporting vehicle protocols (CAN, Class2, GM LAN, KW2000, UART, etc.) and standards (SAE-J2534-1 and SAE-J2534-2 standards), this VXDIAG VCX Nano box makes it possible to do vehicle maintenance and generate service reports.

The GDS2 software specifically supports diagnostic functions. You can read and clear codes, freeze frame data, retrieve VIN and ECU information, manage output control functions, and retrieve the diagnostic history of a vehicle.

While the device also supports service programming system (SPS), you will need to purchase a software subscription for that.

On its part, Tech2Win offers almost all the features of GM’s Tech2. That includes PIDs, graphing, programming and reprogramming of modules.


A compact device, this VXDIAG VCX Nano is a pocket-size gadget. It measures 8.3 x 6.3 x 1.9 inches and weighs 9.6 ounces.

2. VXDIAG VCX Nano GDS2 and Tech2Win Diagnostic Programming System for GM/Opel Wifi Version


Save for connectivity, this Wi-Fi version of the VXDIAG VCX Nano is similar to the cable version. They are both interfaces that link a vehicle’s computer system with a PC. Plus they both enable diagnostic functions like DTC error codes, relearn, advanced reset etc.

The biggest difference is how they connect to a computer. While the cable version uses a cable (obviously), this one uses a wireless connection (Wi-Fi). But it does come with a USB cable just in case you prefer a cable connection.

Once connected to a computer you can use GDS2 and Tech2Win applications.


It is a GM/Opel adapter that connects to the OBD2 port. The device is compatible with all current and most legacy protocols like

  • CAN
  • Class2
  • GM LAN
  • KW2000
  • UART
  • SAE-J2534-1
  • SAE-J2534-2

Like the cable version, this adapter is compatible with the Global Diagnostic System (GDS2) as well as Tech2Win. In fact, you get both when you make the purchase.

Besides that, it also supports third-party applications that run diagnostic functions for all onboard systems. Which means if you have the device you can diagnose the engine, ABS, SRS, transmission, instrument panels and so much more.


Now, this is where the Wi-Fi version of VXDIAG VCX Nano boasts unique features. Instead of connecting to a PC using a USB cable, it does so wirelessly using Wi-Fi.

So how it works is that the OBD2 port of the adapter hooks to the OBD2 port of a vehicle. And instead of using a USB cable to link the adapter to a computer you simply use Wi-Fi. That will enable the computer to communicate with the vehicle’s computer systems.

As you might already suspect, the computer must be Wi-Fi enabled. But in the package is a USB cable for those who don’t fancy a wireless connection. Also noteworthy is that the VXDIAG VCX Nano installs in a Windows XP or Windows 7 (strictly 32-bit) computer.

Functional features

You can use the VXDIAG VCX Nano WiFi version for various diagnostic functions thanks to the GDS2 and Tech2Win applications.

Specifically, GDS2 makes it possible to carry out diagnostic functions. They include read and clear trouble codes, freeze frame data, retrieving VIN and ECU information, managing output control functions, and retrieving the diagnostic history of a vehicle. You can also purchase the subscription for service programming system (SPS).

On the other hand, Tech2Win is excellent for PIDs, graphing, programming and reprogramming of modules. It is ideal for road tests.

As already mentioned, the VXDIAG VCX Nano for Jaguar and Land Rover comes with a software that installs in a computer. The two then communicate via a USB connection.

But not just any computer will do. It should be a Windows machine running Windows 7 or a later version. Also, the OS should strictly be a 32-bit version. Minimum system requirements include 4GB RAM and i5 processor.

Functional features

Perhaps the most important functional feature of this scan tool is JLR’s Symptom Driven Diagnostics (SDD) that accompanies the device. The diagnostics system is one of the most efficient in fault finding.

It doesn't just retrieve codes it also analyzes them and tells you what exactly is faulty with the vehicle. Additionally, the diagnostic report will come with recommended fixes. That makes your work a lot easier.

Generally, the SDD system supports reading and clearing of codes for the engine, ABS, and SRS. You can also use it for programming & reprogramming modules, programming keys, clearing adaptations, DPF regeneration, activating pumps for brake bleeding etc.
