I bought a vxdiag vcx nano for gm from www.vxdiagshop.com several weeks ago.
Once the software was received, I installed everything and figured out how to use it. First, the Tech2Win must operate as a virtual machine on your computer, so it doesn’t matter if you have a 64bit OS (as I do). There are no instructions for this, so this is how I completed the install:
– Install the VM software
– Install the VX software (the VX software is for the diagnostic connector that connects to the car, and takes the place of GM’s MDI)
– Use the Tech2 Win auto-install
– Install the GM MDI Manager
– Before you open Tech2 Win, you must first open and run the VX Manger software and connect the vehicle connector to the USB, so the VX manager recognizes it (if you do not do this FIRST, the Tech2 program will not be able to locate the interface, and will display “no communication”.
– Open Tech2 Win application directly, it will automatically open via through a virtual machine on your computer passively, there is nothing you need to do with the VM software.
– Once the Tech2 splash screen appears, press enter. You will be prompted to select which MDI the Tech2 software is supposed to recognize (this is why you must run the VX manager first, otherwise there will be no MDI selection present to select).
– Connect to the vehicle and begin polling data
I believe many of the respondents who state this did not work simply couldn’t figure out the necessary path. You must install everything, not just parts. The Tech2 looks for the VM software to open, so if you don’t install the VM hardware (thinking it’s not necessary), it may not function. Also, the VX OBD2 interface and VX manager software must be installed and running before you open the Tech2 application, otherwise the Tech2 won’t see an MDI interface (the VX spoofs an MDI serial) for communication.
Once I figured out the necessary path for operation, I am able to use this just as a GM supplied Tech2. You are still limited to model years 1992 – 2013 just as with a Tech2, so don’t think you’re going to use it on a 2014 – 2018 vehicle as they are not supported by the Tech2win anyhow.
I’ve been able to get into my 1996 K1500, 2004 CTS-V, 2005 Uplander (programmed the key fobs), and 2013 Cruze with ease. This is the Tech2 software, so you can execute anything a Tech2 can (save for programming a PCM, you need a separate service for that).
All in all, it’s a great price for the capabilities you get without the need for a separate hand held device. I used the same laptop which I use all of my performance tuning. I would be hesitant to use this product on a device with personal information, but that’s just me.
