VXDIAG Nano GM not Connect to Corvette C6 (Customer Solution)

Car model: GM Corvette C6


Device: VXDIAG VCX Nano GM with USB cable not Wifi



Won’t connect to the car

Can’t get the licensee to load


How to solve?

Problem with WI-Fi unit, is that the Nano needs to be connected to the car so the nano has power to begin with. Also, OBDII port needs to be powered up, so on a C5, car has to be in run postion before the OBDII has power itself.

Because of that, even on the Wifi unit I have, I still use it with a cable so the laptop powers up the nano to begin with, and don't have to worry about the OBDII power instead..


When you load it make sure you run the installed updates from tech2win.

You also cant use a 64bit OS system it has to to be a 32bit device. The newer units (if bought on amazon) are 32bit and cant run from a Vm image that is 32bit OS.

I had the same issue. I pulled out a old laptop and installed win10 32bit and ran the updated add-ons from tech2win.


Load VX manager first, plug in the Nano, and get it working in VX manager. Hence click on firmware icon to update the firmware, then click on licence icon to install the licenses.

Now with the VX manager open and the nano plugged in, now load that auto install.exe of Tech2win to load it from the White disc that came with the Nano to your machine. Hence the autoinstall.exe will need to over ride some VX manager files when it installs, so VX manager has to be open with the Nano connected/being seen in VX manager when you load tech2 win auto install from the disc. Installing tech2 win, with VX manager not open and the nano not plugged into the machine will end up with install problems every time with Win 64bit system.

Lastly, if you are loading in the Newer VX manager, you have to go in and install the needed programs from inside VX manager (no long load into VX manger from the white disc). So Tech2, GDS2 and SPS have to be installed from within VX manager. If you check in VX manager and these are loaded already, uninstall and reload them from VX manager again if you are having problems. When you have done these three reloads, go back in the licence tab in VX manager and make sure you are showing licences for all three of these. If not, then go back to the main page and click on the licence ion to update the licences on the refreshed installed. I bring this up, since if you are using the last right hand top tab in VX manager to download the latest VX manager, you will have to install Tech2win/gds2/SPS from within VX manager (will still use the white disc to install Tech2win to the laptop to get the the desk top icon.

Now the glitch with A/C Delco TBS.
If you are using the older VX manager and older firmware on the Nano, when you get the screen to install the Bosch Tech2win driver and GDS2 in TBS (will be a pop up screen), you want to skip these installs each time you use TBS.

If you are using the latest VX manager and latest Nano firmware, then you want to install these two Bosch drivers from TBS instead.

Trust is, for TBS now, you want to be using the latest VX manager and firmware. When you load the two Bosch drivers, it going to to load another program that is needed to get the Nano to work (TBS changed about a year ago, and its this third driver that loads with the Bosch drivers that is needed to get the Nano to work with the system.
