Recently ran into an issue where i wanted to replace my aftermarket pioneer (didn't like it and much prefer my smart phone) with a stock unit. Found a cheap OEM unit on chinacardiags.com. After install, i realized that factory head units are tied to the original cars VIN. No problem, i'll pay the dealership to fix the issue.
Enter the VXDIAG VCX Nano. I was looking into clone tech II's for the past couple weeks and stumbled onto this gem. There is very little info on this product, but i still had more faith in this thing and myself more than my own dealership so i took the plunge. For $109 on http://www.chinacardiags.com/wholesale/xdiag-vcx-nano-for-gm-opel-gds2-diagnostic-tool-17409.html, I basically have the software version of a tech II device. I was able to unlock my radio in a matter of minutes. Have never used a real or upscale scan tool device so i can't compare but just poking through some of the menus, it looks like i can do anything a tech II can. I'm sure there are reasons for owning an actual tech II device over just software, but i wanted to try something different out of curiosity and explore other options for those that want an even cheaper alternative.
Putting tech2 win into win 7 compatibility mode is not hard to do.
Go to the start icon for tech2win, right click it and go to properties, and see if you can click the box and make it run it in win 7 mod.
If the box is grayed out and you can not do it this way, click on the windows icon, type in run in the search box, then find run program made for a previous version of windows in list it will bring out and click on that to open that program. From here, it pretty straight forward to find Tech2 win, and change tech2 win so it running in win 7 compatible mode.
As for SDS, need to see that if it has for any type of account already set up in it's memory. Hence in VM, gds2 should run fine, but without a active account in SDS, it never going to connect to GM to pull firmware files down that way instead.
Hell who knows, and if the SDS program on the disco does not have a hidden account on it, maybe you can access GM via the cloud software instead.
Huge update and to make the Nano work with win 10 64 you have to load the problems as follows.
1.Load the device
2. Execute MDI.exe
3. Install VXmanager
4. Execute auto install with VXmanager running.
