How to choose a GM Tech 2 alternative on GM corvette

Have GM corvette, 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 eBay. 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. Only problem they outright say they CANNOT guarantee they can fix the locked status of my radio and i’d still have to pay. As an IT/Network technician, i couldn’t imagine telling people i can’t guarantee I can fix your network or pc problems, but you still owe me full price plus tax.

Enter the VXDIAG VCX Nano for GM scanner. 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 $119, 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. Cool thing is that the tech2win software runs just fine on my Windows 10 64bit laptop. Would be even cooler with a surface pro or similar tablet. 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.

The way to make the connection between the VCX Nano and the computer:

You plug the device into the OBD2 port, and then you either use Wifi back to the laptop to connect that way ($119), or you can use a usb cable instead ($109).

You have options: USB version & Wifi version
