Tech2Win is a powerful diagnostic software designed for GM vehicles. This guide provides a step-by-step installation process for the 2022.05 VXDIAG GM GDS2 and Tech2Win software, enabling users to effectively diagnose and troubleshoot their vehicles.

• Hardware: A VXDIAG VCX NANO for GM interface is required to connect your computer to the vehicle’s OBD-II port.
