Review on Enhanced GM/OPEL VXDIAG VCX Nano GDS2 and Tech2Win Diagnostic Tool with Global Diagnostic Programming System GDS & GDS2 by Joe Griffin

buyers beware! GM sells you this tool to interact with your vehicle, a program to use this tool ($249.00 for the privilege of installing it even though it should be included in the package) and a license to use the software. Security (additional fee). $55 for three days)! Even if you get a cracked version of the software, you cannot download the license and test your software. In fact, the device I received had scratches, which indicated to me that it was an item that someone had returned. Tech support won't even speak to you if you're not a mechanic. At this rate the manufacturer seems to have deliberately made it impossible for the car owner to repair their car themselves, so I'm sure this review from their point of view is just confirmation that the product is working as intended. Unfortunately I have to return the money and take the damn thing to the mechanic.
