Recently PSA Group have added the Tech2win subscription as standard included in the GDS2 Subscription. I think this is great news. I recently installed this remotely for a customer using Teamviewer and took some screengrabs along the way. This works with Passthru tools such as drewtech Mongoose GM, Drewtech cardaq, Cardaq m, Bosch KTS and even Ford VCM3. However it does not work with Autel Passthru :( you will need to make sure the relevantd drivers are installed.
Purchase the length of subscription required, in my case the customer already had a GDS2 license so didnt need to worry about ordering again.
Like with your GDS2 Installation java installation is critical so please check install now. JAVA WEBSITE
