I tried connecting to Chrysler, via the J box, i conected fine to 2013 Grand cherokee and i logged in OK to Witech. When i try to download the TIPM file from Witech, i get this message from them "error connecting to the web server. Press continue to try again."

Witech says it is not there problem to help, since i am using Autel's J box which is not supported by them.

Any ideas on how to solve the problem?

To top it all, i was trying to enable a rear view camera option on the Gateway; it turns out that you need to login into Dealer-Connect (which impossible unless you are a dealer) in order to update the TIPM file, then via witech you can reflash it; which requires the download i was  not able to do. Thank you for your feedback.
