I bought a 3-day VIDA subscription. However, I lost some time trying to get the login to work, and then we had the US Thanksgiving holiday. So it was more like a 2 day subscription. I looked through the web site and VIDA several times.
There is some very good documentation accessible within VIDA. But nothing marked TNNxx-xx. Perhaps that TNN naming is used with documents that are published as stand-alone documents, and the same content has no TNN name when viewed in the context of a vehicle in VIDA.
