Once again: it works with the NGX perfectly. AFAIK NGX is using the same Navdata as the T7, so why should it be a nav data issue?
/edit: I clearly understand what you mean, that Navigraph (btw, AS NAVData Pro uses just entry and exit point as well) should provide all waypoints on the transition. But I can hardly imagine that its impossible in the real airplane to manually select a terminal waypoint.
