I'm at a bit of a loss. I have 2015.30 installed with the JCV file D3060160A. When i open that file I can see that there are thousands of juntion pictures in the file. I was able to see where those juntions were. I started a simulation to these xact junctions but the junction view never comes on. If I manually select a junction I can see tha the "Lane Assist" button is greyed out. I also have a Europe map on my device and have no problems with junction view.
