Thanks! I must have copied the wrong JCV file to the JCV folder (they are tied to the maps?). The intersection where I knew there was a junction view and it wasn't working (it just came up with a white screen when manually viewing it) was entering the Southern Expressway in Adelaide. I also tried the intersection you were referring to via simulation with the same result. After re-extracting the JCV file from the above link and placing it in the JCV folder (and deleting what was in there) it now works like it should (via simulation)! I think it didn't work because I might have had both JCV files in the folder (the large one plus the Nuvi 30/40/50 specific one).
