You have the large JCV file which should work fine in your 1200, the feature is enabled and the file path is correct for the unit. You can also put it in a JCV folder in the microSD's Garmin folder. However, nowhere all major junctions/exits have a JCV associated with them. You will have to find them on a route.
Try a simulated route from or to any major city using a major arterial multi-lane motorway, scroll thru the route and when you see the words 'Junction View' light up at the base of the screen, press then and you'll see the junction view.
