Anybody with Nuvi 40 or 50 got the junction view working with the new map and junction view on the sd card? What other files do I need to be included on the sd card?

3. Check that you have the correct jcv file for your particular unit. I think it is D3191040A for 40/50 but not sure.
4. This is important. Not anywhere near all junctions are shown even on major highways/freeways/expressways. Minor roads have none. Simulate a long route along a major artery and you'll soon see if it's working.

If you're determined to put lower 49 only on the unit, just dl the MS version from Post #2 and use Mapsource to select the parts you want.

The setup file structure is the same as what you have described x:/Garmin/JCV/*.jcv. There is only one jcv file in that subfolder and one map file (2012.4) on the sd card. I have tried both the D3191040A.JCV and D3060050A.JCV files one at a time. I have taken the same sd card to the nuvi 1450. The same sd card can show junction view on the simulated route on nuvi 1450. When I used it on the nuvi 40 for the simulated route, it will show a blank screen when I clicked on the junction view button when it is lighted up.
