Set your location in Bangkok and simulate a route out-bound using a major arterial road [freeway/expressway] and you should see something. Press the top LH corner [turn arrow] to scroll thru the route, when it finds a JC view it will display on the RH side of the screen instead of the route map.

The *.jcv file needs to be in a sub-folder named JCV in the Garmin folder of microSD card.
