No, the application won't work for the purpose you need. For example, Digital Photo Navigator is used to add and embed GPS tracking data on a map for the pictures you've taken. Then you can use that map to see where those pictures have been taken. It's not an image editor or transfer software to download the pictures from the camcorder.
As far as I know, the software for the JVC devices is not available for public downloading. The software is located on the CD-Rom that arrived with your device when you've purchased it.
There is a manual describing how to install the application to transfer the content, but it also specified that its location is on a CD-ROM.
