You can't detect a template like that I'm afraid. The template will expand as soon as it's called. You would need to place something inside your Template:Navbox subgroup and check for that instead.

You could put something like  at the beginning of the template. It won't show anything, but at least you can detect it.

Also, as you can see, you need to use  instead of   to compare something. The  takes only the first 37 characters, since we only want to compare the first few characters.
