Can't give you directions though as I relied on my gps....and several prayers that I wouldn't hit a cow or other cattle while traveling there.
I can say though that initially my gps didn't have the place either but I didn't have a problem when I navigated to "Van wyk road" in general instead of the exact place. It's a pretty rural and small road so once you're on it you can just look for the massive church and you'll be there easily.
