Nope. Look at a list of approaches for some airports and you will see both
"GPS Rwy 16" and "RNAV(GPS) Rwy 16." My area of interest was the minimums
box, since the ones I ran across when just guessing usually had only
circling approaches. Thought that the approach to Frederick, MD, that Phil
Boyer used in the AOPA video on WAAS would have something other than
circling, but I was wrong.

If I understand your negative sentence construction correctly, you are saying
that the RNAV IAPs at KFDK have only circling minimums? Not so.
