Naw, a GPS approach is an RNAV approach but an RNAV approach is not a GPS approach.

If you have an actual RNAV unit, like say a KNS 80, then you can "move" a VOR and create waypoints you can fly to. So you can shoot an RNAV approach with a GPS because the database will already have these waypoints in it.

But you can't make do a GPS approach with an RNAV unit. While GPS IS aRea NAVigation (get it?), it's not actually an RNAV unit, which is a specific piece of equipment.
