My KLN 94 has a POH supplement that states the Pilots Guide is

required to have a current navigation database in order to use the KLN
94 for a non-precision approach."


OK there's no argument on that point. The difference we are having is a
terminal/enroute box that you don't shoot approaches with, such as the
GX55 in my plane. It can legally substitute for ADF/DME but some folks
are saying that the database is required to be current. My box is one
that says the user must verify waypoints if the database is expired.
