IFR GNS 430 with expired database

flying non-GPS approaches with the 430 should be fine since you're not
really using the database.

What about using it for locating missed approach holding points (a-la
NDB or DME substitution)? Since the database is out of date, you
can't use it for approaches, even non-GPS.

It depends on the HP - often it's a return to the OM using a
backcourse, or a nearby VOR, or intersection of 2 VOR radials. None
of these requires the database. Even an NDB would work if you have
ADF on board

From the Garmin manual: ( I have similar verbiage in my AFM
supplement. Yours could conceivably differ.)

"You may file your flightplan as /G if your GNS430 is a certified A1
(approach approved) or A2 (enroute and terminal only) installation. If
you are flying enroute, you may file /G with an expired database only
after you have verified all route waypoints. Non-precision approaches
may not be flown with an expired database. See your approved Airplane
Flight Manual for more information."

So to comment on an earlier point, you can still file /G, even with
an expired database, under the restrictions pointed out earlier. Note
you can file /G with a C129(A2) installation for which approaches are
never approved!

It's hard to imagine anyone thinking an expired GPS database would
prevent you from using the *other* navigational equipment in your
airplane - like an ADF or the independent VOR/ILS in the 430.
