AvWeb has an article in todays issue saying that only the GPS 400/500

Admittedly I didn't read the entire circular (I have a Garmin GNS430), but my
quick skim of it seemed to indicate that the non-compliant models are no
longer allowed to use GPS in lieu of ADF or DME, where that is applicable,
unless alternate instructions are provided by ATC. This would imply that for
home-grown RNAV approaches these units would still be legal. Did I interpret
incorrectly?
