AvWeb has an article in todays issue saying that only the GPS 400/500
series and G1000 are the only IFR certified navigators that are legal to
use.


Does anyone know the rationale for why the GPS receivers can not longer
be used as ADF or DME subs? Or is there any rationale stated by the FAA?



It does not affect those operations. Read the AC carefully.
