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.

From the way I am reading it, it sounds like the restriction is only for
certain types of GPS-specific procedures, such as RNAV-STARs, RNAV-SIDs, and
Q-Routes and T-Routes. I'm not sure what a Q-Route or a T-Route is, but I
have heard of RNAV-STARs and RNAV-SIDs. I've never used them up to now, and
it doesn't worry me much that I won't be able to use them with my current
GPS.

Normal routes (even off-airway, which is specifically mentioned) and normal
STARs, SIDs, and other procedures, even GPS approaches, don't seem to be
covered in this AC.

I'm no lawyer, nor even an expert, but that's how I read it...

Did AOPA get wind of a specific paragraph that is more broad than this?

A T-Route is a low altitude RNAV route. I believe they can be numbered
from 200-500 (e.g T200).

A Q-Route is a high altitude RNAV route.

So far as the restriction people have been stating having to do with not
being able to use the uncertified GPS units as a substitute for ADF/DME,
that stems from the AIM (1-2-3) (and possibly a change that has not been
published) restricting this type of usage to units that are compliant with
AC90-100.
