CNS-80 is already WAAS equipped. It will cost more money to add it to
the GNS-430.
CNX-80 has airways in the database, GNS-430 does not.

I have an experimental airplane which now has a GX50 GPS and two comms, one
nav. The second comm is having problems, so intend to replace it and the
GX50 with either a CNX80 or a GNS430. Any comments on advantages of one over
the other??
In particular, which unit has the best comm/ILS qualities, which has better
GPS user friendliness, etc?
I have played with both the Garmin simulators for these units and like some
features on one and some features on another. I have read the previous
thread on the CNX80, but didn't get anything decisive from the comments.
Thanks for any info
