identify intersections - obviously the GPS does that itself and the
430
does have one nav radio built-in.

Paul,

I replaced my #1 radio/nav (a KX170B) with a 430 about a year ago and
keeping the #2 KX170B. I continue to use the com of the #2 and
consider it a "necessary". The nav of the #2 is now used for backup
and I do not feel it is necessary. I have a Garmin 195 on the yoke and
I could use it as emergency backup if the 430 went TU. Save the $2k or
not -- it's your call but I agree you can get along fine without the
second nav.
