296 seeing small airports in 50nm scale

I just pulled by Skymap IIIc out and relaced it with the Garmine 296.
There are certainly things I like better about the large screen IIIc
but I really like the crisp colors of the 296 and the fast update
rate. The turn coordinator seems really good and may work in a real
IMC emergency. In anycase, I just too it on a test flight from
Sacramento to Albuquerque (any excuse to fly right?). One thing I do
not like is that if I set the GPS to the 50nm scale (the one I like on
long trips) I only see large airports. I really like to know where all
the little airports are without having to query the GPS for nearest
(I'm in a single engine Mooney). I have tried but cannot find how to
configure the anticlutter algorithm to not drop airports. Has anyone
else tried this and gotten it to work?
