Paul,

I can't see that WAAS is not here to stay. But the 430/530 will support
WAAS, too.

Some dislike the operating of the CNX-80 and find it more convoluted
than the 430/530. Some love the CNX-80 for the ability to enter airways
in flightplans.

You might want to read the articles Aviation Consumer published on
this.

One problem I would see with the GX 55 that it is for sure an orphaned
unit since AFAIK GarminAT has announced it will be discontinued.

First of all I want to thank everyone's input. I read the article about
the comparison betweek the various boxes. Certainly the 430 and 530
remain very popular. If they will also support WAAS I assume that means
VNAV/LNAV capable also? Does anyone know when this upgrade for the
430/530 will be? Also how much???

Thanks, Paul
