I've never flown an MX20 so I can't comment on that. But
I would say that if you don't need the display area of the
530 (which you don't if you have an MX20) then you could
save $5K or so and go with a 430. You get all the same features
for less $$$ and panel space. (Actually there's ONE useful
feature you don't get, which is the auto-identification and
auto-"DME" from VORs, which is a very nice feature but
not indispensible).

In an article at http://avionicswest.com/archive/shootout.htm#2003 about
Garmin 530 vs CNX-80, many of the pilots said that they would want a
combination of a Garmin 530 AND an MX20. I do not understand. Isn't
the Garmin 530 also an MFD capable of displaying multiple inputs, like
weather and terrain? Can someone tell me why both might be desirable?
Does anyone have experience with an MX20?
