We have a Garmin 430 and an MX20 and they work really well together. The
terrain display on the MX20 is great, and the resolution on VFR and IFR
charts is sharp and the map's easily readable in direct sunlight. The MX20
is easy to use and configure, and really enhances the capabilities of the
430. I'd only go for a 530 if there wasn't enough space in the panel.
Never seen a CNX80 in action, but it sounds like an enhanced 430. Still,
UPSAT (and now, of course, Garmin) has been marketing the CNX80/MX20 combo.
Go figure, they want to sell 2 boxes instead of 1!!

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?
