the garmin 430/530 is suppose to have a terrain data base that is suppose to be out soon, it wont be as good as the MX20, but for a 500$ upgrade, it could be worth it.

Yeah.

I haven't flown behind an MX20, but the Garmin. Well. Its got 8 colors. Count 'em. You don't get terrain worth diddley with that. The MX20 will show you sectional-chart-style terrrain and instrument approach plates. And airport diagrams (with your location on them) so you can't get lost.

I have heard, however, that the MX20 is not as sunlight-readable as the Garmin display.

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?
