I'm assuming something along the lines of the following:


* GMA 340 audio panel

* GMX 200/traffic MFD

* Dual SL30 nav/comms

* GPS 400 gps

* GTX 330 transponder

* MD 200 VOR/LOC/GS indicator

* GI 102 VOR/LOC indicator

* GDL 69 XM receiver

If I was starting from scratch, I think I'd go with a GNS-480 and an SL-30.

I figure by breaking out the nav/comm function from the gps function, I
can lose either and still shoot an approach.

The SL-30 alone is enough to get you vectors to an ILS.

I think my single point of failure might be audio panel

That's certainly a single point of COM failure, but it won't keep you
from navigating.

Of course, that's just one man's opinion, and what works for me may
not make sense for you.

We've got an MX-20 in one of our planes, and personally I don't get
much use out of it. The graphics update is way to slow for the moving
map. If they came out with a faster version, it might be more
attractive.
