CNX-80 vs Garmin 430/530

thats one radio for that amount, not two.

The SL-30 is better than two radios.

Adding the CNX-80 would give you two
com's.

More like three (or four?).

I know the SL30 does alot, but its still allot for one radio.

Have you used one? It is a lot for a single radio. It's not a lot
for one that very effectively replaces two. Yes, it does cost more
to get the more capable unit than to get one with far less
functionality. That's not an aviation first.

I was debating the same question a month ago, I just got my plane out of
the shop last week, went with the garmin 430, garmin 327 x-ponder, ps
engineering 7000b audio panel and AM/FM/CD player.

I couldnt find enough information on the cnx80 to make an informed
decision, the 430 is a well tested GPS and does everything I need for it to
do, I had one in my old cherokee 180 and liked it so went with what I was
familiar with. The mx20 is something I plan on getting in about 6 months,
if you have the MX20, then you dont need a really expensive GPS/COM, the
mx20 will do everything and more of that the 430 or the cnx80 will do. I
have seen the MX20 used, awsome display.

It looks like the new CNX-80 is the way of the future. Has anyone used
one?

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.

It is pressure altitude and the 5 times per second GPS engine that give the
CNX it's advantages.

Tarver,

Hmm. Have you found the update rate of the Garmins lacking? In what kind of
situation?

The VNAV function for GPS will require the faster engine and pressure
altitude. If the operator is not using the VNAV function, then there is not
much difference; for now. If at some point the system is able to automate
ATC and free flight goes forward, more capability under CFR 14 is likely to
require the new generation of GPS equipments.

Besides that, both machines are Garmins.

My GNS430s have pressure altitude. By early next year I can upgrade
them to the raster refresh rate required by VNAV.

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

I heard the update was like $1000, but it may be 1500$, its one of those.
Personally I dont think I will use the vnav, thats why I got the 430, with
exception of vnav and entering in flight plans via the airways they are
esentially the same box.

I was out doing practice approaches today with my 430, its coupled to my HSI
and that is coupled to my auto pilot. even the DME arc was simple. flew a
perfect arc, well the auto pilot flew a perfect arc
