I believe with Option A or B you will also need an audio panel. The GNC 255 has a built in two place intercom.

GTN 650 GPS navigator with NAV/COM
GTX 345R Transponder/ADS-B In/Out
$11995 + $4995 = $16990

Option B:
GTN 650 GPS navigator with NAV/COM
GTX 45R Transponder/ADS-B In/Out
$11995 + $3895 = $15890

Option C:
GNX 375 GPS navigator with Transponder/ADS-B In/Out
GNC 255 NAV/COM radio
$7995 + $4495 = $12490

..besides slightly more panel space needed for option C?

The GTN 650 is taller (2.65"). Than the GNX 375 (2.02"). The GNC 255 is legacy height (1.65"). The GTX 345R can be remotely controlled by the GTN. The GTX 45R is a remote equivalent but can only be controlled by a G3X display, not a GTN, although it can display ADS-B in on a GTN.

Option A - one item on panel
Least panel space height

Option B - one item on panel
Same panel space as option a (least) - but requires G3X

Option C - two items on panel
Most panel space height and no remote LRU

Again, this has nothing to do with vertical approach guidance, which it does provide like all GTN and WAAS GNS units.

OK I am confused... As nyrikki stated the manual shows ARINC-429 connections in the connector pinout and in the INTERFASES section of the same manual it states:

"3.3.3.1.1 ARINC 429
The Interfaced Equipment ? ARINC 429 page allows the configuration of data formats and speeds of ARINC 429 inputs and outputs."


So, is ARINC-429 supported or is it a separate option? This will make a difference for many of us.

ARINC is built in.

With A and B, failure of a single box leaves you with no panel mounted navigation. With C it takes two failures.

I guess you're talking about legal IFR navigation, the G3X screens all have built in WAAS GPS's that work quite well as back up nav source.

Here you go.

The first is for the 175,



For those interested in the 375, it is a little deeper.



Good luck.

Brian

Question. Can one GNX375 drive a HSI and a CDI? Specifically two G5's or a G5 and a KI209?

Can a nav/com be hooked up to the same KI209 if the GNX375 is hooked to it as well.

It is my understanding that a G5 has only one input?

Thanks in advance.

Hello NewbRVator,

You can certainly drive 2 G5 displays with a GNX 375, but we may not understand your entire system. What is your NAV/COM?



Thanks,
Steve
