I just added a GNX375 and love it. I have access to another plane in need of upgrade and there’s minimal panel real estate and it needs com as well. Anyways thanks Garmin the GNX375 is awesome
Hello NewbRVator,

Glad to hear you like your GNX 375!

As you know the GNX 375 (10.85") and GNC 355 (11.23") are larger (longer) than the GPS 175 (6.58"), so adding additional functionality isn't without some penalty.

There is also the practicality of using a 2" vertical display to view/control more than 2 devices.

While we can't comment on products which may or may not be in development, it is safe to say that these dual-device units are probably optimum for the 2" series.

In case of an electrical failure, I plan to use my G5 connected to other air source pitot and static, (back up battery) for an emergency flight instrument.

My question is related to a possible catastrophic failure of the CAN Bus (suppose a short or ground on one of the Can signals). In this case, Is the G5 still going to work? or the CAN bus short circuit will damage my G5 and could not be using it as a backup flight instrument ?

Moreover, is there any recommendation on the CAN Bus order of "bus hanging" for my G5 ? (for example should it be the last on the chain near the termination resistor ?).

Thanks !

Maximo Lema.

Hello Maximo,

The G5 will continue to operate just fine as an independent backup primary flight instrument should there be a CAN bus short or other failure.

A G5 may be placed anywhere on the CAN bus. No one place is better than another.

Thanks,
Steve

Thanks Steve:
That is a very good news to know for my planned new system.

As per CAN bus specs if one side (CAN H or CAN L) failed (shorted to GND or cut) entire CAN bus should switch to protected single-wire mode.

Question

Hi Steve,

Just got a new GNX 375 yesterday and have 2 simple questions:

Is there a dedicated backplate on the tray like legacy products? If so, I'm not seeing it. Included in the box (looking like it was thrown in as an afterthought) was a small backplate that has no relation to the connector config on the box. This one is PN 011-043430-00.

Which leads me to question 2:. Went to the Garmin site to download the installation manual (to figure out the backplate situation), and I can't find it. Where can I get this manual so that I can install my expensive new box?

Thanks

Hello Michael,

Yes, there is a backplate that holds the 2 coax connectors and the 2 D-sub connectors. It is shown in the exploded diagram for the mounting rack assembly in the GNX 375 installation manual.

A Garmin dealer selling these products direct to EAB installers will provide the necessary materials and guidance, including the installation manual, needed by the installer.

Please contact us directly should you have any trouble receiving this information from your dealer.

Sorry that you had a rocky start, but you are going to love the GNX 375!

Thanks,
Steve

Who has the installation manual for the GNX375? Just received mine today and there is only a pilots guide included. I cannot find anywhere online the install manual. Any help would be greatly appreciated!

I have the HS74 control panel and assume that my trutrak Gemini AP would also interface with the 375.
Obviously need to get smarter on this.

Figs,

Finally had enough down time to complete the GNX375 install for phase I of my upgrade (ADS-B compliance plus a great navigator, tied to my legacy Dynon network). Thanks to Brian (pdtofly) for the help wiring the 375 backshell and deciphering the interconnects to the D100 and GMA340!

The good news is that the RS-232 out to the D100 works, and GPS data appears on the D100 and D10A, the encoder data from the D100 works with the 375, and the AP (controlled via my AP-74) flew HDG, TRK and NAV just as hoped. Brian wired-up a connector with the 429 connections for future use with the phase II EFIS upgrade, but without an HS-34, I can't use that capability during this phase, which is OK. You may be able to get the vertical mode capability with your HS-34. Here's a couple pics, one on the ground, and one in the air, during the ADS-B validation flight...which was completed at 2332Z on 12/31/19 (I didn't want to be too early! )

That's great news too Greg! Can you verify that you mean the 375 BT'd to your iPad, and you saw Flt Plan (magenta line), traffic and wx on the iPad? Good stuff! I haven't been up again since the test hop to test more capabilities, as I'm giving a little (long overdue) TLC to various fairings:



But I am looking everywhere for the funds for phase II, and the upgrade to a 21st century EFIS . Not sure if my new project is the place to look...but I'm checking all the nooks and crannies!



Cheers,
Bob
