New Product Announcement: GPS 175/GNX 375 IFR Navigators (3/25/19)

Any idea when/if Garmin will release a Nav/Com/ ADSB box.

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
 
interconnect question

I'm a little confused on the G5/175 interconnects.

First off here's the install manual:
https://drive.google.com/open?id=1FJX4uCIcgluwN1uar0WLKRd2-fqEVAvm

Not sure why the manual has to be obtained from the dealer and is not posted on Garmin's site, but am posting it here so anyone can follow along.

On page 11-16 it shows a G5 ADI solely connected via RS-232.

On page 11-17 it shows a G5 HSI connected via the GAD-29B ARINC-429 pins and RS-232.

I'm wondering if its necessary to connect the 175 via RS-232 as I was planning on using the RS-232 on the ADI G5 for encoder output to a Stratus ESG and the RS-232 on the HSI G5 to connect to the Val Nav 2000 which is SL-30 compatible.

Just to be clear what is the purpose of the RS-232 connection if the 175 is connected to the GAD-29B via ARINC-429?
 
ARINC 429

Bob,

From what I know about the connection of a IFR GPS receiver to a EFIS system, you need to use the ARINC 429 box when you need autopilot steering commands.

ARINC Label 121 is the Horizontal Command (to Autopilot), needed for autopilot steering. If you don't have a autopilot, just need serial data for say, altitude encoder function, VOR/LOC/GS, you can just hook up the RS232.

Also, the SL30 just needs a RS232 connection as the RS232 is where signal for the left/right/up/down needle movement comes from.

I hope that answers you question.

Brian

Hello Bob,

You should be able to do something close to what you are describing.

Please contact us by email and we will provide some details and a wiring example.

Thanks,
Steve
 
there is no requirement for ADS-B in Canada and probably won't be for a decade

:)

Not quite...

In a Jan. 11 webinar, Nav Canada announced its proposed 1090 MHz extended squitter (1090ES) ADS-B Out performance requirements. Phase 1, which would be implemented Jan. 1, 2021, would include all airspace over 18,000 feet. Phase 2, beginning Jan. 1, 2022, would add Class B airspace which, in Canada, extends from 12,500 feet msl up to but not including 18,000 feet msl. Phase 3 is less defined, expanding ADS-B as needed to ?specific controlled airspace, en route or at an airport, starting no sooner than 2023.?

I'd really like to find out too. That would solve a lot for me.
 
Where to find GNX 375 Installation manual ?

Hello Noel,

Yes, according to the 2 installation manuals, both of these 2" navigators (the GPS 155 and the GPS 175) use roughly the same vertical rack space.

Thanks,
Steve


Hi Steve, I went on Garmin's website but can't find the installation manual for the GNX 375? Can you tell where to find them?
 
Steve:

Im planning to make a new panel for my RV-6A, based almost entirely on Garmin G3X architecture. I already have 2 x G5s , a GMU11 magnetometer, and plan to install 2XGSA28 servos, 1x GMC507 control, 1X G3X display and adhars, and in the future some Garmin Compatible Radio (GTR200) and IFR Nav (GSP175).

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 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.

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

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.
 
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
 
Toobuilder, u godda send em an email with your tail number for the IM.

Received my 375 a couple of days ago, install will take place in a couple of months, weather still too nice here 👍🏻

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!
 
Watching with interest because if it works with the D100 this means I could potentially replace my 327, GDL 82 and GDL 39 with this one box and still retain the D100 CDI, and still have weather and charts on my 796. 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! :p)

I had some quiet time in front of a 375 at Oshkosh. Was able pair BT to the unit and verified foreflight was able upload and download flight plans to the device. Other data feeds (wx, traffic) appeared to be working. Far from an exhaustive test, but seemed to work exactly like my GTN750 w/ FS510 and other GTN's with flight stream adapters.

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:

Questions for g3xpert

I?ve got dual G430s (non-WAAS) on my panel feeding my GRT WS EFIS system. I?m thinking about upgrading one 430 to the 355 navigator.

1. Will the 355 comm/navigator fit into the same slot as my old 430 (dimension wise)?
2. What wiring changes are required for the upgrade?
3. I have the TruTrac 385 A/P installed. Will this A/P play well with the 355?
4. What other considerations should I take into account in making this decision (ie navigation database updates, etc)?
5. Will the 355 cross feed navigation routing to the remaining 430 via the cross-fill function?

Thanks for your response.
 
Flight Logs on a GNX-375?

Quick question for the G3Xpert team (or whoever may know): Does the 375/175 have the flight log capability that 396 and x96 units have (shown in the photo below). It?s a feature I?ve used to catch up my flight logs when I?ve been lazy about recording Hobbs times. I?ve scoured the pilot guide and pushed just about every button to find a ?flights? record, but have come up empty so far. Does it exist in these units? Thanks!!

Cheers,
Bob

Bob,

Neither the GNX 375 or GPS 175 record a flight log like the GPSMAP 396 series units do.

Our newer portable units like the Aera 660 do have this capability however.

Thanks,

ICAO flight plan filing re equipment?

Ok g3xperts, next question... sporting dual G5, a GNX375, and a GTR225A only... which Aircraft COM, NAV, and Approach Equipment Qualifiers do I need to enter in order to correctly complete and file an ICAO flight plan?

Thanks :)
 
Tankerpilot,

Like you, I've thought about upgrading my single 430 to a GNC355 because of maybe needing LPV capability and concern about future support. I finally decided not to upgrade.

Here's why:

I understand how to use my 430. In your case you would need to understand both a 430 and a 355. They are similar but different. You can download the simulator and see for yourself.

You can upgrade a 430 to WAAS and the only external change is the GPS antenna and perhaps the coax. That's simpler than the wiring changes needed to install a 355. The depth and width are about the same but the 355 is not as tall, so a spacer is needed or you may need to move everything in your avionics stack to fill the vertical space.

Garmin has stated they are continuing to support GNS navigators.

You have dual GRT EFIS as do I. A 355 has much better graphics than a 430, but I display maps, weather and traffic on my GRT where the display is much larger than my 430 or a 355.

I really don't fly much actual IFR and I fly a lot of trips to one destination. That destination does not have a LPV approach. My home field is grass with no approaches and the closest airport to me is an air carrier field with ILS, VOR and GPS approaches. So my 430 gives me the capability I need.

I can purchase inexpensive database updates for my 430 and they are not serial number dependent so I can share a subscription with another owner. I don't believe that is the case with a 355.

It is less expensive to upgrade a 430 than to purchase a 355 and the prices of 430's are dropping so hopes of selling it to make up the difference are dwindling.

Just my thoughts, I hope they are useful.

Should the GNX 175 send frequencies to the Garmin 225? It looks like it should according to the manuals, but the frequencies don't seem to do anything on the 175 when touched, and I don't see an option to "send".

175 configured for Aviation output 1 on serial 3, and 225 configured for aviation in.

Thanks.

Vic
 
Thanks Jim Butcher

Thanks Jim. I was beginning to think no one wanted to reply to my questions.

I?m now leaning towards keeping what I?ve got - at least right now. I?ve been talking to a local avionics shop that periodically does GPS upgrade installs and hopefully a used 430W may become available at a reasonable price from one of their customers. The swap out would be much easier and I could then sell my 430 non-WAAS to someone at a reasonable price. Anyway that?s my current thinking.
 
GNC 355 Inquiry

I?ve got dual G430s (non-WAAS) on my panel feeding my GRT WS EFIS system. I?m thinking about upgrading one 430 to the 355 navigator.

4. What other considerations should I take into account in making this decision (ie navigation database updates, etc)?
5. Will the 355 cross feed navigation routing to the remaining 430 via the cross-fill function?

Thanks for your response.

The most significant advantage of the GNC 355 over the GNS 430 is the ability to fly RNAV approaches to LPV minimums.

The GNC 355 is a bit smaller than the GNS 430. You would need to install a new rack and connector for the GNC 355. The chassis of the GNS 430 is 0.64 inches taller with a similar width, although the GNC 355 screen is 1 inch larger with significantly higher resolution and readability.

The installation manual for that autopilot provides guidance for GNS 430W's and GTN 650's, The interface would likely be very similar to these two, although we have not tested this combination of equipment ourselves. You would want to reach out to the manufacturer of the autopilot to be sure.

There will be wiring changes. Without knowing a whole lot about the aircraft or the EFIS in the aircraft, it is hard to give you much of an idea about what wiring changes would be needed. Existing ARINC 429 and RS232 lines can probably be re-purposed to be used with the GNC 355, but you would need to confirm all connections pin for pin upon installation.

At this time, the GNS 430 and GNC 355 do not cross-fill flight plan information.

Thanks,

Trutrak Sorcerer autopilot - Garmin G3X

I?m currently operating at Trutrak Sorcerer autopilot system with a Chelton system. I?m shopping to upgrade my panel with a G3X and G5 along with a Garmin GPS 175 on an RV10.

I?ve sent an email to G3xpert but wonder if anyone is using a Trutrak Sorcerer with a Garmin G3X season system? Wondering if there are limitations?

Currently flying a RV10.

GA35 Antenna Included?

Hello,

I'm finally to the point where I'm going to order a whole bunch of Garmin stuff. I'm in the process of receiving quotes from several vendors. Some vendors say that the GNX 375 comes with a GA35 antenna and others say it's an extra $350.

I checked the Garmin website and it doesn't say whether the antenna is included or not. The first page of this thread says the antenna IS included. I read through the entire 23 pages and I don't see where the initial statement of inclusion is modified or contradicted.

Can someone shed some light on this? For reference, the Garmin p/n I'm using to obtain quotes is 010-01823-01.

Is this something that's left to the discretion of the dealer?

Thanks in advance!

For what it's worth, this initial system is going in my Glasair 1RG. I figure I'll practice up on the first installation before I start on my RV-3! If nothing else, I can stand to be without the Glasair longer than I want to be without my RV-3! I'll end up putting virtually the same exact system in the RV when the time comes.

Hello Rod,

The first posting in this thread says "The GNX 375 has a list price of $7995 including GPS antenna, rack, and connector kit.", and this is correct, but it takes ordering 2 part numbers to add up to $7,995.

The 010-01823-01 part number includes "GNX375, Standard Kit w/rack, backplate, conn kit, config module," and has a list price of $7,643.

The GMA 35 antenna (013-00235-00) has a list price of $352.

$7,643 + $352 = $7,995

It is sold this way because a lot of customers are upgrading an older GPS WAAS navigator and already have a GMA 35/36 antenna, and can take advantage of the slightly lower pricing of the GNX 375 010-01823-01 pricing.

Fortunately, we are seeing street prices considering less than list prices. I love my G3X Touch with GNX 375 and am sure you will too!

Thanks very much for the explanation. I noticed a discrepancy between the various list prices, but hadn't done the math to understand what was going on.
