For the G3X guys in regards to the new transponders just released.
Will they fit in the same slot as the 327?
Can you pipe out the weather and traffic into a 796 via Bluetooth or wire to replace the GDL39?
Is the depth of the 345 the same or less than the 327?
Hi John,
The behind panel depth for the GTX 327 is 8.77 in. to the back of the connector backshell.
This same depth is 10.09 in. for the GTX 345 (1.32 in. longer).
Just for reference, the GTX 330ES depth is 11.25 in. to the back of the connector, so the GTX 345 is 1.16 in. shorter than the GTX 330ES.
Thanks,
Steve
John,
I have dual G3x's, GTN650, and 327 transponder, in my RV8, what would your recommendation be for easiest, most cost effective, 2020 compliant, ADSB upgrade?

Garmin Experts,
These Transponders look great, I have a few questions:
1) Am I correct thinking that a GTX 345 (with integrated WAAS/GPS) could replace a GTX 330 ES, a GDL 39, and a GPS 20A?
2) When compatible with a G3X Touch (currently estimated Q3 2016,) could the GTX 345 be hardwired to both a PFD and a MFD or will one display need to be bluetooth connected the way a GDL 39 is now?
3) When your website reads, "Compatibility is extended to the G3X? Touch glass flight display and is expected in Q3 2016" does this refer to its full ADS-B IN functionality, i.e. replacing a GDL 39 or would the ADS-B OUT not work before then either? My question is: Could one buy a GTX 345 now to replace a GTX 330 ES to give a G3X Touch panel a FAA 2020 WAAS position source and then when "compatibility is extended" this autumn get rid of the GDL 39 and use the GTX 345 for both IN and OUT ADS-B?
Right now I'm facing having to buy a GPS 20A to make my ADS-B OUT work again because, on January 6th 2016, the FAA stopped accepting my G3X Touch's GPS signal as an approved ADS-B WAAS Source. I'd rather not buy the GPS 20A if I'm going to eliminate it again by the end of the year.
Thanks for your help,
-Craig

There is no support to buy a GTX 345 now and replace a GTX 330ES and/or GDL 39 in a G3X Touch system. You will need to wait until the complete development/testing is finished and new system software is released which supports this new device.3) When your website reads, "Compatibility is extended to the G3X?

Hello Craig,
Good questions.
The base 010-01216-01 GTX 345 1090ES ADS-B Out transponder comes standard with built-in dual frequency ADS-B receiver, attitude sensors, and Bluetooth interface. All that is needed with this unit to complete the ADS-B In/Out capability is an external FAR 91.227 compliant position source like the GTN 6XX/7XX, GNS 4XXW/5XXW or the GPS 20A.
The 010-01216-41 GTX 345 w/GPS model is the same as the base model, but adds a built-in FAR 91.227 compliant position source. This model does actually perform all the functions of the GTX 330ES/GDL 39 3D/GPS 20A in one box.
Yes, when the G3X Touch software changes are complete (which are quite extensive), the GTX 345 may be hardwired to your GSU 25 for data and control, and to both the PFD and MFD for a direct feed of ADS-B traffic and weather to these displays.
There is no support to buy a GTX 345 now and replace a GTX 330ES and/or GDL 39 in a G3X Touch system. You will need to wait until the complete development/testing is finished and new system software is released which supports this new device.
Since you now have all of the components needed for full ADS-B In/Out except for the GPS 20A, you could hardly go wrong by buying the GPS 20A now and be done. It's entirely up to you if you prefer to have a GTX 345 w/GPS with everything in one box.
The part numbers listed above are for the panel mount GTX 345 and GTX 345 w/GPS, but there are also remote mount versions of these transponders which may be remotely mounted and controlled (when software development is complete).
Thanks,
Steve
Nice one Steve
So in my case (hardwired 796, GDL39 3D, GTX-327 etc) all I would have to do is replace the 327 with the 010-01216-41 GTX 345 w/GPS and connect to my RS232 daisy chain, remove the GDL39 and I would be good to go for 2020?
Couple of quick questions:
1. Will the existing transponder antenna and cable be OK or will they have to be replaced.
2. I assume the 345 will provide the GPS position to both the 796 and the iPad a la the GDL 39
3. As you are modifying/updating the 796 software dont forget about some of the other punchlist/desires that us 796 owners have discussed with you in the past

Your existing transponder antenna will probably work, but there is a list of compatible antennas in the installation manual, so if you shoot us an email with information on your antenna, we can check.1. Will the existing transponder antenna and cable be OK or will they have to be replaced.
Your GDL39 doesn't actually provide GPS information to the 796. Quite the contrary - the 796 is the GPS rock star and provides this information to the GDL39 which then shares it with a mobile device if needed. Similarly, the GTX 345 does not provide GPS data to the 796.2. I assume the 345 will provide the GPS position to both the 796 and the iPad a la the GDL 39.
Message received. As you can see, we didn't forget about the 796 when the opportunity arose to give it new capabilities to be a great ADS-B traffic and weather display for these new transponders. We are just a little team in a little market, but we do our best.3.

Question for Garmin Experts.
My RV-8 is equipped with a Garmin 430 W Navigator, Garmin GTX 327 Transponder, and an AFS 4500 EFIS.
I want to become ADS-B 2020 compliant and have been saving up to buy and install a Garmin GTX 330ES for that reason.
If I pulled the Garmin 327 and installed the base 010-01216-01 GTX 345 1090ES ADS-B Out transponder standard with built-in dual frequency ADS-B receiver, attitude sensors, and Bluetooth interface and got the latest update on my Garmin 430 W...
1. Could I connect my Ipad with Foreflight or Garmin Pilot using the GTX 345 Bluetooth interface to receive ADS-B in traffic, WX? or do I need Connext to accomplish that?
2. Will I be able to see traffic on the screen of my Garmin 430 W?
3. Will my existing Garmin GTX 327 antenna and coax cable likely work with the GTX 345?
I like the all in one integration in this Garmin 345 offering and it is priced less than a Garmin GTX 330ES.
Thank you,
We appreciate that this "Connext" stuff can be confusing. Both the hardwire and Bluetooth interfaces in the GTX 345 speak Connext protocol, so no, you don't need a FlightStream 110/210 or anything else to directly connect a mobile device running Garmin Pilot or Foreflight to be able to receive and display traffic, weather, and attitude data from the GTX 345.1. Could I connect my Ipad with Foreflight or Garmin Pilot using the GTX 345 Bluetooth interface to receive ADS-B in traffic, WX? or do I need Connext to accomplish that?
Yes, as shown on the "Display Compatibility" page of the GTX 345 web page, the 430W is able to interface to the GTX 345 and display the traffic and weather shown on that web page.2. Will I be able to see traffic on the screen of my Garmin 430 W?

Well this thread is really starting to fire on all 4 cylinders. G3x guys is it to early to release the owner manual and the installation manual for the new transponders?
Well hello Steve from another Okie down south. In addition to Figg's questions about the 796, I have a similar situation but ever so slightly different. In my case, instead of running the 796 I am running a 695 that is hardwired to a GDL39. The GDL39 is feeding the 695 ADS-B In data in addition to feeding, via Bluetooth, that information to my Ipad. The 695 is feeding the GPS data to everything else in my panel. My big dilemma with 2020 compliance is getting a certified WAAS signal in my panel.Hello Dave,
It is always good to hear from our neighbors down in Oklahoma.
Yes, you are correct that the GTX 345 with GPS can be an all-in-one solution for ADS-B In/Out which even replaces the GDL 39 if you want it to. There is even a built-in altitude encoder option (011-03080-00) you can add for $195 if you don't otherwise have this available.
Your GDL39 doesn't actually provide GPS information to the 796. Quite the contrary - the 796 is the GPS rock star and provides this information to the GDL39 which then shares it with a mobile device if needed. Similarly, the GTX 345 does not provide GPS data to the 796.

I have a garmin 320 transponder. Will the garmin 335 tray fit the height and width of that tray? I understand that it is a little over an inch deeper.
I see in the wiring diagram you posted---and repeated below, that the data is transmitted via a rs 232 setup.
Is this data in some secret Garmin code, or is it something that is a standard format that other EFIS brands can understand??

Yes, either the GTX 345 with GPS or the GTX 335 with GPS contain the built in 2020 compliant position source that is missing in your installation.[*]Am I correct in that the 345 will provide the necessary certifiable navigation WAAS GPS signal the FAA requires for 2020 compliance?
The GPSMAP 695 doesn't currently interface to the GTX 345, and we aren't sure if there will be much demand since the GDL39 you have now provides the same ADS-B traffic and weather to your 695 and iPad. You could certainly consider installing a GTX 335 with GPS for ADS-B Out and keep your current dual frequency ADS-B in receiver. The GTX 335 with GPS is $3,795 and the GTX 345 with GPS is $5,795, so you can save $2K if you continue to use your existing GDL39 for ADS-B In.[*]Will the 345 feed all ADS-B WX and Traffic information to the 695 and the Ipad? If so, will I be able to use the exisiting hard wire connections I have in place or will I be required to change out the existing hard wiring for something else?
Yes, the GTX 345 includes a Bluetooth interface that is supported by Foreflight to receive traffic and weather.[*]Will the 345 feed all ADS-B In data (WX and Traffic) to Foreflight?
We don't currently see the FAR 91.227 compliant position source built into the transponder as satisfying the IFR flight requirements for a certified WAAS GPS IFR navigator like the GNS or GTN.[*]There has been talk on here about legal navigation using a certified navigation instrument in order to comply with legal IFR filing. Could you expound upon the concept of the prospect of having a unit such as these new 'all-in-one' units providing that capability? Is this an unrealistic expectation, or is this a realistic possibility?
Hello Mike,
The serial ports on the GTX 345 support a number of different serial formats - some new, some legacy, some only used by Garmin products, some by others.
Thanks for your interest,
Steve
Steve, thanks for the info. All very good. As for the 695, maybe its time to think about upgrading.Hi Steve,
Good to hear from you again. About time for some more Kansas BBQ at K81 We-Be-Smokin on the way back from Oshkosh....

Garmin Experts,
Configuration:
Garmin GTX 345 Transponder, Garmin 430W Nav/Com and a compatible mobile device (Ipad) running Garmin Pilot or Foreflight.
1. Can I push a flight plan from a compatible mobile device running Garmin Pilot or Foreflight to the Garmin 430W?
Thank you,
Hello Charlie,
We are checking on this and will update this posting when we have an answer.
Thanks for your interest,
Steve
Steve,
I have the same question regarding the 430 (non W). Can you push flight plans to it, and also can you display targets on it?
Hello Charlie,
You would need to install a Flight Stream 210 unit connected via hardwire to both the GNS and GTX 345 to be able to send flight plans to the GNS 430W.
The Flight Stream 210 will receive attitude, traffic, and weather from the GTX 345, so your mobile device would have just a single Bluetooth interface to receive this data and share flight plans.
When the Flight Stream 210 is installed, you will need to turn off the Bluetooth interface on the GTX 345.
Thanks for your interest,
Steve
My setup:
GNS 480 and MX-20 display (basic, no chartview or old school traffic).
What are my options with the new transponders and Garmin Pilot? Can any of them be remote controlled by the 480 like the -330 can?
Thanks!
Can the installation and operation manuals for these be made available?
I'm more interested in the 335.
Thanks,
Dave
So given that Garmin is providing these units to EAB builders to install into their Experimental aircraft you are saying that we still have to go to a Garmin dealer/installer in order to see/view/utilize an installation manual even though we are not required by any regulation to have said installer install our unit? If we are installing these units in our experimental aircraft ourselves you are saying we are on our own to figure it out OR pay the piper and have a Garmin dealer install it? Not sure what to think about this issue of not being able to gain access to the installation manual.Hello Dave,
unfortunately no, we're still obtaining STC approval and the manuals are not completed as of yet. these will be available to your local Garmin dealer hopefully by late next week.

Hi Steve, So when will these units (GTX 345) actually be available from the avionics dealers for sale and installation?

Question to Steve:
The GTX 345 Installation Manual states that a fan is not included or needed. The mechanical drawings Figure B-2 shows a VENT opening in the unit and the rack.
Question; is this vent opening only used if a fan is used on the back of the chassis, or do I need to mirror the vent opening in my radio stack side plates?
Has there been any news when this unit will be released?
Question to the experts:
It looks like I will be replacing my America-King blind encoder (outputs Gray code). The GTX 345 can be optioned with a pressure sensor module (011-03080-00) and it attaches to the Static system in place of the blind encoder.
So, the Txponder gets the needed altitude info. Does the GTX 345 also output this info in a RS-232 interface or ARINC interface available to other devices?
Thanks.
Any news on the Gtx345?
