No. I don't think the Garmin GTX 345 can interface that way with the AFS 4500. Maybe Rob Hickman or his staff at AFS could answer that question.

However, I understand the GTX 330 offers a Traffic Information Services (TIS) interface when connected to the the AFS 4500. It requires connection between GTX 330 serial port #1 to the AFS 4500 EFIS serial port #2.

I digress.

My GTX 345 is wired to my Garmin GNS 430 W and I should see traffic and WX but honestly when I flew yesterday I didn't think to look for traffic on the 430 screen.

The Bluetooth connection between my GTX 345 and Apple Ipad Mini running Foreflight works well. It's really surprising to look at Foreflight and see how much air traffic is out there around you that I can't actually see when scanning outside.

I have a Garmin Aera 660 coming. Looking forward to testing that out as well.

Off-topic, my other option is Freeflight connected to the AFS (which is verified to work), but I haven't yet determined if the Freeflight will feed G3X Touch, should that be the direction a future panel update takes me.

Freeflight was an option I consider as well. I choose Garmin because I too I'm seriously considering an eventual change from the AFS 4500 to the Garmin G3X Touch. The decision to get the Garmin GTX 345 now was based on that and a couple of other things.

1. Foreflight
2. I could get all the benefits of ADSB in/out and still be able to interface with a G3X down the road (3rd quarter).
3. All-in-one.

I did not want a remote transponder. I like my transponder right there in the panel where I can readily push the buttons. I'm thankful Garmin offered this solution. I swapped a GTX 327 for a GTX 345. They look almost exactly the same except the screen on the GTX 345 is nicer in my opinion.

I really like that I only need one transponder antenna with the GTX 345. That one antenna transmits and receives ADSB. Pretty cool.

Had I gone for the GTX 335 and the GDL 39R solution I would have needed a receiver antenna for the GDL 39R.

GTX 345 Bluetooth Pairing
 
Hey Garmin Experts,
Installing the GTX 345. It has no Bluetooth function under the System(SYS) Menu group even though it is enabled in the installation configuration.

Also, the GTN will not allow interface configuration of RS-232 GTX w/TIS+ #1.

Where did I go wrong?

Hello Kent,

For a GTX 345 not being controlled by a GTN, the "Bluetooth ON" selection on the system page is the 4th page down just past "Messages".

For a GTX 345 controlled by a GTN (V6.11 or newer GTN software), the Connext Setup page on the GTN supports the addition and management of Bluetooth paired devices for the GTX 345. Page 15-48 of the Rev. K GTN 6XX Pilot Guide provides an explanation of this feature.

The GTX 345 uses RS-232 "REMOTE FMT 1" for control via the GTN. The GTX 335 supports TIS-A traffic, but the GTX 345 does not since it supports ADS-B traffic.

An Ethernet (HSDB) connection between the GTN and GTX 345 allows the GTN to both send ADS-B+ GPS position data to the GTX 345 and receive ADS-B traffic and weather.

Please contact us directly if you have additional questions.

Thanks,
Steve

Once you have the gtn and gtx talking correctly you will pair the bluetooth of the gtx through the connext page in the gtn. Seems a little backwards i know, and you don't want to know how long it took me to figure that little one out since it's not spelled out anywhere in the gtx manual.

Is there a minimum hardware/software revision needed for the GNS430W to work with a GTX345? If so, what is involved in getting it updated?

Thanks! Larry

Larry,

Yes software. I removed my GNS 430W and brought it to a Garmin Dealer. I explained I was installing the Garmin GTX345 Transponder and needed the most recent software update so my 430 would talk to my 345. They had done a few GTX345 installs and in addition to the software update (I think version 5.30V) they also configured my 430 to interface with my 345.

GTX 345 software updates
 
I purchased & installed the GTX 345 in Nov 2016. At the time I was told that we home builders could not perform any software updates to the 345, only dealers could do it. Has that changed?

I could not find on the Garmin website what the current software version is. In my 345 I have v2.03 XPDR, 2.02 ADSB & 6.0 GPS. I do not no if these have been updated or if still current.

Steve or anyone, is my unit current? If not, do you know if Garmin will be at the AOPA fly-in at the end of April in Camarillo, CA & be performing updates if I bring the unit to them?

If one gets the GTX 345 with GPS - can that GPS be used as a source for other devices - specifically I was wanting to now if it can be used by my 406 ELT as a GPS source?
