In other words, a G3X system is not required to hear these alerts for the GTX 345/345R.

And yes, the GDL 88 also provides this type of traffic aural alert.

Thanks,
Steve
Thanks for your clarification Steve. So that means for 2020 compliant ads-b out, with audio traffic alerting, without sacrificing anonymity in 1200, the gdl88 is garmins only option, correct? Assuming a device such as a GTS 800 is not included.

I had heard one pirep of the gdl88 where the pilot stated he didn't receive these alerts often. Does the gdl88 have set up parameters of alert areas I.e. only alert within certain altitude and range? Or does that have to be setup within a connected device such as the 430W or 496 I have in the plane?

Please advise
Thanks
Steve

Well, my name is Steve also so I will offer this: There is the gdl82 for ADS-B OUT UAT that has anonymity. Of course it has no ADS-B IN so you would have to combine it with the GDL-39 or GDL-52 to get IN capabilities and provide your aural alerts.

Hey Steve

Do the gdl39 and or gdl52 send aural alerts directly to the audio panel or through an efis or tablet etc? Can those alerts be setup for proximity within the gdl?

All aural alerts come from whichever display unit one would use to display the traffic. That would be EFIS displays of whatever manufacturer you choose to use, GPS displays of whatever manufacturer you choose to use, moving map displays of whatever APP manufacturer you choose to use that is running on whatever tablet from whatever manufacturer you choose to use.

In my case I have a Garmin GDL-39 sending ADSB-IN information to two distinctly different instruments, a Garmin GDU470 and an Ipad running Foreflight. Those two units are in turn sending individual and separate audio signals through hard wiring to a Garmin GMA245 audio panel.

There are no audio connections directly from the GDL-39 to the GMA245 audio panel. The GDL-39, or any other ADS-B IN unit, is only providing specific DATA, in a specific standardized format, to the various other instruments that either display that data visually, or aurally, or both.
