Garmin GTR 200 Panel Mount COM Radio
Overview
Important Notes:
The GTR 200 is the first to integrate advanced audio panel features like a two place auto-squelch stereo intercom, which senses the amount of sound in the cockpit and automatically adjusts the mic squelch for effortless intercom use regardless of the cockpit noise level. With 3D audio, the GTR 200 makes it easy to discern between the active and monitored standby frequencies as well as the other passengers. The radio’s best-in-class standby monitor is enhanced with patent-pending digital processing, so it seems as though there are two radios in one. With its advanced integration with the Garmin G3X glass flight display, or other compatible Garmin portable products, the GTR 200 is able to receive a frequency and identifier in the comm’s standby position directly from the G3X’s waypoint page, allowing the pilot to ensure accurate transfer and reduce workload. This same integration, automatically, and without the need for a database, displays the airport identifier and type on the GTR 200, like “KOSH ATIS” should the pilot manually tune the frequency. And further, these compatible Garmin portable products, constantly stream the flight plan and nearest airports to the GTR 200 for quick access and retrieval of any airport frequency with a single push of the knob. Accessing these features on the GTR 200 is extremely easy and intuitive, with a sunlight readable display and built-in shortcuts including configurable soft keys to help reduce cockpit workload (for example, configuring one-touch access to music mute or pilot isolate). Optionally installed switches, typically on the flight controls, allow pilots to keep their hands on the controls while performing functions like swapping active and standby frequencies. And for easy retrieval of the most commonly used frequencies, the GTR 200 stores up to 20 pilot-defined frequencies as well as the 20 most recent frequencies used for easy retrieval. The radios are easy to install, with a standard density 37 pin connector and they support both 14 and 28 volt aircraft and offer 25 kHz channel spacing. List of compatabile Garmin Products:

Great radio
Verified Purchase
GARMIN GTR 200 COM RADIO 10 WATT 25 KHZ SPACING NON TSO
I ordered this to replace a 14 year old Garmin SL40 that was functioning as Com 2 but had fading reception and an inop volume control. The only connections the GTR200 needed were the external antenna, power, ground, and five wires going to the audio panel. Fabricating a new wiring harness was made relatively simple by the fact that during the original build, I had positioned in-line connectors (DB9 or DB25 computer connectors, to be exact) in between all avionics in the stack and all other units. So it was only necessary to terminate the new wiring in a DB9 connector that matched the pinouts of the original wiring. A bonus of having the new unit is that it has a 10 watt transmitter vs. 8 watts for the old one, and a much more informative digital display e.g., when monitoring two frequencies at once, it shows which one is receiving a transmission at the moment. A minor annoyance was that Garmin radio trays apparently now are just a smidge wider than they used to be. The standard 6.25 inch width has now become 6.30” – just enough that new trays won’t slide easily into stacks of older radios without some creativity with a flat file to make the opening a bit wider. Luckily the height of the GTR200 is the same as the SL40 (even though the Garmin specs say it isn’t!) so neither the GNS480 navigator above the radio or the GTX330ES transponder below it had to be moved. Oh, and the new unit works great. : )

Garmin 200 is great radio. I got the harness with the jacks. The harness is absolute jewelry. Every wire labeled, everything professionally wired. You won’t get a better harness and you won’t find any shop that can do it cheaper.
I have purchased and installed three of these units in different aircraft and I absolutely love them. Be sure and buy the harness from aircraft Spruce and you will not be disappointed. All the wires are clearly labeled and very easy to install probably only takes me 30 minutes to install one now.
Quick service. Thank you
I deal with Spruce on a regular basis and always find the people and the service to be exceptional.
excellent service
Gamin logic, Garmin build quality (though actually in Thailand). I ordered mine with the made up 4ft harness with headphone jacks. This was a replacement radio for an MGL Transceiver. Total install time in a Sonex to remove old radio and harness, alter panel, fabricate a holder for the tray, install and wire in new harness - 8 hours. Including audio interfaces. Did not interface with EFIS data but did interface with EFIS audio alerts. (would have added about another hour to wire the data - but the EFIS may not remain in the aircraft long so....). Would have been many hours longer if I had made my own harness. Harness worth the extra $$ Installation manual is emailed to you by Aircraft Spruce after verified purchase. Configuration time after install - about 30 mins to run through it and make your choices. In service - people hear me fine, the radio proved much more sensitive on my existing antenna - leading me to believe that other brand was OK - but had not been doing me any favors. 3D setup is a nice touch. Intercom is stereo. For $$ - better featured than the other brand for slightly less $$ Penalty is weight. About 1lb heavier once installed. Ill take the 1lb for the added features and sensitivity. Sound quality of interface to a Gamin VIRB camera using the VIRB Audio jack adapter - excellent. If you are a builder/comfortable doing wiring - this install is quite straightforward (again - the pre-made harness is a huge help). The only bit you probably need outside assistance with is the output test - I had to borrow equipment for that. Would definitely buy again.
Good service

No, the GTR 200 is not a direct replacement for the SL 40 as it requires a new installation.
Total product footprint is 1.35” tall by 6.25” wide. Has only a 9.4” behind-the-panel depth including connectors (8” without connectors), 1.34 lbs (1.91 lbs. with rack and connectors).
Yes, Garmin still allows this feature in the GTR 200.
The Garmin GTR 200 can be used as the com radio for a Skyview system but does not connect to the Skyview to show com frequencies on the Skyview display.
No, it will not fit as you will have to do a new installation with the GTR 200.
No, this will not side into the Narco 810. Also note the GTR 200 is not a certified radio and is intended for experimental aircraft only.
There is not a 3.5mm jack on the unit as the music source is from the back of the unit and you attach the 3.5mm jack to it.
Yes, the date out line from the Aera will go to pin 24 on the GTR 200 (RS 232 In).
Per Garmin: Yes, it will.
The Garmin GTR 200 Panel mount Radio Standard Kit comes with Rack, Connector Kit, and Back plate. The Standard Kit + Harness" model includes all the same with the addition of the harness.
