Garmin GTR 205 COMM Radio

Adding advanced communication capabilities to any panel, the GTR 205 is an optimized and cost-effective solution. The 2,280-channel capable VHF COMM radio comes standard with 10 watts of power, and a 16 watt option is also available. For operators requiring NVIS compatibility, there is an option for that as well. Additionally, pilots can monitor a standby COMM frequency while tuned to the active frequency, allowing them to perform various tasks such as listening to ATIS transmissions without leaving the active ATC frequency. 
The worldwide frequency database makes it convenient to find frequencies by searching an airport identifier. Frequency memory and instant recall make tuning to the most often or recently used frequencies quick and efficient, plus holding down the volume knob will quick-tune to the emergency channel 121.5. To assist with approaches, holds or other assigned maneuvers, the GTR 205 includes a built-in timer, with the option to count up or count down.


Upgrade your COMM radio with the modern, cost-effective slimline GTR 205 radio, and add advanced communication capabilities to your panel.

- Small panel? The slim 1.3” height fits your aircraft with ease.
- See your frequencies clearly on a large, bright, full-color LCD display.
- It’s easy to use, with a familiar, intuitive interface.
- Find your navaid or facility frequency with the worldwide database.

The 2,280-channel capable VHF COMM radio offers standard 10 watts (or optional 16 watts with enablement) of transmit power plus pilot-selectable 25 kHz or 8.33 kHz channel spacing and automatic or manual squelch. Swap your active and standby frequencies with a single touch of a button.


Enter an airport identifier, and let the GNC 215 radio look up frequencies for that location (tower, ground, ATIS, clearance delivery, etc.) from its worldwide database. Then send the selected frequency to the standby position.


Pair with your compatible GPS source to enable frequency ID and show your tuned frequency’s identifier and type, including tower, ATIS, center and more. So you always know who you’re talking to.


Listen to a standby frequency, such as ATIS, without leaving your active channel.


With frequency memory and recall, you can quickly tune your most frequently or recently used frequencies. Plus, holding down the volume knob will dial up the 121.5 emergency frequency.


Use the built-in timer to assist with approaches, holds and other assigned maneuvers — with the option to count up or count down.


For demanding night missions, GNC 215 is available with an optional NVIS enablement.


Pair the GNC 215 radio with your G3X Touch flight display, and remotely tune your radio via your flight display touchscreen.
