Garmin GTR 205 — COMM Radio for Experimental Aircraft - 010-03395-01
Garmin GTR 205 is a slimline VHF COMM radio and audio solution for experimental aircraft, combining communication, intercom, and entertainment functions in one panel-mounted unit. Its 1.3” bezel height, full-color LCD display, and frequency-management tools make it a practical option for aircraft owners seeking modern COMM capability without adding separate audio equipment.
Efficient Frequency Management
Reduce tuning workload with airport frequency lookup, frequency memory and recall, standby COMM monitoring, and one-touch active/standby frequency swapping. Holding the volume knob selects the 121.5 emergency frequency.
Integrated Crew Audio
Communicate through the built-in two-place intercom, expandable to four place with optional software enablement. Auto squelch, pilot isolate, 3D Audio processing, EQ settings, and optional COMM playback support clear audio management.
Flexible COMM Capability
Use the 2,280-channel capable VHF COMM transceiver with pilot-selectable 25 kHz or 8.33 kHz channel spacing. Standard transmit power is 10 watts, with optional 16 watts available through enablement.
Frequency Awareness And Control
Enter an airport identifier to find location-specific frequencies from the worldwide database, including tower, ground, ATIS, and clearance delivery, then place a selected frequency in standby. When paired with a compatible GPS source, frequency ID can display the tuned frequency’s identifier and type, such as tower, ATIS, or center. A built-in count-up or count-down timer can assist with approaches, holds, and other assigned maneuvers.
Panel And Display Integration
The full-color LCD presents radio and connected-device information in a compact form factor. Pair GTR 205 with an AXIS™ Flight Display or G3X Touch™ flight display to tune the radio remotely from the flight display touchscreen. Optional dual-COMM switching allows the unit to function as an audio panel for talking on and/or monitoring a second COMM radio.
Connected Audio Options
Bluetooth 5.0 connectivity supports A2DP and AVRCP for music and HFP for phone use, with one connected device at a time and storage for up to 8 paired devices. The display can show song and artist details, phone numbers, device signal strength, and battery life, while the radio controls play, pause, skip, repeat, and call functions. Supported music sources include phones, tablets, GDL 51/52, and Garmin watches such as D2 Delta; firmware updates are free and field loadable by micro-SD card.

FIND A FREQUENCY
Enter an airport identifier, and let the GTR 205 radio look up frequencies for that location (tower, ground, ATIS, clearance delivery and more) from its worldwide database. Then, send the selected frequency to the standby position.

FREQUENCY ID
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 know who you’re talking to.

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

INSTANT RECALL
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.

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

NVG COMPATIBLE
For demanding night missions, GTR 205 is available with an optional NVIS enablement.

REMOTE TUNING
Pair the GTR 205 radio with your AXISTM Flight Display or G3X Touch™ flight display, and remotely tune your radio via your flight display touchscreen.

BUILT-IN INTERCOM
Communicate clearly with your co-pilot via the built-in two-place intercom, which is expandable to four place. The pilot-isolate feature allows you to focus on COMM radio communications without interruptions.

AUTO SQUELCH TECHNOLOGY
Auto squelch allows GTR 205 to automatically sense noise levels in the cockpit and adjust the mic squelch for easy intercom use regardless of the cockpit noise level.

3D AUDIO PROCESSING
With your stereo headset, hear each audio source as if it’s coming from a unique location — so it’s easier to differentiate between sources.

BLUETOOTH CONNECTIVITY
Pair with your smartphone or other compatible device to stream music and see song and artist on the GTR 205 display — and play, pause, skip or repeat tracks without needing to access your device. Plus, receive incoming calls, view phone numbers, end calls, and see your device’s signal strength and battery life right on the display.

EQ SETTINGS
Music settings allow you to select enhanced bass boost levels as well as equalizer effects that include rock, classical and pop audio profiles.

DUAL-COMM SWITCHING
Connect a second COMM radio via an AUX input. Switch between either radio — or monitor both at once. In event of a power loss, a backup mode will automatically connect the pilot’s headset to the second radio.

COMM PLAYBACK
Record up to 150 seconds of prior transmissions. Easily browse clips and playback clearances, missed radio calls and more. Customizable softkeys make it easy to access transmissions.
