Add to Wishlist


Designed for both fixed-wing aircraft and helicopters, the GTR 205 is a versatile radio that can serve in a variety of aircraft types and panel installations. The 1.3-inch height form factor matches previous-generation SL30 and SL40 radios, enabling easier upgrades and creating more room in space constrained panels. Pilot-selectable 25 kHz or 8.33 kHz channel spacing provides global capability. The radio features a sunlight-readable color LCD display, indicating the currently tuned active and standby frequencies, as well as their station ID such as KOJC TWR or KSLE ATIS. The vibrant display as well as the dual concentric knob and backlit keys mimic those found on other modern Garmin avionics products, providing an intuitive user interface and simplifying product operation.

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. 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.
