Garmin GDM 450R - 010-02620-31
Garmin GDM 450R is a digital, remote-mount DME radio for Part 23 general aviation aircraft that provides slant-range distance calculations to DME ground stations. It follows associated NAV radio tuning and is intended for aircraft using select Garmin integrated flight decks and displays.
Precision Distance Information
Maintain slant-range distance information relative to DME ground stations. The remote-mount design brings modern digital DME capability to general aviation installations.
Flexible DME Tuning
Tune and track up to two separate DME frequencies. With optional enablement and compatible avionics, FMS1 can automatically scan and tune up to three additional DME frequencies.
Retained DME Reference
Keep the active DME distance indication with DME hold while tuning the associated NAV radio to another frequency. This can be useful during instrument approaches when a localizer or other approach aid must be selected.
DME-Based RNAV Support
With a compatible flight deck or display, the GDM 450R can use distance data from two or more DME ground stations to determine aircraft position. This supports DME-DME area navigation (RNAV) routes as an alternative navigation option.
Display And Indicator Connections
The GDM 450R integrates directly with compatible Garmin displays without an interface adapter. RS-232 and King Serial interfacing are also supported for connection to legacy distance indicators.
System Configuration Considerations
An L-band DME antenna, sold separately, is required to complete a GDM 450R system installation. Feature availability varies by display and requires a compatible Garmin system.

FLY WITH PRECISION DISTANCE MEASUREMENT
Designed for Part 23 general aviation aircraft, the GDM 450R remote-mount DME works with select Garmin integrated flight decks and displays to provide slant-range distance calculations relative to DME ground stations.
THE DME SOLUTION FOR TODAY’S GA AIRCRAFT
GDM 450R DME is a modern digital radio, designed for installation in general aviation aircraft. It’s a remote-mount unit that follows the tuning of associated NAV radio(s).
MULTICHANNEL OPERATION
GDM 450R can allow pilots to tune and track up to two separate DME frequencies. With an optional enablement and compatible avionics, the aircraft’s FMS1 can automatically scan and tune up to three additional DME frequencies.
DME HOLD CAPABILITY
For added navigation flexibility, the DME “hold” function lets you maintain your active DME distance indication when tuning the associated NAV radio to a different frequency. This function is particularly useful for instrument approaches where it becomes necessary to tune the localizer or other approach aid while needing to retain your NAV’s referenced DME information.
DME-DME AREA NAVIGATION (RNAV)
With a compatible flight deck or display, the GDM 450R radio can use the distances from two or more DME ground stations to determine the aircraft’s position. This enables the DME to support RNAV routes, providing an alternative navigation option.
EASY INTERFACING
For seamless installation, GDM 450R integrates directly with compatible Garmin displays — no interface adapter is required. It also supports RS-232 and King Serial interfacing to connect with legacy distance indicators.
COMPLETING THE SYSTEM
In addition to compatible navigation equipment and flight displays in your aircraft, you’ll need an L-band DME antenna (sold separately) to complete your GDM 450R system installation. See your Garmin dealer for recommended antenna options and mounting configurations.
Environmentally Hardened
GDM 4500 is designed for high performance turbine aircraft and helicopters.
