With their super-narrow beamwidths and 4 kilowatts
of power, the Garmin GMR 404/406 series offer
outstanding clarity, precision and target definition.
As an aid in locational awareness, the GMR 404/406
radar image can be overlaid on the Garmin network’s
moving map cartography display.
A split-screen view allows simultaneous display of
mapping alongside the standard radar picture.
