Radar Overview
The Garmin GMR 404/406 transmits a narrow beam of microwave
energy in a rotating 360° pattern. When the transmitted energy
contacts a target, some of that energy is refl ected and returned to the
scanner. The scanner collects the returned energy for processing and
display. The GMR 404/406 is operated and adjusted using controls
on the Gamin chartplotter. Radar data is presented on a dedicated
Radar Page or as an overlay on the Map page. All radar controls are
accessible on both pages.
The Radar Page
With the GMR 404/406 radar properly installed, at power up, the
Garmin chartplotter should detect the GMR 404/406 as a new
network connection.
Note:
A
software update may be needed for the GMR 404/406 to
function properly. If the message “Incompatible Software
Version” is displayed when the chartplotter is powered on, the
software in the chartplotter needs to be updated. A software
update card is provided with the GMR 404/406.
When the new radar is detected, the chartplotter automatically
adds a dedicated Radar Page to the pages list. If the Radar Page is
not available, press and hold
ADJ/MENU

displayed. Use the
Rocker t
