SEAVIEW GARMIN MOUNT
Our SEAVIEW Garmin mount was designed to fit the GMR20 and GMR40 28” radomes. If you have purchased a
GMR21/41 radome our mount will still work nicely. To properly install your GMR18, GMR20 or GMR40 to our
Seaview mount, you will be required to rotate the radome 180 degrees. Once installed the Garmin GMR18/20/40
softwarecan simply adjust the radar heading by 180 degrees. To accomplish this, please follow the instructions in
your GMR18, GMR20, GMR40 Owner’s Manual as duplicated on our 2nd page.The following illustrate how the
GMR18, GMR20 and the GMR40 should look once installed to our SEAVIEW Garmin mounts. See Fig.1, 2, 3 and 4.
