I have what I beleive is an M1720 or M1730 Radar system that was OEM from Sea Ray in my 1998 400 Sundancer. I am looking to replace the old CRT display and wa told that a newer RDP-139 would work with my Pedastal and Array. Can someone point me to the RDP-139 installation and operations manuals? I see in this forum that the RDP-139 was part of the GD1900 radar system but I can't find manuals for either product number. Thank you.
