In search of Garmin Radar Dome

Hello Tug Nuts.

Wondering if anyone has a decommissioned or soon-to-be-replaced Garmin GMR-18 or GMR-24 radar dome you'd like to part with? The radar on my Garmin 5212 chart plotter stopped working a few months ago and I suspect it is the radar dome since everything else works on the plotter and I have run all the typical tests for power to the dome and on the network cable. This is an older unit of about 2010 vintage. Garmin no longer makes this unit, but I am trying to restore the system as it worked really well for me.

Thanks,

Lee

The weak item on 5212 domes is the network connection. Check the cable end very carefully and the socket it connects to. There was a problem with a very small, fragile o-ring that protected the connection from corrosion. Must make sure that all the copper strips on the cable and in the socket are there and not gone or corroded. If the socket is the problem, it is easy to replace - the dome comes apart - very simple inside to change out the socket - can get one from Garmin or ebay. If it is the cable end - that can be replaced too. Usually it is both. If just light corrosion - carefully clean up and fill socket with non-conductive gel to prevent new corrosion.

Will do. Thanks very much.
