Garmin GMR 404 Open Array Issue

[abacodan]

Before I get on hold with the Garmin techs- our three year old Garmin Radar began powering up intermittently. Sometimes just powering down the 3210 and powering back up would bring it up, other times it would not come up at all, and now the 3210 behaves as though the radar does not exist at all. Any input on this or anyone else have this issue?
Thanks in advance.....

If it doesn't see the radar, it means 1 of 3 things: the connector cable has gone bad; the pedestal isn't getting enough power; or you have a problem in the pedestal that Garmin will need to fix.

I had problem with my pedestal. Tech open up a cover and water poured out! I think this may be a problem with some of the first units. Check for water intrusion.

some install and cover the weep hole allowing water to collect inside...
