Default Beware Garmin Radar

Garmin 18xhd bought 8-2016. Not installed til 2017. Gave 1024 error code , then 5 minutes later it doesnt show up on gps. Called garmin and they could fix at a minimum of $900 since just outside 2 yr warranty. Told me to not take dome off because they would not fix if i did. For $900 , i had nothing to lose. Take off ttop and i can hear water in dome. Take dome off and sure enough , water and rust all inside. Beware of Garmin radar quality . In this case , the seal. I wish garmin would do the right thing in these situations. A waste of money to say the least. Hope this helps future radar buyers to stay away from Garmin. Unless you want to buy a new one every 2.5 yrs

Wow, that's bad. Where the heck did you store that radar before it was installed... in your swimming pool?!
I have a Furuno DRS4D-NXT unit from the same exact timeframe. It still works great but now want to pop the cover off the radome to see what it looks like.

I have a 24hd that's about 8 or 9 years old with zero issues. And it is not in a dry location by any means.

Not that it can't happen, especially if someone opened the unit at some point and pinched a seal. I've seen people who flush mount them open them up so they can screw them down into a hardtop rather than bolt up.

Radar kept inside house before install. Once on the boat, it has stayed in my driveway unless used. Maybe 15 times a year. Nought directly from garmin

In my experience the manufacturing quality control is very low for Garmin radars. When I put an 18HD on my boat the first on came with parts missing inside. It could not possibly have passed any tests at the factory, yet it was shipped.

Might be a good idea if you're a Garmin owner, to pull the lid before the warranty is up. I wouldn't be a happy camper.

Thankfully it didn't fail at critical time.

Maybe a pelican sat on the lid and cracked it

When installed was a torque wrench used to tighten the fasteners?
Over tightening can cause housing to twist or distort and o-rings become unsealed.
Garmin states "Using a torque wrench, tighten the nuts from 13.7 to 18.6 N-m (10 to 14 lbf-in.) of force"
With that much moisture I would expect a close visual inspection to show something? Crack in unit somewhere? Grain of sand on O-ring? You don't see any indication where the water came in at?

Water intrusion on radars is not limited to Garmin...

Damn!!!! This is interesting because mine JUST failed “error 1024 AFC calibration required”.


Do i do I even bother with all the troubleshooting they asked me to do or just send it in?

Mine was bought/installed 8/30/17 so I’m only just inside the warranty period.

This is aggravating and I hope that $900+ gets waived.

Default Radar

Lookimg from the outside, it would seem impossible to leak. No cracks or amy other sign of a flaw. Somehow, someway it must suck humidity/moisture inward I'm assuming around the gasket. When i took it off ttop and tilted it to take down, i could hear water inside. Im baffled . And yes quality control missed this one . If it is such a fluke, garmin should make it right. But as of now no im out the $$

That sucks. It looks like saltwater in one of those pictures. That would screw up a circuit board in real short order.

escalate at garmin, ask for good and all you want to do is send it to them and have it fixed

I have an GMR18 that worked ok on short ranges, quit working and showed an error code #6. Radar had about a cup of water inside. I'm thinking condensation. I've dried it out for a couple of days, we'll see how it acts when I put it back together.

I have an 18xhd that has been in service for over 5 year now with zero issues but I mounted on a flat plate and followed the torq spec guidelines for attachment. If they are mounted on a slightly uneven surface the probability for seal failure is exponentially increased. The same is for all makes of dome radars and is a common cause of water intrusion failure. The use of pressure washers by boat yard detailers have killed a few domes as well.

If you want any kind of warranty from water intrusion on a radome it needs to be installed by a product certified installer. If you do it yourself you are on your own and it won’t be covered.

Pretty sure warranties can't require that...please highlight that language in the warranty for us to read

If there is proof you improperly installed it, then sure they have a way out...and I have seen plenty of "certified installers" do absolute crap/incorrect installations too....specifically over-tightening things that should not be over-tightened.

You just provided Garmin with about $5,000 of free negative advertising. I believe they earned every penny of it

That I believe is or at least should be NONSENSE! A radar dome should be designed to be installed by the buyer without the water problem displayed. I think this was improperly put together by Garmin! This for sure, those who have read the OP's post and saw his pictures will have new thoughts to their planned Garmin radar purchase.
