The rubber on the antenna of my GPSMAP 67 is damaged, it looks like a small cut on one of the corners, see photo.

Now I’m wondering if this will give any issues with water resistance? I’m in Norway at this moment and it is raining a lot

And I’m a bit surprised it’s already damaged as it is always in the Garmin case when it is in my backpack and neither can I remember something that could cause this… Already contacted Garmin support, let’s see what they will say.

Looks the same as when my cat chews on things I leave out.

Is it punctured all the way through?

Open the barometric pressure graph and apply some pressure to the suspected location and see if the value on the display changes in response.

If I had a cat (or any other pet) it would be an easy explanation!

I cannot really see if it’s punctured all the way through.

Pressing the puncture does not seem to change the barometric pressure value so I guess that means it is not fully through?

You need to introduce a light to moderate air pressure change in the area of the puncture, not press on it.

How you do that is up to you.

It looks like the TUSITA case for the 67i completely shrouds the antenna. That might be an option if Garmin doesn't help out. Of course, there will be a small open space on the side of your 67 as it does not have an SOS button. As seen in the GPSrChive store.

Almost, but not quite, apparently:

Perhaps a carefully applied (toothpick) dab of ShoeGoo or similar rubber repair would fix this issue.

Well that gets a bit too complicated for me

So I did a different test and took it out for a hike today with plenty of rain and the unit seemed to work just fine

That might be an option, but I’ll first wait and see what solution Garmin can offer.

Replace the balloon with GPSMAP

Thank you!

Also, create positive and negative pressure pulses in succession and then check the barometric pressure graph to see if there was any response.
