Charger terminal corrrosion during spring

I live in upstate NY and have a Garmin 65 LMT with the standard
charger -- TA 20 P/N 320-00239-70.

I bought the unit about 5 years ago. I leave it and the charger
in the car all the time. After the second spring, I noticed that
the metallic tip of the plug that goes into the GPS was corroded
and all the contacts were gone. I bought a replacement charger.
Last weekend, I found that the same had happened to the
replacement charger.

Now, my questions.

1) Has anyone living in the colder parts of the world had a
similar experience?

2) Since it seems to happen only in the spring, when the
temperatures are rising, is there some condensation going
on the causes the corrosion? I keep the charger in the
closed storage compartment between the front seats,
but not enclosed in something like a zip lock bag.

From now, I intend to bring the charger into the house,
but it is a real nuisance as one never knows when one
needs it! But, finding that it is corroded just when
one needs it is just as irksome!

Any tips to prevent the corrosion while it sits in the car
would be most welcome.

Put the charger in a zip top plastic along with a hand full of dry
uncooked rice.

Thanks!

Good idea. I was thinking about the the little silica-gel bags that
often come with stuff.

The interesting thing is that, so far, for me, it has happened
every *other* spring!

I think that I will give this trick a go. If the charger lasts another
two or three years, it will be time to get a newer GPS as it would
be about 7 years old by then.
