I am in the process of trying to get Humminbird to take back under warranty [some product of theirs which has a fogged display]. They are saying that some fogging is normal. I however am experiencing excessive fogging that lasts up to two hours or more in colder conditions. I wonder if it is more prevalent in northern lattitudes like New Hampshire where I fish. Humminbird claims that they have not had many complaints.
If anyone was able to get a solution to the problem or refund with the company let me know.

I had the same problem with a Lowrance depth sounder. The dealer took it back, without question, and replaced it with a new unit from inventory. Cost to me: zero.

Devices that generate a lot of internal heat may burn off the fogging faster. On the other hand, nothing preserves electronic devices like running at cool temperatures. Maybe the Humminbird fogging problems are due to it not generating enough internal heat.

I've had a Humminbird get a fogging on the inside that wasn't
condensation. It was some sort white coating, and on one
side only. It was way out of warranty, so I carefully took
it apart, cleaned the inside of the window (paper towel and
Windex, IIRC), and carefully put it back together.

My unit is under warranty but they will not give a refund. They will only "service it" but I think that it is a chronic problem with Humminbird. If they give me a new unit I'm afriad it will do the same thing.
They state on their web site that some fogging is normal. Others on continuouswave have said that that also, but I am experiencing excessive fogging. Again, I think Humminbird is just trying to dodge a product line defect.
The strange thing is that [fogging] did not seem to [occur] in the warmer weather in early summer. Once fall came [fogging] became much worse and the entire display would be fogged for two hours.
Has anyone had a fogging problem with Garmin? If not I am going for one of those once I get rid of the Humminbird.

If the condensation is fogging, it needs cool weather, not
warm. You may be able to make it go away more quickl by
turning on the backlight full brighness. That will generate
a little more internal warmth.

Fogging is a common problem with Humminbird.

I had a temporary fogging problem on my Garmin the last time out - it had never happened before.
I store it with the cover on - so I have stopped that practice. I also put a small Silica Gel pack under the cover for a few days, hoping that would draw out any remaining moisture...
