I installed my Garmin 176C on a nice bracket that has the ability to swing every which way. Its anchored just inside the companionway hatchboards and it swings inside when closing up for the day and out when sailing. This was a Bill Goldsmith suggestion and it works well. The only problem I see is that there is a helluva glare on the screen that makes seeing the information difficult at times. I suppose I could fashion a hood over the unit but I know I'm not the first chap to experience this problem. Anyone have a sure fire method for getting rid of glare? I remember putting some sort of screen over my computer monitor when glare occured from light coming in a window. I don't know if it was a polarizing screen or what. I think something like that would work better than a shade or hood. Any ideas?

Re: Garmin 176C and Glare
Warren,
Some, if not all, LCD screens are polarized. If you were wearing polarized glasses, you may be experiencing nearly total blocking of the image and not a reflection.
On the other hand, my Rx sunglasses do not seem to negatively affect my B&G Network display unless I tilt my head, so the B&G must be polarized close to the same as my glasses, which would be vertically if I understand the physics at all.
Maybe a polarizing filter on top of the display would help. You ought to be able to check it out with a cheap lens from polarized sunglasses.
Good luck!

Re: Garmin 176C and Glare
Warren,
I had the same experience with my 176C, although I installed it late inthe season and didn't have alot of time to play with it. My first impression is that it is not an "anti-glare" screen. I would also beinterestd if there are any overlays available, perhaps made for laptops, that could be modified for the unit. What I have done is generally NOT rely on the chartplotter screen while underway in daylight. Even when not drowned out by glare, it's kinda small to be seen from the back of the cockpit from its mounting place in the companionway. Rather, I use the chartplotter to set up a route, and then page to the large numbers display for steering. I found that when it glares, I tilt it up a bit, the screen is still visible and the glare is reduced, and you can see the large numbers.
I figure everything's a tradeoff. GArmin makes a large screen chartplotter with anti-glare, but it's too big for my tastes on a 27. Also, I heard somewhere that the 176 gray scale version is better regarding glare, but you do not get those cool color maps.
Any progress on locating anti-glare overlay?
