I don't really have an opinion about screen size but it would seem logical
to get the largest size that you're comfortable with and will fit on or in
your console. My recent experience with screen wash-out in bright sunlight,
though, has been just the opposite as that of your dealer. That may have
been true with some of the older units but not any more. I recently
replaced an older grayscale LMS-160 Map with a color LMS-330c and
discovered, to my amazement, that viewing even in direct sunlight was
excellent and was much better with the new unit than with my old one. I'm
so impressed with it that I'm considering a new color sonar unit for the
front deck.

It's not my money but I'd say get what you want!

I want to buy a GPS and am strongly considering the new Lowrance GlobalMap
3500c [color]. My dealer is willing to order it for me BUT he strongly
suggests I would be much happier with a Lowrance 4000M [greyscale]. He
said
his experience with color is that is washes out in the sunlight. Also the
4000M has a much larger screen than the 3500c. Please share your
thoughts.
