Summary: The Garmin Colorado 400c: I use the unit as a heart monitor, on my bicycle, and on the water for navigation. It fits my usage quite nicely. It can be seen in sunlight. Its only real negative is the back lighting is not very bright. I agree with others who have noted the previous lighting issue.
Summary: I have owned the Colorado 400C for 2.5 months and use it on a sailboat going less than 8 mph. The 2 problems are 1) the speed jumps all over the place second by second when going that slow so it is useless for sailing needs (I wonder if the ETA, ...
Summary: I just returned from a 150-mile sail on the Maine coast using the 400c as our primary navigation tool.

I still recommend the unit if you are willing to put up with this issue. Again, I haven't been able to find an option.
Summary: Overall, I'm quite happy with the unit. Updating to software version 3.20, GPS software version 2.90 has addressed some of the issues mentioned earlier. However, there are some issues with this latest rev with displaying maps properly under multiple profiles.

Excerpt: Definitely the best GPS device I have owned out of several over the years. I am a sea kayaker, so device comes with me every time I paddle (several times a week year around).
