Summary: I just returned from a 150-mile sail on the Maine coast using the 400c as our primary navigation tool. I installed the marine mount on the cabin top under the dodger and hard-wired it into the boat's 12v system using the accessory cord, which doubles the brightness compared to battery power, so it...
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.

Summary: A must for every yachtsman. Simple single handed operation, large bright screen and packed full of features. Garmin has produced a serious instrument at a reasonable cost. That said, nothing is perfect and the one thing the engineers left out was the ability to connect it to a DC power supply.
Summary: I have a full-size chart plotter and radar on my 41 foot ketch. The 400c is a backup unit that is handy to use to check distances and points of interest without changing the displays on the full-size unit.
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: Having 15 years of using Garmin products, they clearly missed the mark with this one. The screen is useless when attempting to use outside in the sunlight. As a marine oriented unit I find this an amazing product development oversight.
