One of the reasons that I have been discouraged to purchase a color screened GPS unit is, the experience that I had going from the old black lcd screen cel-phones to the color phones. The color phones have way cooler features, but get them out in direct sunlight, and the screens visibility drops to near zero. If I did my Geocaching at night, this would be no problem, but my caching is during the day. I have never used a color gps unit, nor have seen one in operation. Are there similar problems in the field with the new color GPS units verses the old black lcd screened units?
