I have owned many GPS units and of the latest are the Magellan SporTrak Map, Meridian Gold, Meridian Color and Garmin 60CS. Out of these units the Garmin GPSmap 60CS is a phenomenal piece of equipment. The 60CS hasn't, for the most part, come up with anything new, but has fine tuned and polished what makes an all round GPS unit extremely dependable and exciting to own. Memory may not be infinite, but 56mb is quite substantialby any means. The Magellans are very difficult to read in the sunlight needing the assistance of the backlight . . . which drains the battery. The 60CS is beautiful in or out of the sunlight. The screen on the 60CS has a daytime, nightime mode which automatically switches according to the sunrise and sunset information. It is truely a thing of beauty. When I have to depend on the accuracy of what I see on my GPS screen, the Magellans have failed in that aspect. I still have the Magellans, but I have taken the batteries out of them for storage purposes. The Garmin GPSmap 60CS is working overtime. I depend on my GPS unit to do it's job . . . and do it well, my life or the lives of others may depend on it someday.I feel secure with the Garmin 60CS. Buy the 60CS, try it out for 29 days and keep your receipt. You'll see what I mean.
