You seem to be the person to ask my questions. I own a Magellan Meridian Gold and have used it for 7 years. I think I know just about everything about it. I use it in my pickup truck on cross country trips. I have it attached to my laptop which is on a stand on the front seat. The Meridian interfaces with the computer serial port and I can follow my progress and position in real time on the computer screen map (Topo 3d).
I want to buy another GPS. If I could I would buy another brand but I am told that the only brand that interfaces with a computer in real time is the Magellan products.

Therefore, I am looking at the Explorist series. I don't want cameras and bells and whistles. I would like a GPS that puts more on the computer screen than just a triangle showing my position, like speed, time, direction, distance. I have to read those on the actual handheld GPS on the dash. Anyway, I want to upgrade to a "non-legacy" yet, model that can be used the same way as the Meridian.

I also want to take it with me on a trip to South America. So I need to load the World Base Map. I am told that the old World Base Map, which I bought years ago, is not as good as the current one. In South America I will use it only as a handheld.

What GPS would you suggest that I buy. What about the Explorist 310 or 500 series. Any advice would be welcome. Thanks
