Redone, When I was looking, it seemed that some were designed for street navigation-great road maps and turn by turn instructions, not what I wanted. Some were designed to be a hand held navigation device, what I wanted. I selected a Garmin 60CSx, it does everything I need it to do. Highway map reading, turn by turn instructions, it is also great for overland navigation. I have a mount in my boat, works great on the water in remote areas of northern MN. I flip it on now and then when flying commercial-it;s kind of fun to monitor real time navigation info at 40,000 feet and 560 MPH. I have ice fishing honey holes, agate picking hot spots and street addresses saved in memory, works great for me. My wife hates it, she bought a Nuvi, but she just wants to get from here to there in the car. What ever works for you.
