Thank you very much for the feedback. It's good to have a heads up about the learning curve. I'd rather be aware of it now than once I get the GPS home.
Having never worked with or used a GPS in person, I have a few naive questions...Would not all units have a compass(not just high end ones)? That seems like it would be a pretty basic feature. Also, should i be purchasing any additions to go with the GPS? Maps? Memory cards? I've been reading about people needing to buy maps. Does it depend on which GPS you buy?
