How do I work this?

I had planned on changing the subject for my next post, but I just saw this. Well said, and it ties in with my aforementioned interest in maps.

My two cents on GPS navigation for your car can be summed up in six words, don't throw out your paper maps. These GPS units are fun gadgets, and are great at what they do - giving turn by turn instructions while you're under way. Just don't throw out your common sense, and understand they have limitations. You'll never see the "big picture" with one of these. For instance, if you want to plan a vacation, including side trips...get a map.
