Which GPS for Business Travel?

Gone are the days of looking at maps (that may or may not have been right side up) while I careen down the highway, trying to get to a meeting on time. GPS has made the navigation part of my days much easier - not to mention safer - and I can’t imagine doing my job without my trusty Garmin. Our biggest problem as business travelers today is figuring out which GPS is best for our travel needs. To help you decide, I have compiled a list of GPS features to look for, based on your most frequent mode of business travel.
