Plan your route before you get on the road.
Well, sure, you can always use common sense, right? What fun is that?
But then, the Garmin provides more than just the map function.
It allows you to find destinations like restaurants, stores, airports, etc quite easily in unfamiliar areas. For example, you can locate, say, the nearest mexican restaurant or type in the name of a business. There are the Bluetooth functions for those that can use them.
One thing I like is the ability to calculate my predicted time of arrival at a destination.
Of course you can get along with a map. Some of my best friends use maps.
I happen to like gadgets, and the Garmin is a gadget
