For you who like your Road Atlas or smartphone, you should know that a GPS can almost effortlessly guide you to the nearest hospital, ethnic and other restaurants of your choice including BBQ, German, Chinese, American, Bagel or Donut, British, Diner, French, Deli or Bakery, Italian. Mexican, Pizza, Seafood, Steak, or gas station, freeway rest stop, city hall, fire department, library, courthouse, police station, post office, school, bank, parking, entertainment, attractions, auto services, lodging, shopping and airport.
Finding a hospital quickly could be important one day.
A GPS makes travel much more relaxing as it is so easy to find what you need as a traveler.
Not all of the others can do it but a Garmin can be used to find a coordinate type address that is used in some parts of the country. An example is W100N5000 Main Street.
A GPS is not perfect but works for us without error about 99.5% of the time.
We have a Garmin Nuvi with a 5" diagonal screen. I want neither a larger nor a smaller screen next time; 5" is just right. Its antenna is so sensitive that it can read the satellites from inside of our house.
We don’t worry about updates; just buy new every few years. GPS prices have come down.
