The GPS allows me to see the layout of unfamiliar roads I'm on. I can see what curves are coming up, and where intersections are. That's very useful when driving winding mountain roads, especially at night. I can also at a glance see alternative routes. Often I display nearby landmarks and decide on the fly which ones to visit. Other useful-to-me features are the speed warning feature, traffic alerts, and trip data. I also can turn on the backup camera for a better rear view. I do use the GPS to take me to unfamiliar addresses but I don't use it for city-to-city navigation. I prefer a small dash-mounted GPS unit over an integrated screen because I can place the device where I can easily see it without taking my eyes completely off the road. I had a Gamin that looked like an alarm clock back in the late '90s. How do you use your GPS?
