It is so important to have a GPS device to reach your destination. Even if you’ve been there before, this device is recommended if the drive is long. Else, you can use it once you reach halfway. For new trips, GPS is a must. Feed the location into the system and have it guide you. In the beginning, it may also show you two or three different routes to get there so that you can pick the best one accordingly. Not just the route, it also helps you find the shortest route, the route with lesser traffic, and much more information depending on the settings. So, yes, it is important to have one while you are on a trip.
