How to Use TOPO Maps on a Nuvi 680

A topographic map shows more details than an ordinary map. You can see details of the landscape and physical space of the land, such as elevation. Topographic maps are definitely more detailed and useful for people who will be traveling on foot. If you own a Garmin Nuvi 680 GPS device, then you can use topographic, or TOPO, maps with your device while navigating trails and other outdoor areas.
