The advantage is clear - whether you're in deep woods or just near tall buildings and trees, you can count on GPSMAP 78 to help you find your way when you need it the most.

Add Maps

Adding more maps is easy with Garmin's wide array of detailed marine, topographic and road maps, available on microSD card. Conveniently plug in BlueChart® g2 preloaded cards for a great day on the water or City Navigator NT® map data for turn-by-turn routing on roads (see maps tab for compatible maps). The card slot is located inside the waterproof battery compartment, so you don't have to worry about getting it wet. GPSMAP 78 also supports BirdsEyeT Satellite Imagery (subscription required), that lets you download satellite images to your device and integrate them with your maps. In addition, the 78 is compatible with Custom Maps, free software that transforms paper and electronic maps into downloadable maps for your device.
