Marine Database
The GPS 48 contains an updateable, marine database
that displays city locations and nautical navaids on the
moving map. Check the Garmin website for possible
nautical navaid updates.
City locations are depicted by a small square icon,
cities are displayed at the zoom scale specified on the city
setup menu (see page 26).
The nautical navaids contained in the GPS 48 marine
database include racons, radio beacons, fog horns, day-
beacons (red triangles, green squares and white dia-
monds), lit and unlit navaids. Each navaid is represented
