Using BlueChart g2 Vision
Optional BlueChart g2 Vision preprogrammed SD cards allow you to get the most out of your
chartplotter. In addition to detailed marine charting, BlueChart g2 Vision has the following features:
Mariner’s Eye 3D
—provides a view from above and behind the boat for a three-dimensional
navigation aid. The BlueChart g2 Vision Mariner’s Eye 3D is more detailed than the preloaded
data.
Fish Eye 3D
—provides an underwater, three-dimensional view that visually represents the
sea floor according to the information on the chart.
Fishing Charts
—displays the chart with enhanced bottom contours and without navigational
data. This chart works well for offshore deep-sea fishing.
High Resolution Satellite Imagery
—provides high resolution satellite images for a realistic
view of the land and water on the Navigation chart.
Aerial Photos
—displays marinas and other navigationally significant aerial photos to help you
visualize your surroundings.
Detailed Roads and POI data
—displays roads, restaurants, and other points of interest (POIs)
along the shore.
Auto Guidance
—uses specified boat safe depth and chart data to determine the best course to
your destination.
Using the SD card
You can insert or remove a BlueChart g2 Vision SD card while your Garmin GPS unit is on or off.
To insert the SD card, open the access door and press the SD card in until it clicks. Press in again to
eject the SD card.
