Confused about the complex array of marine navigation software for your Garmin Marine GPS? You are not alone. Here we will take a look at how to find the right charts and what format to purchase to ensure it is compatible with your marine GPS.

BlueChart g2 Vision is highly detailed, visual representation of above and below water with 3 dimensional perspective. High resolution satellite imagery is standard with most Garmin chart plotters. When you upgrade with the optional regional maps you also get aerial photography that provides unparalleled detail for navigation using realistic visual representations. BlueChart g2 charts install in your GPS using the SD card slot on the device to provide complete marine coverage.

The 3-D mapping capability allows you switch between topside view and fish eye view for a realistic picture above or below the water. Below the surface views include shaded depth contours and other features such as reefs, rocks, and shoals. Optional auto guidance software charts the safest known route automatically avoiding known obstacles such as buoys, reefs, harbors and so on. You can also get information about fishing charts, tides, currents, wrecks, anchorages and other points of interest.
