Getting Started
Initial Chartplotter Settings
The first time you turn on the chartplotter, you must configure a series of initial settings. You must also 
configure these settings when restoring original factory settings (page 86). You can update each of these 
settings later. Follow the on-screen directions to configure the initial settings.
GPS Satellite Signal Acquisition
When you turn on the chartplotter, the GPS receiver must collect satellite data and establish the current 
location. When the chartplotter acquires satellite signals, the signal strength bars at the top of the Home screen 
are green 
. When the chartplotter loses satellite signals, the green bars disappear  and a flashing 
question mark appears on the vehicle (boat) icon on the chart screen.
For more information about GPS, go to  www.garmin.com/aboutGPS.

reference photos of ports, harbors, marinas, and other points of interest. You can insert blank SD memory cards 
to transfer data such as waypoints, routes, and tracks to another compatible Garmin chartplotter or a computer 
(page 52). The SD card slot is located on the front of the chartplotter.

Other features common to most charts include depth contour lines (with deep water represented in white), 
intertidal zones, spot soundings (as depicted on the original paper chart), navigational aids and symbols, 
obstructions, and cable areas.
Navigating to a Point on the Chart
 CAUTION
The Auto Guidance feature of the BlueChart g2 Vision data card is based on electronic chart information. That 
data does not ensure obstacle and bottom clearance. Carefully compare the course to all visual sightings and 
avoid any land, shallow water, or other obstacles that may be in your path.
When using Go To, a direct course and a corrected course may pass over land or shallow water. Use visual 
sightings and steer to avoid land, shallow water, and other dangerous objects.
NoTe: The Fishing chart is available if you use a BlueChart g2  Vision SD card or a BlueChart g2 SD card, or 
if your built-in map supports Fishing charts.

6.  Review the course indicated by the magenta line.
NoTe: When using Auto Guidance, a gray segment within any part of the magenta line indicates that Auto 
Guidance cannot calculate part of the Auto Guidance line. This is due to the settings for minimum safe 
water depth and minimum safe obstacle height ( page 46).
7.  Follow the magenta line, steering to avoid land, shallow water, and other obstacles.
Panning the Navigation Chart, Fishing  Chart, or Radar Overlay
You can pan away from your present location and to other areas on the Navigation chart, the Fishing chart, or 
the Radar Overlay.

or if your built-in map supports Fishing charts. The radar overlay is available when connected to a compatible 
radar.
1.  From the Home screen, select  Charts.
2.  Select  Navigation Chart, Fishing Chart, or Radar overlay .
3.  Touch and drag the Navigation screen to pan the map.
