Digital SwitchingYour chartplotter can be used to monitor or control circuits when a compatible system is connected.
For example, you can control the interior lights and navigation lights on the vessel. You can also monitor live well circuits.
To access the digital switching controls, select Info > Circuit Control.
For more information about purchasing and configuring a digital switching system, contact your Garmin dealer.
Rotating the GRID JoystickFor certain installation situations, you can rotate the orientation of the GRID joystick.

You can capture a screenshot of any screen shown on your chartplotter as a bitmap (.bmp) file. You can transfer the screenshot to your computer.
Capturing Screenshots
1Insert a memory card into the card slot.
2Select Settings > Preferences > Screenshot Capture > On.
3Go to a screen you want to capture.
4 Hold Home for at least six seconds.
Copying Screenshots to a Computer
1Remove the memory card from the chartplotter, and insert it into a card reader that is attached to a computer.
2From Windows® Explorer, open the Garmin\scrn folder on the memory card.
3Copy a .bmp file from the card and paste it to any location on the computer.
TroubleshootingMy device will not acquire GPS signals
If the device is not acquiring satellite signals, there could be few causes. If the device has moved a large distance since the last time it has acquired satellites or has been turned off for longer than a few weeks or months, the device may not be able to acquire the satellites correctly.
•Ensure the device is using the latest software. If not, update the device software (Updating the Device Software).
•If the device is using an internal GPS antenna, make sure the device has a clear view of the sky so that the internal antenna can receive the GPS signal. If it is mounted inside of a cabin, it should be close to a window so it can receive the
GPS signal. If the device is mounted inside a cabin and cannot be placed in a location where the device can acquire satellites, use an external GPS antenna.
•If the device is using an external GPS antenna, make sure the antenna is connected to the chartplotter or the NMEA network.
•If the device has more than one GPS antenna source, select a different source (Selecting the GPS Source).
My device will not turn on or keeps turning off
Devices erratically turning off or not turning on could indicate an issue with the power supplied to the device. Check these items to attempt to troubleshoot the cause of the power issue.
•Make sure the power source is generating power.
You can check this several ways. For example, you can check whether other devices powered by the source are functioning.
•Check the fuse in the power cable.
The fuse should be located in a holder that is part of the red wire of the power cable. A 3 Amp fuse is used in this power cable. Check the fuse to make sure there is still a connection inside of the fuse. You can test the fuse using a multimeter. If the fuse is good, the multimeter reads 0 ohms.
•Check to make sure the device is receiving is at least 10 volts, but 12 volts is recommended.
To check the voltage, measure the female sockets 8 (power) and 2 (ground) of the power cable for DC voltage. If the voltage is less than 10 volts, the device will not turn on.
•If the device is receiving enough power but does not turn on, contact Garmin product support at www.garmin.com/support.
My device is not creating waypoints in the correct location
You can manually enter a waypoint location to transfer and share data from one device to the next. If you have manually entered a waypoint using coordinates, and the location of the point does not appear where the point should be, the map datum and position format of the device may not match the map datum and position format originally used to mark the waypoint.
Position format is the way in which the GPS receiver's position appears on the screen. Commonly displayed as latitude/ longitude in degrees and minutes, with options for degrees, minutes and second, degrees only, or one of several grid formats.
Map datum is a math model which depicts a part of the surface of the earth. Latitude and longitude lines on a paper map are referenced to a specific map datum.
1Find out which map datum and position format was used when the original waypoint was created.
If the original waypoint was taken from a map, there should be a legend on the map that lists the map datum and position format used to create that map. Most often this is found near the map key.
2On the chartplotter, select Settings > Preferences > Units.
3 Select the correct map datum and position format settings. 4 Create the waypoint again.
