Cleaning the Screen NOTICE Cleaners containing ammonia will harm the anti-reflective coating. The device is coated with a special anti-reflective coating which is very sensitive to waxes and abrasive cleaners. 1 Apply an eyeglass lens cleaner specified as safe for anti- reflective coatings to the cloth. 2 Gently wipe the screen with a soft, clean, lint-free cloth. Viewing Images on a Memory card You can view images that are saved on a memory card. You can view .jpg, .png, and .bmp files. 1 Insert a memory card with image files into the card slot. 2 Select Info > Image Viewer. 3 Select the folder containing the images. 4 Wait a few seconds for the thumbnail images to load. 5 Select an image. 6 Use the arrows to scroll through the images. 7 If necessary, select Menu > Start Slideshow. Screenshots You can capture a screenshot of any screen shown on your chartplotter as a .png file. You can transfer the screenshot to your computer. Capturing Screenshots 1 Insert a memory card into the card slot. 2 Select Settings > Preferences > Screenshot Capture > On. 3 Go to a screen you want to capture. 4 Hold Home for at least six seconds. Copying Screenshots to a Computer 1 Remove the memory card from the chartplotter, and insert it into a card reader that is attached to a computer. 2 From Windows Explorer, open the Garmin\scrn folder on the memory card. 3 Copy a .bmp file from the card and paste it to any location on the computer. Troubleshooting My device will not acquire GPS signals If the device is not acquiring satellite signals, there could be a 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 (Software Update, page 65). • If the device is using an internal GPS antenna, make sure the device has a clear view of the sky so 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 necessary, see the GPS antenna installation instructions for connection information and diagrams. • If the device is using an external GPS antenna connected using the NMEA 2000 network, select Settings > Communications > NMEA 2000 Setup > Device List. Make sure the antenna appears on this list. If it does not, verify the antenna installation and the NMEA 2000 network installation. • If the device has more than one GPS antenna source, select a different source (Selecting the GPS Source, page 3). 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. Check that the proper size fuse is installed. Refer to the label on the cable or the installation instructions for the exact fuse size needed. 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 ohm. • Check to make sure the device is receiving at least 12 V. To check the voltage, measure the female power and ground sockets of the power cable for DC voltage. If the voltage is less than 12 V, the device will not turn on. • If the device is receiving enough power but does not turn on, contact Garmin product 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. This is 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. 1 Find 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. 2 Select Settings > Preferences > Units. 3 Select the correct map datum and position format settings. 4 Create the waypoint again.
