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.
• Make sure the device has a clear view of the sky so the
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.

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 is at least 10 V,
but 12 V is recommended.
To check the voltage, measure the female power and ground
sockets of the power cable for DC voltage. If the voltage is
less than 10 V, the device will not turn on.
• If the device is receiving enough power but does not turn on,
contact Garmin product support at support.garmin.com.

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.
