If not, updatethe device software.• Make sure the device has a clear view of the sky so theantenna can receive the GPS signal. If it is mounted inside ofa cabin, it should be close to a window so it can receive theGPS signal.My device will not turn on or keeps turning offDevices erratically turning off or not turning on could indicate anissue with the power supplied to the device. Check these itemsto attempt to troubleshoot the cause of the power issue.• Make sure the power source is generating power.You can check this several ways.

Check that the proper size fuse isinstalled. Refer to the label on the cable or the installationinstructions for the exact fuse size needed. Check the fuse tomake sure there is still a connection inside of the fuse. Youcan test the fuse using a multimeter. If the fuse is good, themultimeter 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 groundsockets of the power cable for DC voltage. If the voltage isless 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 correctlocationYou can manually enter a waypoint location to transfer andshare data from one device to the next.
