  If your Garmin GPS device isn't turning on or keeps turning off, first, ensure the power source is working by checking if other devices connected to it are functioning. Then, inspect the fuse in the power cable, located in the red wire's holder, and confirm it's the correct size according to the cable label or installation instructions. Use a multimeter to check the fuse; a good fuse reads 0 ohm. Also, verify the device receives at least 10V, preferably 12V, by measuring the voltage at the power cable's female power and ground sockets. If the voltage is below 10V, the device won't power on.

If necessary, create the waypoint again.

If using an external GPS antenna, verify it's properly connected to the chartplotter or NMEA network, consulting the antenna installation instructions for connection details if needed. For an external GPS antenna connected via the NMEA 2000 network, go to Settings > Communications > NMEA 2000 Setup > Device List to confirm the antenna appears. If not, check the antenna and NMEA 2000 network installation. If multiple GPS antenna sourc...
