Troubleshooting
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 Vdc.
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 Vdc, the device will not turn on.
• If the device is receiving enough power but does not turn on, contact Garmin product support.
