VX Power Supply - No Power?

[Scruba]

Hi all. Plugged the GPS into the Power Supply outlet and it has no power.
Where do I start to look to troubleshoot this?

Cheers,

First check the fuse and if that is ok, check the wiring at the back of the power socket. There is a big nut that holds the socket in and that often becomes loose.

Sorted thanks. I had the dash out checking the HVAC so fiddled with the socket. Turned out to be the fuse!
