The Problem May Not Be The Vehicle
The first diagnostic step is gaining a better understanding of your problem. All you know so far is that when you plug in your phone/Nav/camera/whatever, "it doesn't work".
The Problem May Not Be Power To The Socket
If you've determined that your device doesn't charge in one particular socket but does charge in other sockets, either in the same car or a different car, we still have not conclusively found the problem. With the ignition key off, take a look inside the socket itself for any obvious blockage or damage.
Always Check The Fuses Next
We've said this so often, yet it always bears repeating: before presuming that any device is broken, check the car's fuses. For starters, get your hands on the car's owner's manual which will tell you the location of the fuse boxes.
Replacing The Power Socket
If the fuses check out ok yet the socket still does not work there is still some remote chance that there is an open circuit between the fuse and the socket. Tracing and repairing such a wiring fault is beyond the scope of this article.
