It only works when something is plugged in? If so, that's how it supposed to work, unless you can give further details as to what else is happening.

Please confirm the powered device is not also the Aux input device. If so, try a different input device into Aux port. Tablet or something...

If some control board for the AUX input lost power, it could be that feedback through another circuit (Accessory +12), makes a connection that wouldn't be there when the port is empty.

Check all the fuses under the dash (both kick panels) and under the hood. The owners manual provides a brief description of what some do. I suspect it's 10A or less.

Do you mean that it will only work if the playback device is getting power from the cigarette lighter supply?
