I don't understand why but there is a fuse for "cigarette lighter" and a fuse for "12v Accessory socket" in the interior fuse box of the 380. In my sons 380 there is only one 12 volt socket below the radio which I presumed would be considered the cigarette lighter. It stopped working. I checked the fuse for the cigarette lighter and it was fine and figured it must be something else in the circuit. Turns out the fuse labeled "12v Accessory" was blown. I didn't realise there was a fuse for 12v accessory until I looked in the owners manual. The symbol on the interior fuse box cover is a semi-circle with a staight single line from the back of the semi-circle and two straight lines coming from the front of the diameter line of the semi-circle kind of like -(|= more or less. Look it up in your owners manual. I do have a 2007 380 with two 12v sockets, one below the stereo and one in the centre console. The one in the centre console isn't switched and always has power even when the car is off. I think this was a factory option. I figured someone else who finds this thread trying to fix the same issue might find the info useful.
