Okay, so it's probably not a cigarette lighter any more? On my VW MkV the lighter socket was always on. If I plugged something in to it then it stayed powered up even when the ignition was off. The Mark VI doesn't do this. When one turns the ignition off then the socket is powered off. I would like to keep it powered on, if only to maintain the charge in my navigation thingy.
Does anyone know if this setting can be changed?
