Hi! I recently acquired my first car - a lovely nissan micra k11 celebration! I know pretty much nothing about cars, ordering my provisional soon so haven't had any lessons yet. My silly question: Most of the controls are covered in the manual, however there is a wire behind the steering wheel, coming from the right-hand side of the dashboard, and I really want to know what it's for? I'm guessing it was added by a previous owner, but the last driver never knew what it was for. The bit that plugs into something is cylindrical and I'm wondering if it's to plug a phone in but it looks a bit too big - have yet to try it, have been short on time lately. Maybe to plug in a sat nav or something? Literally have no idea, feel free to laugh at my clueless terminology
