Quick look at the D3 Fridge / Coolbox

Wow yes, those B&O ones are bigger.
While you are in there, do you see a mechanism comprising or a 90˚ gear with cross-cut nylon teeth about 1" dia.
It looks like you wind it with a hex tool and it drives a verticle shaft which disappears down behind everything.
It is between the rear light and navi/radio/tv/amp assembly.
I saw this on mine and wondered what it is for.
I turned it a few times, but nothing happened.
