Unconnected wires behind

[Reggie-rock]

At last removed my Command Sat Nav head unit from my 2006 CLK 350 convertible for repair, but found two wires going to this small connector behind the unit (pictured in my fingers) which was not plugged in anywhere, and seemed to be wound round other wires to keep it out of the way.
Does anyone know what this is for and connects too?
Many thanks.
