If its the same as mine its just 2 screws, if you look just above the clocks there's a little arch shaped mound 2 screws in there, take them out and the clocks just pull forward then its one plug in the back of the unit, try that or re-set the ecu if that don't work, don't know how to do that with the fuses on BMW but if you disconnect the battery for a couple of mins that should re-set it.
