Apparently there is no way to set the clock in a B5 S4, as it does not get the clock info from the instrument cluster. This is odd as everything displays on the DIS perfectly so one would think the clock info would make it over as well. It could be that the clock info is not transmitted on the CAN on the B5, just as the speed signal is not transmitted. Also, the offset from GPS is disabled, so there is no way to set the clock. Is there a way to disable the instrument cluster so that one can use GPS momentarily to set the clock and then switch back?
