For 2003, BMW will finally offer a DVD-based navigation system -- meaning that you won't have to give up an in-dash CD player if you opt for the nav system. Other changes include a standard front armrest for all 325 models, as well as a rear center headrest for all sedans and wagons. Additionally, all wagons will come with a moonroof. In terms of options, the Premium Package for all 325s now includes automatic headlights and rain-sensing wipers, and the Sport Package for the 330xi includes double-spoke alloy wheels and run-flat tires.
