German magazine FOCUS broke a story (or rumor) that Apple and Mercedes are planning to fashion select 2009 model vehicles with combo Personal Media-GPS navigation units. Will the duo outfit an iPhone dock to wirelessly connect with other in-vehicle A/V systems for both entertainment and in-dash navigation, or will a dedicated PND strategy prevail over a converged and networked approach? Who knows, but I imagine user-machine interactions at 130 km/h on the Autobahn might influence design towards more intuitive voice-driven form factors around larger car-spaces versus device-space.
