Ford Motor Co. says it will be the first automaker to offer iTunes tagging capability in a factory-installed HD Radio receiver. The feature will be launched in late summer on select models and will rely on iBiquity Digital Corp.'s HD Radio technology. A driver will be able to tag a song with the push of a button on the HD Radio display. Doing so will store the song's metadata (not the song itself) in the radio's memory. Up to 100 tags can be stored via Ford Sync technology. The metadata can later be downloaded to an iPod, which when synced to iTunes is displayed as a song list. Users can preview the songs and select which to purchase. HD Radio receives digital signals and plays them with much better sound quality than conventional radios, Ford says. HD Radio-enabled receivers also will provide Program Service Data, a feature that allows information such as song title and artist name to appear on the screen. Ford currently offers HD Radio on its Volvo models only. The company will announce on Jan. 7 at the Consumer Electronics Show on which specific models HD Radio and song tagging will be offered.
