Scion has selected iBiquity Digital to provide HD Radio technology in some of its audio systems. Scion hasn't said how it plans to integrate iBiquity into Scions, or which cars will get the systems first, but the partnership marks another incursion of HD Radio into the mass market -- BMW, Ford and Jaguar already offer it, with Volvo opening the HD spigot next year. HD Radio offers stations the ability to transmit multiple programs over a single FM frequency with crystal clear reception -- and there are more than 1,600 stations across the nation, available to 83-percent of the country. In the future, HD plans to introduce features that will match or better those offered by satellite radio. But unlike satellite radio, HD is free.
