iBiquity, the developer and licenser of HD Radio Technology, introduced Gigaware Navigation Control HD Radio Receiver accessory and the HD Radio application. The accessory/app combination enables iPhone and iPod Touch to tune into HD Radio broadcasts. Adding HD Radio Technology to the iPhone and iPod touch (compatible with models updated with 3.0 software) is a two-step process: 1) Buy the Gigaware HD Radio accessory, designed for and sold exclusively at RadioShack for an MSRP of $79.99, 2 ) download and install the free application from the App Store (under the Music category). The app enables you to preview content currently airing and directly select a main station or multicast channel stream, in addition to bookmark your favorite stations and multicast channels. An iTunes Tagging button on the Gigaware navigation accessory also allows to “tag” songs for future review and purchase via iTunes. It gives you access to more than 2,000 HD Radio stations on the air, and 1,000+ new FM multicast channels (HD2/HD3).
