Scion announced that it will offer iBiquity Digital's HD Radio technology in select audio systems in the near future. The company is being vague about the particulars—you know, things like which cars it will be in, how much it will cost, and when it will be available. But this is still significant, because HD radio has one huge advantage over satellite radio: It's free.

According to Toyota, there are more than 1,600 digital HD Radio stations in the U.S. today. Broadcasts are available to 83 percent of the country's population. Some manufacturers already offer HD radio, such as Ford and BMW, and car owners willing to install aftermarket receivers can choose from a wide variety of head units. But HD radio isn't a panacea; unlike satellite radio, HD stations don't cover the entire country and don't offer the same wide selection.
