Following in the footsteps of BMW, Mercedes-Benz announced it will offer HD radio in some of its 2009 models. HD radio is a digital broadcast that offers CD-quality sound for FM stations. BMW has been offering it on its models for the past year, and now Mercedes-Benz will include it as an option on the 2009 E-, M-, R-, GL-, and G-class, all but the E-class being SUVs.
Most radio stations in major cities have an HD broadcast now. There are approximately 40 stations in San Francisco alone. Because the format requires less bandwidth, many stations have multiple HD channels.
