"HD Radio not high definition: Investigation by Keefe Bartels"
"Automakers are aware of the complaints associated with HD Radio. For example, in 2007, BMW released a Service Information Bulletin describing the problems associated with HD Radio, but noted that there was no retrofit kit or procedure available. The attorneys at Keefe Bartels are continuing their investigation into HD Radio and whether consumers are being forced to purchase technology that does not work as claimed. If you have experienced problems with your factory-installed HD radio receiver, we are interested in speaking to you."
