All, Just installed a Kenwood DNX6140 head unit and KTC-200HR HD radio reciever. I can tune in to the regular local stations here and after a few seconds they switch to HD, the change in audio quality is noticeable. However, I am unable to tune to any of the HD-2 or HD-3 sub channels of any given frequency. For example 95.5 HD-1 works, but I am unable to tune to 95.5-2 HD-2 or 95.5-3 HD-3. What's the deal? I have read the manuals for the equipment front to back and cannot figure this out.

Anyone have any suggestions? I know that the KTC-200HR supports multicasting, so it should be able to tune to these stations. Thanks!
