I live about 35 miles southwest of Chicago. I receive all the area FM radio stations clearly. However, I've noticed the HD radio tuner isn't very sensitive. It works fine when I'm driving in an area with open fields around, but in normal suburban driving the HD tuner keeps cutting in and out. So much so that it makes the option pretty useless for me. Especially if I select HD2 or HD3 stations. It will cut out and I won't have anything playing until it picks up an HD signal again. Being fairly close to the Chicago radio market and not having any problem picking up regular FM signals, I figured there wouldn't be any problem listening to HD radio, but this just hasn't been the case. Anyone else having a similar problem with the sensitivity of the HD tuner?
