So is the "Premium" SYNC/Navigation sound system in these garbage, or have I just not figured out how to adjust it? I can set it to driver's seat, adjust fade, balance, bass, and treble, but the sound quality is horrible. People talking sounds like it's echoing from a tunnel, and music is missing most of its mid-tones and a lot of the sharp highs, almost like there's a "concert" setting you can't turn off. I see the equalizer, but can you adjust frequencies and ranges?
