I have a amp and new speakers in the fairing, and rear speakers in the lids. It has never sounded right on the hwy. I finally had a friend take it in for a flash, and it sounds killer now, even on the hwy. The fader, and all the setting show up now. I'm not sure which flash he did, but it fixed the avc issues.
