Had the same problem with mine...constantly fading in and out, losing the signal, reloading. Moved the antenna to the top of the radio, thinking it would have a better shot through that part of the fairing, as it's pretty much a clean uninterupted plane of material. No difference. Finally took the bracket out of the fairing as all it was doing was taking up space, unstuck the antenna from the top of the radio, cleaned off a place right on top center of the leather dash, and stuck it down, protecting the wire between the inner/outer fairing with a little cushion of foam tape.
Works perfectly now...the only time I lose a signal is an extended overpass, or really, really thick forest hanging over the road and I'm down in a valley. That's where mine will stay...listen to it all the time now.
