This is my first post on the forum since owning my second Fusion, a 2010 Sport with Moon and Tune as the only option. With the dizzying array of audio possibilities the system offers I haven't listened to the radio very much. However, I noticed that while listening to FM stereo on a local station the sound goes from muffled bass with no treble to a great full sound, constantly fading in and out even while sitting still. Has anyone else experienced this issue? It is quite annoying. Love my Sport otherwise!! Loved my '06 SE I-4 5spd as well!
