Hi all I just noticed today, that when I played music over USB the SYNC voice was stuttering/breaking up and also the music as well. I'm using the basic SYNC that came with my Fusion no NAV. I have v1.3 installed since 2010 and I have checked and there is no other updates available for my Fusion since 2011. Everything for the past 7 yrs was working fine with SYNC until now. Would a SYNC factory help? Or should I just take the positive battery terminal off for 10mins? Thanks.
