their seems to be alot of radio problems with the harley unit and would'nt you know i have a problem with mine as well. i have an 07 ultra and the rear headphones are contantly cracken and making static. we have switched headphones, cables, and have plugged the cords into both connectors and i cannot duplicate the problem from the front position. the front is fine but no matter what we do the rear messes up. the headphones are the originals and the radio is stock. my girl friend at times has a problem hearing all modes because of static. it doesn't matter if its the cb, cd, or radio. anybody else with this problem? like i said the front position is as clear as a bell. help!!
