is it the full speed connect (blue squarish end) or the usb? what type of ipod do you have? also if its a touch what iSO is installed?
my old 9886 was hooked up through the full speed connect and after i installed iSO4 it was so horribly slow loading artist names and album names. i literally had to spin the volume nob for 10 minutes to get to the G's. so if thats the problem get yourself the kenwood that i have. its sexy, charges your ipod at the same time, and doesn't have that problem.
