Love the sound quality of my new truck, but need to dial up the lows summore, and want to dial out the 6Khz range to take some of the harshness of some of the albums I listen to. Can SYNC give us any kind of graphic or parametric EQ?

 

No, there is no eq updates that I know of. If you have a center channel speaker in the top of your dash, unplug it. Unplugging the center speaker greatly improves sound quality.
