Anytime I change the radio station it changes back to the rock equalizer setting, which cranks the bass way up and turns the treble down to half, this makes it very annoying anytime I want to change a radio station because I have to readjust it every time or it sounds terrible. Is there any way to make it just stay on the custom equalizer settings when it changes instead of resetting every time to the rock equalizer? Thanks for your help.
