Yep! That was what I was talking about...the "user" settings. These settings make a HUGE difference in how the radio sounds, and I haven't ever seen an explanation in the manual as to exactly what these are for or what they actually do. All I know is I fooled around with it and there was no bass. But it has since returned. You know, making a car stereo that isn't an ordeal to the owner should be pretty easy. They should be a stupid and easy to control as possible, and this one, as bare bones as it is, isn't so. Glad I could be of assistance. Now that you have it set, never fiddle with it again, I know I haven't!
