Actually it has been flaky for a few years now. When I turn the volume up or down sometimes it jumps all over the place, getting louder when I wanna go soft and vice versa. If I am persistent it will do what I want but it takes a little while longer.

Well, I've always been i na older junky car so no biggie but now I might get something nice so if I can manage to get the empeg in the new car I'd like it to operate well.

Any idea how to fix?
