Im going insane! My shaker500 cd player makes a chirping noise lately. I installed this myself last summer so I could have a cd changer and it has worked fine for me, but the past week or so I have noticed a chirping sound coming from the unit itself (not the speakers). It doesn't matter which cd it's on or if the volume is loud or completely mute - it still just chirps away, it's very faint so noone else really hears it unless I say something about it, but once I started hearing it I can't stop it drives me insane lol... Anyone know what this is or how I can fix it? Today I even did some palm-to-front-of-shaker action and that made the chirping a little louder (momentarely then it quieted back down). Someone help me!
