I've searched and found tons of issues on the CDR23. But none of them described the issue that I have. Seems like every so often, I would lose my "tone settings". I.e. - My settings for bass, treble, fade, and balance would all get zero-ed out. However, my radio station settings are ok.

Has anyone else had this problem? I know others have had issues with the CDR23 not even turning on, so I suppose I should be thankful that at least it works. If you've had experience in this before, what was the fix? The amp+head unit replacement?

Lastly, would they cover this fix under CPO?
