Strange radio knob problem

[Dave at Pelican Parts]

Very odd. I was selecting an MP3 track on the stock radio in my 2012 Cooper, and the selection knob suddenly became very much more difficult to turn. I can still turn it, but the detents (the "clicks" you feel when turning) are much more pronounced, and it takes more effort to move the knob.

I guess I'll be taking part of the dash apart soon....

Has anyone else run into a similar problem? I'm hoping there's just some debris that got into the mechanism that will be easy to clear out.
