My radio is possessed!

[Lunchbox]

Anybody know any good exorcists for my stock radio? For the past few weeks I've noticed that my radio is changing stations by itself. I've tried to figure if it's something I'm doing while driving (i.e. turn signals, a/c, windows, turning, accidentally hitting steering wheel controls, etc.) but it just happens even during "normal" operation of my 4R. Naturally I'm going to take it in for service but I'm just wondering if anybody else has had this same problem. On the other hand, it always seems to happen during my favorite songs so maybe it's my singing. Hmmmm....

P.S. if it makes any difference I have the JBL 6-disc changer
