07 Radio problems

My radio started doing something very strange yesterday. For no reason at all it changes channels, or at least tries to, it goes up a couple of numbers and then back. Almost like it is trying to scan channels. Has any one else had this happen?

do you ride with your windows down a lot?? if so you might have dust or something causing problems... try getting a keyboard cleaner i.e. the arosal can that sprays air and spray it around your buttons to try and get any dust fromm behind them.. let me know how it works

 

I have had this happen just recently in my 06. The volume will go up and down by itself. I tend to drive with the windows down. I will have to try the canned air idea.

 

Thanks for the ideas , I'll give it a shot.
