I’ll be listening to a CD or the radio and suddenly it skips to a different song or a different radio station on it’s own! Totally bizzare! Can anything to be done?
Thanks for your feedback! 
If this car is “new to you” you might be accidentally hitting the controls on your steering wheel—I have.
If you have had the car for a long time and this is a new problem I doubt there is anything you can do, other than have the unit replaced.
