07 Galant "Haunted" radio
 

My 2007 Galant likes to change the radio station on its own. It never has a specific time when it does it, but Ive noticed that it does it more frequently when I turn right, or the steering wheel is turned to the right for a period of time, or when it rains and it humid. I have the buttons on the back of my steering wheel, and I do not press them when I turn, so its not that. When it changes the station, it will lock up the buttons, and some times switch them up (turning volume down instead turns it up and vice versa, same with tuning knob.)
Ive been thinking that its bad wiring, or a fuse? (BTW, I know nothing on cars...)
When I took it to a dealer to see what they could do, they blamed it on me for pushing the buttons on the steering wheel... and whenever I wanna show someone whats going on, of course it will be normal!
