When I first received the car the man from the dealership showed me how to preset the radio stations. He showed me an example by setting station 1 to 106.1. When I got home with my car I started setting the stations to the ones I liked. I reset station 1 to 92.3. But now when I hit that button it flashes back and forth between 106.1 and 92.3 for about two seconds before settling on 92.3. How can I stop it from flashing like that?
