I am having problems with my AUX on my audio sytem. I had the dealer install the AUX cable for my Ipod. It was working great with the Belkin adapter. But now for some reason when it is in AUX it will switch back to a radio station for no reason. Now when I try to put the it in AUX the display does not recognize it. What could be the problem?

power? disconnection?, freezed ipod?, ground?, disconnect power from radio and connect it again (a delay should reset your radio / ipod connection)
