Sers Leuts, I have had the following problem for some time now. It’s about my car radio (Concert Mod. 2000) – it has become temperature sensitive. At colder temperatures the volume control spins. As soon as I want to turn it even a grid louder or unfortunately, it jumps to max. or min. volume. An intermediate is not possible. OK, min. is still to endure but max…. the poor boxes. As soon as the car or the device is warmed up or you get into the “warm” car in the summer, I haven’t taken the radio apart yet and can’t say exactly what it looks like inside. Can I vosrtellen the controller only as a kind of podi, which pulls together in the cold and thus the contacts can’t be made clean anymore. However, the phenomenon only occurs at the volume, if I like to regulate bass, trebel ect. with the identical bud. Did you ever have such a problem?
