Hi All

I don’t know if I have posted this in the correct section but here goes, after the car had stood for two weeks when on holiday I came back to find the battery dead, did the battery disconnect procedure and re charged and re connected, I now have no sound from any of the equipment, sat nav, radio, tv or cd player, the DSP has disappeared from the menu, I have since disconnected the battery again and re set everything but still no DSP showing, I have checked the connections and they appear to be ok and no signs of water etc, checked the fuses including the one under the plug on the BM unit, the sat nav functions ok but no sound, the radio stations can be selected but no sound and the same with the cd player so do you think it would be a faulty amp or the BM unit.
