My audio system (Mazda 3 from 2006) has shut down and despite repeated efforts to restart the system (based on instructions from helpful Forum contributors), my screen continues to blink ERR. I phoned the Danish import office, and a man there explained that it is an extremely tricky procedure and that even experts have problems resetting the system. Does anyone have an alternative to the 4989/1414 resetting code? I'm getting desperate here Denmark Bob
