Mein Auto: 2000 bmw 740il
UPDATE.. So I went ahead and bought a used bmw 740 gps radio from someone and it worked .. Screen works. radio works. BUt still I can hear that LOUD buzzing distortion noise in ALL speakers. So I also think my DSP AMp is no good. But here is my questions. How could the radio and also dsp amp be broken?
