Hi I am ready for throwing the Towel in, had a problem with my sound system everything just went silent. radio CD sat nav etc. tried various fuses checked wiring etc etc., put it down to my DSP amp having a fault, last week i managed to source one from E bay plugged it on and yeah you guessed...

I have same prob with my DSP on a RR 30y anniversary No sound from Head or Sat Nav! Have looked for DSP in left side behind Sub Woofer but the space is taken up with the Sony Video module. Any Ideas were the DSP may be ?????
