2005 X5 with DSP, NAV, & cell bluetooth - NO sound
Water spilt in back area (trunk). No sound from radio or NAV instructions. NAV display and radio stations work (radio displays song details) and CD changer works (no sound). Cell bluetooth connects, but NO sound. On Radio/NAV display DSP not shown anymore. I am assuming it is the amp, because there is no sound.
1. However could it be the bus system?
2. What is the silver box on the front side of the amp mount (below cd changer)?
3. Is there a way to test the amp? (does the amp have an indicator ight when on)?
