No sound

Hi everbody I`ve got a 528 with radio,tv,cd.tape,satnav had the car almost a year now, about 6 months ago the sound became intermitant.
Now the sound has got completly on everything I`ve tried what bmw said and replug the tuner but to no avail ( any ideas )

that's really hard to say. there could be several things that could go wrong and result in those symptoms. my first "guess" might be a ground connection that has gotten loose. I would look around the amp and see if the ground wire is tight. it could also be a failed amp, or short in the wiring harness, some other failed component... or overheated component as it seems you have every electronic option in your car and all those components can generate heat.

first thing is to check grounding points...

Thank you for your reply , Can you please tell me where the amp is located also had a look under panel in rear behind seats and have only found tv tuner, tm unit , trimble unit had been looking for radio tuner.
I fitted a 16/9 monitor about 3 months ago hoping this might cure the problem " nice unit but still only have 6.4 size screen
