Hi,No sound on Radio, TV, Navigation, or Phone, 2008 W221 S320CDI just started doing this, May seem daft but seems to happen when the car gets hot since the weather has warmed up? and when it goes off i have checked the Amplifier in the boot and the cooling fan is not running? could it be a problem with the Fan, and the system shuts down? there are other similar posts on the US forums but no fix suggested apart from possible consumer battery needs replacing? any help much appreciated, cheers Dave
