Hello all,

Can anyone point me in the right direction to solve the following problem? -

Audio, DVD sound is fine on initial startup e.g first thing to go to work.
On subsequent startup's more often than not I get a couple of seconds of sound then silence.

It doesn't matter if it is radio or DVD the same thing happens.
I still retain all radio stations on the display & control functions in DVD mode.
Bluetooth telephony sound works fine, both inbound and outbound calls.
Unticking the Bluetooth box in settings makes no difference.

At first I thought it may somehow be temperature related but I've experienced it at all times of day/night and ambient temperatures.

Would a software update possibly solve? if so how do I find what level of software the car currently has?
Dodgy/loose earth? - a client experienced something similar on one of his non-Mercedes cars.

The car is a 2012 S350d LWB with standard audio.

Any pointers greatly appreciated.

Cheers,

Chris
 
Anyone?

I've just seen a recent thread regarding losing the Comand screen apart from A/C controls with talk of it possibly being battery related, could this be the case with mine too?

Cheers,

Chris
