Telephone Background Noise.

[stoutgoose]

2010/11 W204 C350 CDI estate with Comand.

When making a phone call people always complain that I am almost inaudible with lots of 'bubbling' noise interfering with the conversation.

I have tried two different iPhones, changed the tyres from the original 18" Contis to winter 17" Nokians and back to new 18" summer Nokians in the hope that this would make a difference to the background noise, but to no effect.

The noise is worst at motorway speed or on rough surfaced roads.

Mercedes have carried out a software update and lied when they said they'd road tested it on a motorway (it had only covered an extra 3 miles from when I'd dropped it off). It is rebooked, but I want to know if this is a common problem?

Had a similar problem to this on mine, solved the issue by changing the volume settings for incoming and outgoing calls, they are in the telephone options under Bluetooth telephone. Set the incoming volume to max and the out to low. This worked for me

That has effected quite an improvement. Many thanks.
