Buzzing sound on the phone [Mio A701 GPS - 130423]

How do I get rid of a continual buzzing interference when I'm using the Mio 701 as a phone. It's a problem that only seems to have arisen since I put a Vodafone SIM in the machine configured for Internet access. Other SIMs don't seem to give this buzzing sound when I substitute them?

I've read other reports of Mio 701's having a buzzing interference on the phone but that's often been put down to the location of other electrical equipment. I get the buzzing sound wherever I use the phone.
