Does anyone else have the issue of really poo audio quality for the person on the other end? (i.e. not the sound in the FFRR, but what the other person hears)

SWMBO has complained about mine and I've just called her while she's driving the car. She's right, it's really terrible. Loads of background noise and really tinny sounding, as if she's 30 feet away from the phone.

Any ideas chaps?

New mic unit needed i think, they tend to fail or get clogged with crud over time, try a quick hoover over the vent holes for it and if that doesnt work then new unit it is  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
