hope members could help me with this car phone problem, I have merc e270cdi 2004, had car 2 months, has the phone cradle in arm rest for the nokia 6310i (no phone in car when bought) purchased a nokia 6310i (orange) and the phone works fine outside of the car, when installed in the cradle of the merc the phone works okay via command and steering wheel controls (dial and receive) -ONLY when the car is STATIONARY, I know this sounds daft, but as soon as I am moving/driving in the car I can dial out, but the person receiving the call cannot hear me, but I can hear them, incoming calls I can hear the caller but they cannot hear me, as I have said phone works fine when car is staionary, don;t laugh its driving me mad, any kind members have any ideas or have had the same fault?
