I use a V3 and jabra JX-10 bluetooth headset and get a sporadic pulsatile buzzing coming out of the speakers. This happens whether the radio is on or off, and when the phone is connected via charger or running off of battery. It is amplified when there is an incoming call... I have heard something similar when my phone is next to a personal radio (only when on) or in my wife's old a6, but it is much more pronounced in the rs4, sometimes existing as a continuous low level or occasionally very loud buzz that ceases only when the phone is touched on the external surface. I had no such interference in my b6s4 with symphonyII headunit. This has been happening since the car was delivered... Does anyone else have an issue with a V3 in a b7?

If so, that's a common issue. Bluetooth is spread spectrum and should not cause radio frequency interference. I suspect that you will have this interference whether or not the bluetooth headset is active. Interference on receipt of a GSM call is common, and usually due to poor audio shielding.
